This is a brian may TB veroboard project, if you wanna build one the veroboard diagram is all over online. It sounds great. Still waiting on my control knobs. The switch is the tone control. The middle position is stock(treble) the top position is mids and the bottom is bass. The volume control isn't part of the normal build but I think it's a great upgrade. That way I can run the gain all the way up without blowing out my ear drums. Instead of the 2n5088 or 2n4401 transistor(I tried both, 5088 was too noisey and 4401 was too full) i used a low noise MPSA18. It sounds just like the 5088 but much less noise. But it still gets insanely off the rails treble boosted even with a low noise transistor so I recommend it. Anyways here's a few pics, i wanted to say more but it's "late" and I gotta get some sleep.
