Hi friends! I have a Little Green Scream Machine (TS808) PCB. PedalPCB also sells the Mean Green Metal Machine (Fortin Modded Tubescreamer), which I love! But I want to try to do the Fortin mod on the Little Greem Scream Machine myself. Looking at the schematics (attached), I see the main...

I'm really interested in the MicroBlend Crossfader, even though I don't own any SMD components. Is there a BOM available somewhere so I can source components before I pick up a few of these units?

I decided to build the Virgil today. (Bad monkey! Bad!) Everything works fine other than the gain knob, which does nothing. What I have currently is a limited EQ pedal. Level, low, and high pots all work, but the gain does nothing. The sound is clear and clean. I resoldered that section of the...

Alright, my seriously smart friends. I need help. I decided to try something different. This TS-50 pedal from AionFX looks promising and unique. It incorporates three inductors and a DC converter. I finished the build and it passes signal both in bypass and active, but it's NOISY! There's a...

Just finished putting the Acrobat together. It lights up just fine. Testing with a multimeter, I'm getting voltage to all of the ICs. I assumed (and partially still think) there's a grounding issue, but I'm not sure. Of course, it gets power, so maybe not. I've tried: - Scraping all the paint...

Has anyone else discovered that the FCR14422 washers don't fit the Acrobat? The holes on the PCB are too far forward. They should be right next to the first row of pins for the S4 jacks. I tried bending the pins on the washer, but they snapped off. Is there another way to ground the PCB to the...

Hey, friends! I finally got around to building the Pineapple (Wampler Pinnacle). I found a thread giving the recommended values for biasing Q5 and Q6, but I need help getting the drain voltage below 6.19 and 7.09. I get sound in active and bypass, but the effect doesn't seem quite right. It's...

I've built around 150 guitar pedals and run into this problem 4 or 5 times. Everything is working fine, so I box it up. It's still working until I tighten down the pots. Suddenly, there is a grounding issue. (The power draw goes way up, the LED won't light up, and there is no sound.) When I...

This is a weird one, and I can't find the information I'm looking for anywhere. I built an Oasis (Dunes) pedal. It only turns on when it's plugged into my 1 Spot Current Reader/Cable Tester. I put it on my board, which uses isolated power (Truetone 1 SPOT PRO CS12 12-output Isolated Guitar Pedal...

The Leprechaun (EQD Rainbow Machine) is such a weird, extraordinary pedal! I called mine the Frobozz Machine after being inspired by the recent Zorkmid pedal (which is PHENOMENAL, by the way). Unfortunately, my Leprechaun has a WEIRD QUIRK. The dispersion knob function (which affects the lengths...

I am having a heck of a time trying to find a mini slide switch for the Tommy III build. It isn't available through Tayda, and I'd rather not order through Mouser or DigiKey if possible, since shipping is expensive. Is it possible to omit the switch? If so, what should I put in its place?
