Acti-Boost - Type A and Type R

A nice pair of boosts/tone shapers, both of which can be made using the same PCB (though only one at a time - come on!).

Both versions utilise fantastic Baxandall active EQ circuitry to keep your tone clean and crisp, offering +/- 15db on bass and treble, and both kick out up to 20dB boost.

So, what's the difference?

  • Type A offers a bit of grit with your boost, pushing into overdrive at the top of the turn.
  • Type R is clean, clean, clean right up to the top end of the range, where a bit of dirt starts to creep in.

You can also opt for more bass-friendly caps, which change the frequency filtering at the input, and also adjusts the EQ control frequencies. These aren't bass effects, but can be used to great effect on your 4 (or 5)-string.

PCB is designed for vertical-mount pots, but you can use normal wired ones if you prefer. Note that the vertical mount pots supplied have round shafts, so will require knobs with set-screw fixing.

Acti-Boost R Review 5 product stars
"I built this kit because I was in need of a real good kick for my lead parts when playing live. Wow! I have to say this thing is amazing. It feels solid and it just sounds fantastic. My guitar really cuts through the mix and there is so much boost on tap! The gain delivers quite a punch if I need it to and the EQ is very responsive. This gave me everything I wanted and so much more!" Leigh - 05/05/2016
Perfect kit 5 product stars
"Perfect kit, well thought, well made. The parts are really good, the pcb is easy to solder on, the board mounted pots mare wiring so easy ! Sounds amazing, easy to build, went together like a dream. Can't say enough how happy I am with this boost. Keep in mind you will have to sort the resistors by hand, but the documentation on the website makes it easy and fast." Shirley - 30/08/2015
Cracking build 5 product stars
"My favourite build yet. The boost pushes my amp nicely and the active EQ gives a lovely top end sheen with some nice low end thump." Tom - 17/11/2014
