FWIW, @aelling's recommendation on changing the orientation of D1 and D2 did NOT work for me. Reversed from the build documents, I had loud thick fuzz with the Sustain fully CCW and quieter thin octave fuzz fully CW but something VERY unusual around the centre of the control..."strange" like...

I appreciate that @Robert - fortunately, I haven't soldered any of those components in place yet so I have some flexibility!

Thanks @Robert. So, based on your response and a little more probing around my PCB, it appears that the 2nd 10k resistor on the bottom left side of my board is a duplicate of the 10k resistor labelled "R2" in the build documents...is that correct (one end of each connects to "R1" and the...

Finally getting around to building my Panspermia (PCB112) and I think I just ran across an issue between the build documents and my board: On the bottom row of the board, I have two 10k resistors on the left while the documents show a single 10k resistor beside two 100n caps. This seems to...

Just about to start my own Panspermia build using the PedalPCB board and I wondered if anyone else had modified their builds according to the notes above from @aelling... I also wanted to ask @Robert if he happened to incorporate any of the notes from @aelling into the current version of the...

I agree with @Feral Feline that I really need to investigate the world of relay switches; however, @jimilee and @Robert have both given me something to consider. Jimi's looks more like the order switching that I can get from Robert's PCBs but that Mad Professor setup might meet this guy's...

I really appreciate the feedback everyone! I think this diagram from @jwin615 comes the closest but "the client" is really looking for a series configuration when both A and B are turned on...and preferably with the ability to swap the order of A and B. Even though @Feral Feline is right that...

Apologies @jimilee, I hope my message didn't sound sassy...definitely NOT my intention. I was trying to say that your question is a good one because it's exactly the kind of thing I'm trying to figure out. In my mind, it was 3PDT master going to order flipper going to 3PDT switches for each...

That's what I'm trying to decide @jimilee, what combination of stomps and toggles do I need to give this guy everything he wants. Bypass and toggle is easy (and I wouldn't need individual stomps for each effect); however, if he wants to toggle between them and ALSO have the option to have both...

Hi Everyone, I'm putting a few circuits into a single box for a friend and he has asked whether I can have a "master" bypass, a footswitch to toggle between the two effects, and the ability to run one into the other (I've also suggested a toggle switch to change the effects order...but that's a...

I'm with you @idlebydesign, my Total Bender board arrived the day I discovered this thread from @neiltheseal. Hoping all the advice here will help put together a full functioning build with this one. BTW, I just completed PCBGM's "Ultimate Pharaoh" and it had a few issues on the board and in...

Hoping to offset some of my Troubleshooting posts with a few build reports. This one is the Thunder Chicken modified to include the option to choose between TWO sweep settings with a footswitch and bi-coloured mode indicator.

All great advice @eh là bas ma I made sure to cover those basic steps first so definitely no loose bits falling around in there. My STRONG sense is that he does NOT solder or use a multi-meter so I have offered/suggested he let me get my hands back on it. Now that it appears to have started...

Sorry @mdc , do you mean the "after" control or the "output" control? Based on the schematic (and my basic skills with reading them), it looks like the "output" control is still downstream of the "after" so any volume issues with the "after" control should still be adjustable with the "output"...

I recently gave my Carcass build away and the new owner has experienced some odd behaviour. Unfortunately, he is now living several thousand miles away from me so I'm trying to troubleshoot "remotely" and I'm hoping some of you might be able to help me narrow the scope of potential causes...

I wondered if it might be EQD's "Black Eye" and then thought of the "SHO" but neither of those schematics seem to match the boost section of the Parenthesis...

After struggling with a couple of pre-amp builds, I was VERY happy to have this Parenthesis fire up ALMOST right out of the box (I initially forgot to install Q5 in its socket and wondered why the output was so low...doh!!). I used a pair of 1N5817 diodes for the octave and a pair of D9G diodes...

As some of you may have seen, I just ran into a similar issue with oscillations with my new Mofeta build so I was back here in the forums looking for advice on troubleshooting again. While test driving a suggestion from @Robert to move my input jack further from the Master potentiometer...

OK...something dawned on me while test driving the input jack suggestion from @Robert My current basement rig has the guitar running to a 2 loop switcher then out to my amp and I have been testing the Mofeta and the Boogie Monster in the first loop. With that arrangement, the input and output...

Thanks @Robert Just moved the input and output as far away from the board as I can. Pedal is still squealing with BRIGHT fully CW and the MASTER around 1:00. I can set both controls full CW without oscillation with the guitar's volume at ZERO but the squeal comes on once I turn the guitar's...
