Hi everyone! Hoping you might have some suggestion on how I can resolve a minor issue I'm having with a new build. I just completed a bass pre-amp build and it works great...with one exception: As I turn down the GAIN, the output is reduced as expected, reaches "0" before full CCW rotation...

I completed my Gravitation build and noticed the 78L05 was getting QUITE warm during a 5 minute test. Quickly realized the regulator was flipped 180 degrees and made the correction. Everything SEEMS to be working OK but just wondered what kind of damage (if any) may have been possible?

I'm working on the PedalPCB Tone Generator and it's my first real foray into SMD components outside of the odd few repairs I have done in the past. Everything seems to be going fairly well but the silk screen shows the orientation of a PDIP-8 type of chip and I can't figure out where PIN1 is on...

Before installing my Two Tone Fuzz board in its enclosure...I loaded it up with 3 silicon PNP transistors just to make sure it worked (I'm waiting for some PNP Ge transistors to arrive but it might be a while given our current postal strike here in Canada...). The silicon PNPs came from...

A friend of mine has asked if I can build him a Hyped Fuzz with a "Blend" or "Mixing" knob instead of the 3 way Mode toggle. In my research, I came across a post from @Grubb (Hyped Fuzz Mode Blend) who was trying to do the same thing but didn't receive any answers to his questions so I will ask...

I recently purchased a batch of 30 D9D diodes from a Ukrainian seller on eBay and sat down to measure the forward voltages tonight. What I found appears to be in line with the measurements that @SillyOctpuss posted in this thread...

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...

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...

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.

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...

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...

After setting aside my Boogie Monster which continues to squeal at high volume settings, I put together a Mofeta build...and now it's squealing on me too! For the record, I've managed to tame the squeal in the "normal" channel by setting the bias on Q2 at 4.5v; however, with the "bright"...

Completed my Boogie Monster build and it is sounding pretty good except I seem to be one of the unfortunate ones with some squeal/oscillation at the top ends of the VOLUME and GAIN controls. I followed the advice from @Chuck D. Bones, socketing R102 so I could swap the stock 100r with 1k and...

Hi PedalPCB friends! I'm aiming to make a modification to a NON-PedalPCB circuit but I thought I'd check in here...a) to solicit your wisdom and b) to share the discussion with those of you who may grapple with a similar situation down the road. As shown in the schematic below, the board has a...

Hi everyone, I've been reading a little more about the sonic differences between the Greer Lightspeed and Southland overdrives and the general consensus seems to be that the Southland is more "mid-scooped" (in addition to the differences in gain). Looking at the PedalPCB schematics for the...

Hi folks, I'm currently working on a HotCake build using a vero layout and wanted to implement a suggested mod to create a "bright switch" based on the stock 470pf cap (C4 on PedalPCB's Awful Waffle). The suggestions I've read say to put the 470pf cap on one side of a DPDT and a jumper on the...

A while back I built a PedalPCB Mach1 for a friend of mine and was recently reminded how great the circuit sounds. Knowing that the component count is relatively low, I looked into a couple of vero layouts and noticed that the one found here...

After mis-printing my original Depot enclosure, I ordered a replacement for my completed board mounted circuit and then got my hands on a second PCB so I could wire the pots to match the wonky enclosure. I'm quite happy with both builds now (including the cap switch that selects between the...

Hi everyone! I just dropped four 2N5088s into my completed Dung Beetle PCB to make sure it worked before boxing everything up...and it did (YAY!)...but I thought that I would ask if there was a consensus on hfe values for the Dung Beetle. Looks like the four I chose measure around 235 hfe but...

Hi everyone, Slowly getting back to my build projects after our move last fall and one of the first things I'm going to tackle is the Marigold. I love having an external bias control to adjust how smooth or spitty the fuzz sounds so I'm wondering which resistor would be the one to...
