TwinStomp Booster review

  • £155

A unit designed to drive your valve amp to tone heaven

TODO alt text

Our Verdict

£155 is a fair price for this kind of quality, and a step towards that elusive 'Brown' sound. If you own a quality valve amp and want to push it a little - or a lot - harder, you should try one out right away.


  • Great tone, cool battery compartment, easy to screw to your pedalboard.


  • Not an unfair price for this amount of quality, but it's still a lot for a booster pedal.
Buying options

The man behind the TwinStomp Booster, Adam Betts, did what many players feel forced to do when struggling to realise the tone they hear in their heads: he built a pedal himself.

Using a widely available design based around Mosfet circuitry, he simply constructed a stompbox and went from there. However, as a commercially available clean booster with two switchable settings proved difficult to find, he decided to incorporate that into his design and create something new. There is a swathe of technical info on the TwinStomp site if you'd like to really get to grips with the innards of the pedal.

The pedal offers two settings. Pedal two offers a maximum of 22.5dB of boost and is slightly hotter than pedal one - with each possessing its own level pot. There's an on/off switch and a blissfully simple-to-access battery compartment: just tug on the ring-pull and it pops out for easy replacement. It's true bypass too.



Boost 1

Boost 2

The TwinStomp does its job very well indeed. Remember it's a boost, not a distortion or overdrive pedal, so it works best with all-valve amps to push them to (and beyond) that magical sweet spot of harmonics and drive. As everyone within about five miles will attest, it makes our hand-wired Marshall 1959 roar like a pride of lions when gazelle school kicks out for the afternoon. Moreover, it doesn't change your amp's core tone or EQ to any great extent.
