Christian over at Black Sunshine Media was so enamoured with the Volumizer, however, that I offered to build one for him too. I also took the opportunity to do a better blog post about it, since at the time of doing the original one, I kind of skimmed over some important points. Firstly, some background. The Volumizer is my clone of an MXR Micro Amp, the schematic of which can be found at General Guitar Gadgets. There is basically no difference between my circuit and the one shown there, apart from the layout and possibly a couple of very slightly different parts (due to a lack of local availability). This pedal is a great little pre-amp, which boosts volume and nothing else. It’s nice and clean and only provides distortion if you use it to drive some...
