A pedal signal chain is the path your sound takes from guitar to amp, and the usual order is: tuner, pitch and wah, compression, drive, modulation, delay, reverb. Change that order and the same pedals sound different. This guide gives you the starting order, the reasons behind it, the wiring, the amp’s effects loop and the fixes for a noisy board. Every order here is a starting point, and we show you where it is worth breaking.

What a pedal signal chain actually is
Your guitar produces a small electrical signal. It travels down a cable, through each pedal in turn, and into the amp. A guitar signal chain is simply that route, together with every effect the signal passes through on the way.
Each pedal only hears what the pedal before it sends. A compressor squashes the signal before it reaches your overdrive. A delay repeats whatever the pedals ahead of it have already done. That is why order matters: the pedals are not independent, they are a relay.
Our own guide to a five-stage pedal chain for guitarists and bassists covers the same idea from the bass side if you play both.
The standard order, from guitar to amp
Most guides agree on the broad shape. Guitar World’s advice is a tuner first, touch-sensitive effects near the front, then pickup-sensitive effects such as fuzz, compressor and overdrive or distortion, followed by modulation, delay and reverb. In practice:
| Position | Pedal type | Why it sits there |
|---|---|---|
| 1 | Tuner | Gets the cleanest signal, so it reads pitch accurately |
| 2 | Wah and pitch shifters | They react to the raw guitar signal and to your playing |
| 3 | Compressor | Evens out dynamics before the gain stages |
| 4 | Overdrive, distortion, fuzz | Shapes the core tone |
| 5 | EQ | Sculpts what the drive pedals produced |
| 6 | Modulation (chorus, phaser, flanger, tremolo) | Works on an already shaped tone |
| 7 | Delay | Repeats the finished sound |
| 8 | Reverb | Adds space around everything before it |
The short rule behind the table: effects with the most dramatic impact generally go at the front, while effects that refine details go towards the end, with exceptions.
Why each pedal goes where it does
Tuner: first, always
A tuner works best with an untouched signal, because the purer the signal, the more accurately it can detect pitch. Placed first, it also lets you mute the whole board while you tune on stage, without switching off each effect.
Wah and pitch: the front of the chain
GuitarPlayer notes that pitch shifters, volume pedals and wahs tend to go first, with drive pedals after them. A wah before overdrive sweeps the frequencies of the clean guitar into the drive stage, which gives the vocal, singing quality associated with classic 1960s and 70s wah tones. Put the wah after a distortion and it sweeps the already distorted signal instead. Guitar World says distortion before a wah can give a more dramatic or refined sweep, depending on the character of the distortion pedal, so both are valid. Try each and keep the one you like.
Fuzz: the fussy one
Classic fuzz circuits, particularly the Fuzz Face type, expect the impedance of a guitar pickup. GuitarPlayer advises placing them first in the chain, so they interact properly with your guitar’s volume knob. If your fuzz sounds thin and spitty behind a tuner or another buffered pedal, move it to the front. Bassists have the same option: a bass fuzz such as the Aguilar Fuzzistor sits in the gain section of a bass chain.
Compression: early or late
Compression is the pedal with the biggest choice of position. Placed at the start of the chain, it gives more sustain, a tighter tone and more harmonic information. Placed at the end, it keeps levels consistent across all your pedals, but it can smooth out reverb trails and take some life from the sound.
For guitar, start early. If you play bass, a dedicated bass compressor such as the Aguilar TLC Compressor is built for that job, and the same early-in-the-chain logic applies.
Overdrive and distortion: the core of the tone
Drive pedals sit in the middle because they are sensitive to how you play and they feed everything after them. A classic overdrive such as the Boss OS-2 or the Electro-Harmonix Soul Food belongs here. If you want to understand what these pedals are doing to the signal, our explainer on what overdrive is and how it shapes guitar tone goes into it.
When you stack drives, the usual habit is lower gain first (a boost or light overdrive) into higher gain after it. A boost in front of a gain pedal pushes it harder, while a boost after it simply makes the whole thing louder. Same pedals, two different jobs.
Modulation: after the drive
Chorus, phaser, flanger and tremolo generally come after compression and drive. There is a sound reason. Drive pedals complicate the waveform and add overtones, which gives a flanger or phaser richer harmonic content to emphasise. It is the reason a flanger after a crunchy tone sounds so dramatic. Our guide to what a flanger does describes that jet sweep in detail.
Turn the order around and you get something else. Modulation placed in front of a distorted amp or overdrive pedal can produce thick, jet-like phasing and flanging. Eddie Van Halen, who generated his distortion from the amp, is the example Guitar World gives. It is a legitimate tone, just a different one.
Delay and reverb: last, delay first
Delay goes before reverb, and both sit near the end, so the repeats are washed in space rather than the other way round. There is a second reason delay follows the drive. An overdrive pedal responds to your playing dynamics, so it should come before effects that are less sensitive to them, such as delay. Delay repeats have a consistent tone, and putting delay before overdrive throws away the dynamic range the drive could give you.
If you want a delay with a looper in one box, the used TC Electronic Alter Ego Delay/Looper fits this slot. For the reverb slot, the Electro-Harmonix Holy Grail is a reverb pedal that goes last on the board.
How to connect your pedals, step by step
The wiring is easy once you know one rule: signal flows into a pedal’s input and out of its output. Some pedals label the jacks “instrument” and “amplifier” instead of input and output, but the idea is identical.
- Turn the amp down or off. Connecting pedals with the amp live can cause loud pops.
- Work out your cable count. For several pedals, you need one cable per pedal plus one more from the guitar to the first pedal’s input. Four pedals means five cables.
- Guitar to the first pedal’s input. Use a standard instrument cable. On most pedals the input is on the right-hand side as you look at it from the front.
- Output to the next input. Run from each pedal’s output (usually the left jack) into the input of the next one, following your chosen order.
- Last output to the amp. The final cable goes to the amp’s input.
- Power everything. Most pedals take 9V DC. Use the right supply, with the correct polarity and current rating for each pedal.
- Turn the amp on last. This keeps the clicks and pops away from your speaker.
The point that catches beginners is direction: the signal goes in on one side and out on the other, so reading the board left to right can mislead you. Trace the cable from your guitar rather than trusting how the pedals look on the floor.
Short patch cables save space and reduce clutter, and a decent power supply saves headaches later, which brings us to noise.
When to use your amp’s effects loop
Many amps have an effects loop. It lets you split the chain in two. Your tuner, wah, compressor and drive pedals go in front of the amp, into the normal input. Your modulation, delay and reverb go in the loop, between the amp’s preamp and its power section.
The benefit is clarity. If you get your overdrive or distortion from the amp itself, delay and reverb in front of it get distorted along with the guitar, and can sound muddy. In the loop they sit after the amp’s own gain, so repeats and reverb tails stay clean. Pedals that add gain, such as boosts and drives, are normally kept out of the loop.
This is the standard approach for high-gain setups. If you play mostly clean or use your pedals for the drive, running everything into the front of the amp is fine, and simpler. Whichever you choose, check your amp’s manual for how the loop is wired and what level it expects. If you are shopping for an amp with a loop, our guitar amps and combos are a good place to see what is on offer.
Fixing a noisy, muddy or thin chain
When a board sounds wrong, it is rarely the order alone. Work through these in sequence.
Hum and buzz
A steady low hum is often a ground loop. GuitarPlayer reports that isolated power taps prevent ground loops, and that pedals built on bucket-brigade circuits, such as analogue delays and choruses, are particularly susceptible to coupling noise. The same article notes that daisy-chaining power supplies ties all the audio and power grounds together, which sets up ground loops between pedals. The cure is a supply with isolated outputs, such as the Strymon Ojai power supply, rather than a daisy chain splitting one adapter between many pedals.
Hiss
Hiss usually comes from stacked gain. Turn down the input gain on the loudest pedals first. A noise gate placed after the highest-gain pedals can tame what is left. Compression sitting after your drive pedals also lifts the noise floor, so if you hear hiss, try moving the compressor earlier.
Muddy or lifeless sound
Muddy usually means time-based effects sitting in front of heavy gain. Move delay and reverb to the end of the chain, or into the amp’s loop. If the tone feels dull rather than muddy, check whether a fuzz is sitting behind other pedals that change how it loads your pickups, and put it first.
Thin, shrill fuzz
A classic fuzz behind a tuner or buffered pedal can sound thin. Try it first in the chain, straight from the guitar.
Cables and positioning
Unshielded cables pick up interference. Keep power supplies away from digital pedals and from the guitar’s pickups, and replace any cable that crackles when you move it. Old or damaged leads are the cheapest thing to swap.
When to break the rules
The order above is a reliable default, not a law. GuitarPlayer’s Alex Lynham makes the point in his pedal order guide: for every conventional placement there is an alternative that some player has made work for their sound. StewMac’s Paul Lampley says much the same, that you should think about what each effect does and how it interacts with the ones around it.
A sensible way to experiment:
- Change one pedal at a time and play the same riff.
- Note whether the change affects tone, noise or feel.
- Keep the switch if you like it, put it back if you do not.
- Try the big movers first: compressor early or late, modulation before or after drive, wah before or after drive.
Perspective: why we set up the chain in the shop
We see a pedal chain as part of the instrument, not something added afterwards. Every guitar we sell is set up and inspected by us, and a chain behaves best when the guitar underneath it is in good order: cleanly intonated, with fresh strings and a healthy signal.
That is why we like to see a player’s pedals alongside a guitar. In our Huntingdon shop you can try instruments in store, and plugging into a clean signal is the best way to hear what each pedal does to it. Start with the order in this guide, then adjust it to your hands, your amp and your style.
If a board gives you trouble, bring it in. We offer guitar setups, servicing and repairs, and we support what we sell after the sale.

Build your board with us
We sell new and pre-owned electric, acoustic and bass guitars, along with amps, effects, cases, strings and accessories, so you can build the whole chain from one place. Browse our effects and setup services, or have a look at the electric guitars the board is going to follow.
If you want a pre-owned pedal for the drive slot, there are pieces such as the used Jam Pedals Pink Flow in our range. Stock changes, so look at the shop for what is currently available. A tidy board also needs a case or gig bag: our guitar cases and gig bags cover the guitar that feeds it.
A worked example: a first board
Say you have five pedals: a tuner, an overdrive, a chorus, a delay and a reverb. The chain from the guitar is:
- Guitar into the tuner.
- Tuner into the overdrive.
- Overdrive into the chorus.
- Chorus into the delay.
- Delay into the reverb.
- Reverb into the amp.
That is six cables, one per pedal plus the lead from the guitar. Set the overdrive to a light crunch first. Add chorus until it sounds present but not seasick, then set delay repeats lower than you think you need. Finish with a little reverb, because it builds up fast.
Now add a wah. It goes between the tuner and the overdrive, since it works on the clean signal. Add a compressor and it goes before the overdrive too. If you later buy an amp with a loop, move the chorus, delay and reverb into it and compare how the repeats sound.
A second example for bass: tuner, compressor, fuzz or overdrive, then modulation and delay. The same principle holds, and a bass fuzz or compressor sits in the same slot as its guitar equivalent.
Power, cables and layout
The order is only half of a good chain. The rest is physical.
- Power: use a supply that gives each pedal the voltage and current it wants. Isolated outputs help keep noise down.
- Cables: keep patch cables short and good quality. Excess length adds clutter and can add noise.
- Layout: place the pedals you tap most at the front edge. Keep a tuner where you can see it.
- Footprint: a board that is too crowded invites accidental stomps. Leave space between pedals you switch quickly.
- Spares: a spare cable and spare fuse in your gig bag are cheap insurance.
When you restring or have the guitar set up, it is a good moment to retest the whole chain, since new strings change the response of drive pedals. Our in-store restring service and strings are there for this.
FAQ
Does the order of guitar pedals really matter?
Yes. Each pedal processes the signal it receives from the one before, so the same pedals in a different order give a different tone. For example, delay before overdrive loses the dynamic range the overdrive could offer. Use the standard order as your starting point and experiment from there.
Where does the tuner go in a pedal chain?
First. It reads pitch most accurately from a clean signal, and at the front of the chain you can silence the whole board to tune. The exception is a classic fuzz that wants to sit directly after the guitar. In that case try the fuzz first and the tuner second, and see which you prefer.
Should delay or reverb come first?
Delay first, reverb after it, with both near the end. Guitar World recommends delay before reverb so the repeats sit inside the reverb’s space. Reverse them if you want a more unusual, washed-out repeat.
What is the right-to-left rule?
On many pedals the input jack is on the right and the output on the left, so the signal appears to travel right to left across the pedal. It is a wiring convention, not a rule for the order of effects. What counts is that your guitar goes into an input and each output goes into the next input.
Do I need an effects loop?
Not to start. If you run your drive from pedals, putting everything in front of the amp works well. An effects loop pays off when you use the amp’s own distortion and want delay and reverb to stay clear after it.
