Hi there. I recently picked up this pedal for cheap and I love it. However, it does not quite achieve unity gain when engaged and comes nowhere close unless the eff.level pot is dimed. So even with this pot maxed out, there is still a noticeable volume drop. Its significant enough to cause a problem in live mixes.
I was wondering if there was a simple mod I could make to get to unity? Its all through-hole and I'm comfortable with soldering etc.
As it stands, I have to put a clean boost after...

After finishing the Disappearing Act ducking spring reverb, I decided to do a version that uses the Belton brick for people who want something smaller footprint or who want some other features. I chose the BTDR-3 since it can do adjustable decay time and stereo output. The Escape Artist uses the same envelope follower topology, but the reverb path is different. The optical compression is the same, though tailored for the output of the brick. It's capable of huge washes. It can also do mono or...

Hi all,

Last night I finished my 2nd project with great hopes, however all I got was a DI sound mixed with a rather hi-freq hiss, and nothing else. I've followed the below project. Also the dist. switch (which is an on/on, 3-pin switch) totally kills the sound when switched on one side.

First I noticed that I misplaced the 560pf on K1/L1 into J1/L1, fixed that, and traced all of the pins one by one and all is fine, no cold solder, jumpers & cuts are just fine. There's no short between...

Hello,

I'm Im in a but if a J Mascis rabbit hole and have been trying to get as much info on the deluxe big muff as I possibly can with not much information publicly posted. Here's kinda what I have so far

EH1318: first version 77/8

EH1330: switched to long printed board
EH1330A

EH3053
EH3053A
EH3053B
EH3053C

EH3054: switch to short boards, units here on our commonly have ghost buzz when bypassed. Soul preacher switched for 3080 compressor?
EH3054A
EH3054B
EH3054C: series parallel units...

Found this while browsing various Russian parts so thought I’d share it.

Japanese with English. Nice photos of old components.

And a Transistor Museum linked from that site:

:shock:

Moved to the debugging subthread

Has anybody ever built this circuit?
The description sounds interesting, but I couldn't find a layout.

Fred Briggs disappeared from the scene some years ago.

Hi guys,

I just built a Rangemaster clone with point-to-point wiring (dead bug?) and it seems to work fine with a battery, but when I plug in the power supply I get this constant thumping noises. Also the LED doesn’t come on with either the battery or the power supply. I know the LED is alive and the polarity is right because when I attach the battery snap directly to the LED it lights up. Also also, I’m not sure if this is how it’s supposed to be (never have played the original) but when it’s...

Just bought a DIY Landtone Delay pedal last week but can't manage to make it work after double checking and resoldering each component. The effect itself is not being generated when the pedal is activated.

HELP!!!! I have been given an amazing 90s George Dennis Vol/Distortion pedal. It's a GD100 Wizard Rock ( Not the Wizard Blues ). A beast in both tone and size.
The Dist circuit is a high gain (yet quiet) 90s distortion with warmth/depth and a great 'character'. I would love to be able to get the DIST pedal in a small box on its own, but I don't know what it's based on. Or at least a schematic so that I can build my own. As I said, just the Dist/Gain circuit - no volume. Anybody familiar with it?

Not my work, I just found it and made it into a PDF.

Now you can make an original copy.
(I cannot personally confirm if it’s confirmed)

Hi,

I've built the bootleg / moonshine clone from .
One thing that makes little sense to me is that the volume and blend have very similar effect since the direct signal is not affected by the volume pot. This is confirmed by looking at the schematic at .

* Does anybody have access to a moonshine and confirm that this is indeed the case? I somehow recall Josh Scott mentioning that the moonshine schematics online were wrong.
* How would I modify the pedalPCB schematic to move the volume to...

I like to use relays on the builds which I box up, and I have been making use of a simple relay design by Chuck D. Bones at the PedalPCB forums:
relay-v1.1-schematic.png

I'd like to share the schematics, gerbers, etc here:

There is a through-hole version for self assembly. I've been using this for a while.
relay-v1.1-build.png

I also did a SMT version for assembly at JLCPCB. It's the same schematic but a smaller footprint:

I use the Fujitsu FTR-B3CA4.5Z or...

Anybody have the schematic for a Zoom 9050? I'm getting all sorts of artifacts and noise through some effects even though I swapped the caps on the analog board.

I recently got a Tonex pedal and wanted to capture a couple of the tube amps I've made. After some digging, I found that you don't need the Tonex Capture. All you need is a decent audio interface, a mic (or two) and a reamp box. (There's a good video on YouTube by Pete Thorn showing this.)

I didn't have a reamp box so I decided to build one. It worked out much better than expected so I'm sharing my design in the hope that others will find it useful.

A quick survey of reamp box designs led me...

Not sure how useful this will be to anybody but I figured I'd put it up here before I lost it... :lol:

Edit - Added missing values and pot names (best guess on the pot names)

HEY GUYS
Still on the issue of Fuzz Face VS WAH...

this button WAH WAH TRICK seems to be the pregain, does anyone have an idea if this is it, or is it a buffer?
