Caline CP-22 Purple Smoke Clean Boost

Got mine in the mail today. Tried it out and it sounded like there was a bit too much low cut for my taste. Figured that this won't be all that big of an issue, so i fixed mine by replacing the 1µ bypass cap with 47µ. Sure, the "clean" isn't there anymore when the gain pot is maxed. I do find this quite usable with this one cap replaced. The 4k7 in parallel with the level pot is somewhat stupid solution. 5k log pot would have sufficed. Mine didn't have a battery snap, but the pedal came with a battery adapter for standard barrel plug. This circuit, like most of the Calines i've seen, are nicely build cheapos that are easy to mod. This one could be turned into a "Channel 2" with minimal effort. One would just replace the transistor for a MOSFET, short the bypass cap, add 8M2 from gate to ground and a zener from source to gate. Also one would need to tweak the value of that 22k. Nevertheless, it would be rather easy to do. I do like mine as it is, with one cap upped. Didn't bother with the bypass switching or the LED for the schematic drawing.

Grah. Got couple of the designations wrong. Fixed.
