Hamstead Soundworks Artist 20+ RT MkIII, 20W Handwired Combo

Hamstead Artist 20+RT | MKIII

The Single Channel Masterpiece

Our fresh approach to amplifier design has led to something rather special. This amplifier will surprise you. Designed to encompass maximum tonal versatility, without compromising on tonal quality. Delivering everything from shimmering cleans to warm, natural, harmonically rich overdriven tones. It's powerful, portable, and it loves pedals and guitars of all types. You will be sure to love it too. Meet the Hamstead Artist 20+RT.

Sonic Versatility:

From the warmest of mellow jazz through sparkling country cleans, to mean, gritty blues and classic rock grind, this amplifier has it covered. All with a depth, clarity and feel that allows the personality of the player and guitar to really shine through – perfect too, for all your favourite pedals & effects. The Artist 20 also features a 'Voice' switch that adds presence and bite to the upper midrange, and Bright switch that adds a touch of brilliance to the top end.

Power at Your Fingertips:

Don't be fooled by the 20 watt power rating, you’ll believe it's 40, maybe more, when turned all the way up (with barely any background noise) – but you can still tame it, and the Triode mode will drop the output down to 12 watts. Wind the Master down more, and all the touch sensitivity and nuance is retained down to almost whisper levels – perfect for stage, studio, or practice.

Reverb + Tremolo:

The Artist 20+RT includes our signature Reverb and Tremolo circuits. The Reverb has depth and tone controls, allowing it to suit different styles of music, guitars and venues. The Tremolo has depth and speed controls, using analogue control of the signal to give a smooth, even sweep at any speed. Both are switchable on the front panel or using the included footswitch.

Built to Last:

Every aspect of the Artist Series’ construction is of the highest quality. From the eyeleted epoxy glass boards, to the thick aluminium chassis and British made custom wound transformers, the Artist series is nothing short of world class, marrying classic and contemporary design and manufacturing techniques. All amps come with a 5 year warranty as standard.


  • ‘Bright’ switch on the front. When engaged, this adds a touch of top end brilliance to the tone - especially useful with some guitars equipped with humbucker pickups.

  • A ‘Voice’ Level switch. There are now 3 presets, allowing you to choose the amount of mid-upper boost. Choose from: 2dB, 3.5dB and 5dB.

  • ‘Clean Gain’ switch. The new ‘Lo’ setting lowers the preamp gain, and gives you more clean headroom.
