This is a library of perfboard and single-sided PCB effect layouts for guitar and bass. I'm not an electrical engineer by any stretch of the imagination, just a DIY'er who likes drawing layouts. It is meant for the hobbyist (so commercial use of any of these layout is not allowed without permission) and as a way to give back to the online DIY community.
The Tenebrion was designed by CultureJam and is the further development of the Box of Hall reverb. It uses the Belton BTDR-2 reverb brick, which I've designed to fit on the solder-side of the circuit board. You should be able to squeeze it into a 1590B.
Here's a great optical tremolo designed by CultureJam. Schematic can be found here. D1 is the external rate indicator and could be used as the on/off indicator as well. Just use part one pole of your 3PDT to break/connect one of the leads of D1. D2 and the LDR should be isolated together (heat shrink tubing works great). Tayda LDRs and either orange or red LEDs seem to work well in this circuit. A NSL32-SR3 optocoupler works well too.
This was a originally an SMD 2-in-1 board CultureJam put out. On one side was a Fuzz Face and the other this Tone Bender. So I figured they'd be good Fuzz Friday layouts. They're not on the same board, but either one should fit in a 1590A.
For Fuzz Friday, here's another one from CultureJam.
The Stein Fuzz is a lightly modified version of the Roger Mayer Stone Fuzz* pedal (which is itself a lightly
modified Fuzz Face). The main difference is more standardized part values (the pots mainly).
It's meant to be a positive ground circuit (center positive, so not daisy chain-able with standard center negative/negative ground effects), but looks like a good candidate to convert to negative ground. The perf side of the layout below reflects the positive ground orientation of parts, and the PCB side reflects negative ground.
Here's a cool vibrato effect designed by CultureJam and based on Tim Escobedo's Wobbletron. Here's what he had to say about it his original build doc.
The DuoVibe is a two-stage optical vibe circuit than can also cop subtle phaser tones.
The LFO is modified from the Shoot the Moon tremolo (itself derivative of the
Tremulus Lune) and is capable of triangle wave and near-square wave output. The
pitch bend in Vibe mode is discernible but not capable of “seasick” wobble. With the
depth cranked, you can think of it as a sort of “tremolo with funk going on” kind of
thing.
There is a Vibe/Phase Mode switch, the name of which indicates its function and
purpose. This switch simply toggles a feedback filtering cap value, but is useful
despite the simplicity.
Here's nice delay from CultureJam. It's based on the Rebote 2.5 delay and has a lot in common with many other PT2399 delays. However...
The Triton, diverges from the base concept by adding a second Delay Time
potentiometer and a unique (in the DIY world) modulation effect. The Delay pots are
selectable via footswitch (latching), and when switching from one time setting to the
other, the delay time change happens slowly, just as if you were manually turning
the delay time pot on a standard delay pedal. This causes a gradual pitch bend that
slowly resolves to unison if a note or chord is struck and held when toggling
between Delay pots.
To control the speed of the pitch bend/resolve, there is a pot labelled “Slow”. Making
the transition speed slower also makes overall delay time longer.
This is version 3.1 of the Triton, and includes all controls externally (the original PCB by Pickdropper had the Tone pot as a trimmer). Here's the schematic for reference, and the demo below is of an older version, but you get the idea.
In case it's not clear in the layout, the Time Switch is the 2nd footswitch.
Here's a great sounding reverb designed by CultureJam, built around the typical Belton BTDR-2 reverb brick. I've laid it out for onboard pots and the BTDR-2 being mounted from the solder-side of the board.
The Ersatz Verben is a pseudo-reverb circuit using a PT2399 for short slapback delay. It was designed by FSB member CultureJam and refined by EarthTones, and based on the Crap-Fi Delay by Allesz. Delay time ranges from 40-140ms. I've laid it out for onboard pots and added polarity protection and an onboard LED resistor. Here's a demo:
