    BS170 Bass Fuzz

    Here's a very straightforward MOSFET bass fuzz I've been messing around with on ye olde breadboard for the past week or two for the bass player in my band. SHO —>the bass half of a James tone stack—>MOSFET fuzz face The 'fuzz' adjustment comes via the SHO's crackle pot, with a heavy amount...

    1590BB top mount jacks

    Hi folks, Just wondering if someone here could point me toward a PPCB project that you've made featuring a 1590BB enclosure, top mount jacks, and (here's the important thing) clearance in the drill template for plastic enclosed jacks to clear the pots. I have a 1590BB leftover from before...

    LND150 SHO variant (LND 'HO)

    I bought a bag of LND150 depletion-MOSFETs a while ago and have been entertaining myself by figuring out ways to use them. In case anyone needs an extremely low parts count boost, here's a SHO variant that takes advantage of the LND150s low input capacitance and internal ESD protection to drop 3...

    Source for M12.7 x 1.0 hex nuts?

    I have a bag of these DC jacks that were sent with the incorrect hex nuts. Just curious if anyone happens to know of a source for the proper ones - I believe they're 12.7x1.0. They don't seem to be available at my normal spots.

    2x LND150 OD

    Hi all, Here's an overdrive circuit that I put together recently and have been enjoying a lot. It's pulled together from bits and pieces of Spaceman's Saturn, Fairfield's Barbershop, and a circuit from a DIYStompboxes user (Johnny Reckless) called the Moonlandr. It's very straightforward, a...

    LND150 SRPP OD

    I've been futzing with this pleasant-sounding overdrive over the past couple weeks, and finally built it up into a working pedal. It's based on RG Keen's example of an SRPP circuit which is in turned derived from Jack Orman's mu-amp/mini booster. It uses LND150 depletion MOSFETs and the gain is...

    REQUEST Aion Spectron & Quadratron

    Hello! Just curious if anyone's happened to put together drill templates for these projects? I'm about to put a Tayda order in, and I figured I'd ask the crowd before I went ahead and tried to suss it out myself. Thanks in advance!

    SOLVED Pitch Witch - blend issue

    I have a pitch witch build that was previously working a-ok. I plugged it in today and it's gone a bit off. Per the schematic: https://docs.pedalpcb.com/project/PitchWitch.pdf If I've got strong clean signal with the blend knob fully CCW, and strong delay-only signal with the knob fully CW...

    Modified B&M Fuzz

    I heard 'Girl Like You' come on the other day and was reminded of that song's great fuzz tone in the lead part. Legend has it, he used a B&M fuzz unit for the track. It's a Colorsound pedal, not too different from a Big Muff, in the same family as the Supa and Jumbo Tone Benders, as well as...

    VoodooLabs Optical Bypass

    Hi folks This is a bit of a utility build report, but hopefully some others will find it useful? In any case, I've had a few builds lately with switch pop that wasn't cured through the usual methods. In digging around for a solution, I found the schematic for optocoupler-based bypass that...

    Parasit Raygun Youth

    If you haven't stumbled across Frederik Lyxzén's Parasit Studios page, it's worth checking out - he has a slew of DIY PCBs of original circuits, vero layouts for some classic oddball effects, and some really useful utility circuits. I was looking for an extremely blown out sounding fuzz that I...

    LND150 // Differential Pair Distortion

    In the spirit of sharing breadboard projects, here's a circuit I pieced together over the past few weeks. On the breadboard... Got some PCBs... Realised I made a few goofs laying it out, tweaked to suit, and here's the adjusted schematic... The LND150 MOSFETs are popular with solid state...

    Tayda drill coordinates for 1590BB or 1590BB2 top mount jacks?

    Hi pals, I'm going to take the plunge and try Tayda's drill service for the first time, I'm just curious if anyone happens to have the magic numbers handy to allow top mount jacks to work on a 1590BB with pot insulators and enclosed 1/4" jacks (ie...

    1590BX2 vs Intelligent Relay Bypass pcb...?

    Hi folks, Just curious if anyone has built up a loop switcher with relay bypass boards inside of a 1590BX2 enclosure. It looks like there should, on paper at least, be room for 4 boards. Just want to make sure that this is the case before I get too far ahead of myself. Thanks!

    TSS80P soldering pen

    My 14 year old weller iron finally bit the dust the other night, which is a pretty good run for a $20 tool that I bought at radio shack. I don't have a permanent work bench set up in my apartment, so a nice station isn't super convenient. After hearing some positive reviews on the forum about...

    Shielded i/o wire Q

    Hi folks, When using RG147 coaxial as for I/O wiring, I've seen it recommended quite often to only connect one end of the shielding to ground, but not the other. I'm curious as to the theory/science behind this—can anyone explain the reasoning? So in practice, say I've got a mono input jack...

    Silicone housing

    Dang, this stuff is floppy... I ordered some hookup wire from prime without paying too much attention and it looks like I'm going to have a lot of rubbery wires boppin' around my pedals for a while.

    Maratac Hobby Hands

    I've not used one personally, but the maratac stuff tends to be decent quality. Might be something you could find under a different brand for a bit less? Anyway, they seem well liked and definitely a step up from the 'sad robot with hook hands' mag glass/alligator clip style...
