I figure rather than clogging up the "What's your next purchase" thread I'd start my own thread (with hookers and blackjack!) to clog up. So recently I've gotten hooked on the idea of building my own pedals. Not to save money (although it is quite a bit cheaper to build rather than buy some of the more boutiquey ones) but as a hobby. Currently I've been doing PCB builds (that is, buying an unpopulated printed circuit board, all the components, and all the hardware) which is, realistically, EZ Mode, but I plan on (eventually) moving to veroboard and stripboard builds, and even more eventually building my own circuits. Anyways, I digress. Here's what I've built so far! First build is the GuitarPCB.com Mastodon, based off the ZVex Woolly Mammoth but with some tweaks. Controls are the same as the Woolly Mammoth, Volume/Wool (fuzz)/EQ/Pinch (gate). Sounds fantastic for bass and guitar, but I think it'll ultimately end up on my bass board. Had some serious issues getting it to work that wound up being a misunderstanding of the PCB - what I thought was a second output trace was actually a ground, so I wound up creating a nice little short that killed all output. Easy fix, once I figured it out. My next and most recent build is a PedalPCB.com Thermionic Distortion, based off of the Friedman BE-OD. It also gave me some trouble... first time I powered it up, one of the resistors exploded on me. Some asking around and fine analysis revealed a bridge between Vcc and ground that caused it to overload the first resistor, a measly little 10R. Fixed that, installed a new resistor, and crossed my fingers... and it worked! This pedal is fucking mean sounding. I'm having a LOT of fun playing with it. Controls are a pretty basic Bass/Treble/Presence/Volume/Gain with a fancy dancy "Tight" control that, well, makes it tighter. My wiring is getting a bit cleaner and my soldering is getting better, I think. Still not quite there yet but serviceable! This one is staying on my guitar board, and sounds awesome with my OD9 running into it. Next time I can afford to build a pedal I'm looking at either doing a chorus or a compressor - something a little more complex. Either way I'll be documenting it in this thread, even if I have to bump it myself!
