This is the P.C. Boost from Kink Guitar Pedals.
Based off the iconic Micro Amp, The P.C. Boost will help boost a nice clean sound or drive your tube amp into gain land. All this while remaining politically correct.... We can't go upsetting anyone now, can we?
Made in Melbourne, Australia.
Simple, one-knob-wonder that provides a great clean boost. I use this pre-gain to push my OD channel on the amp and it works a treat - and also on the clean channel too (esp when playing on a guitar with single coil p/ups).
