I recently bought a Tap Tempo board from another site in hopes of adding this functionality to my Cataclysm (Disaster Transport Jr.) build. I’ve been going through some of the documentation today and think I have a handle on just about everything except the difference between the Cataclysms...

Thanks Chuck. I'm close to finished...and I've used sockets in a few places (C18, C19, R4, R11) to test drive the mods before finalizing my component selections. Looking forward to the final results (provided I haven't killed the 4393 of course!).

Thanks. I think I feel my heart rate slowing...at least a little bit, anyway!

Do you think it might be low enough to let my DMM "beep" in continuity mode? Doing some more reading...and crossing my fingers! ?

At the risk of exposing my electrical ignorance, I just want to check on something that has me a little worried: Today I soldered five SMD versions of the MPF4393 (MMBF4393) transistors into my COVERT Overdrive build...something that is relatively new to me. As a check, I measured for...

Thanks!

I couldn't get any continuity between the input pad and the first component pad (R2 I believe) no matter what I did so I quickly soldered in a jumper and the distortion circuit roared to life! I think one the input pad must have lifted (R1 and R2 were showing continuity so my assumption is that...

Amazing how much more detail you can see in these photos...even compared to my magnifying headgear! Lots of resin dust may appear like solder "hairs" (I've looked close and there aren't any bridges) and what appears like a solder bridge on the distortion switch in one photo is shown to NOT be a...

Thanks PedalPCB...I'm kicking myself for not checking the continuity before posting (that's one of the first debugging steps, no?). Anyway, a couple of interesting things about the resistance: if I follow the trace from the input pad to the connection at R1, there is infinite resistance...

Hi Everyone! Having searched the forum and read several threads on troubleshooting the Parentheses Fuzz, I still can't seem to solve the problem I'm having so I'm hoping you might be able to help me out... A friend of mine recently asked me to debug a pair of Parentheses builds he was working...
