Rothwell Love Squeeze
Here's a nice little compressor that should be a fairly easy build. It doesn't have the squish of a DynaComp, but goes for a more subtle compression like the Orange Squeezer. Board mounted pots and an...

MI Audio Boost 'n' Buff V1
The Boost 'n' Buff is a simple little booster that doubles as a buffer when it's turned off (so it's not a true bypass effect). You should be able to squeeze this one in a 1590A. The FSw pads are for...

Basic Audio Zippy
The Zippy is a silicon fuzz designed to give that vintage brassy sound. I've laid it out for board mounted pots and it'll fit in a 1590B or a 125B with top mount jacks. In the words of John...

Green Citrus
Here's a cool DIY design of a Green (Mutamp) amp emulator. Four JFET stages with a 2-band EQ and a Boost control. Should be a nice easy fit in a 125B with the board mounted pots. Here's the schematic...

Wampler Paisley Drive
Got a request for this one. Another take on the classic Tube Screamer built for Brad Paisley. The traditional input/output buffers have been swapped out for JFET-based buffers, and there are two...

SoulSonic FX Chalice
Here's an other heavy one. This one was designed by Martin (aka soulsonic) and is basically 3 transistor stages and a tone stack into a JFET gain recovery stage. The toggle switch selects between...

EarthQuaker Devices Erupter
Merry Fuzz Friday, everyone! Here's EQD's latest fuzz offering, the Erupter. Essentially it's a JFET buffer into a pickup sim (the transformer) into a Fuzz Face-esque circuit. The Bias control controls...

Devi Ever Ruiner
Another brutal fuzz machine from Devi, and sounds great on bass and guitar. Pretty straight forward design–two cascaded transistor amplifier stages with a pre-gain control (intensity) and standard...

Rockett Animal
Another fun overdrive from Rockett, this time going for a Plexi sound. Think of it as the first half of a buffer-less Tube Screamer with an AMZ Stupidly Wonderful Tone Control 2. Here's the schematic...

Earthquaker Devices Disaster Transport Jr.
Here's EQD's take on PT2399 delay. The most unique thing about it probably the use of a Big Muff-like tone stack. It will definitely fit best in a 125B with the board mounted pots, but if you use long...

Ross Compressor
Somehow I've not laid this classic out already, so here's the Ross Compressor. One of the most highly thought of (and therefore copied) compressors of all time. Should be an easy fit in a 1590B.

DBA Octave Clang
For Fuzz Friday here's the Octave Clang from Death By Audio. It's a transformer based octave fuzz utilizing a 741 opamp. Fairly low parts count and should fit in a 1590B.

Run Off Groove Azabache
Not sure how/why I avoided laying this one out for so long. The Azabache is a great sounding overdrive that emulates classic Fender amps. Check out the ROG article on the circuit for more info,...

AnalogMan Prince of Tone
Wanted to redo my old layout with board mounted pots. I've laid it out with the Presence control externally and the diodes on a DIP switch, though you could easily wire up an external toggle if you...

Earthquaker Devices Westwood
For the blog's 600th layout, here's a new one that didn't take long to get traced. Here's EQD's newest offering, the Westwood Translucent Drive Manipulator. Great for pushing your amp and giving a near...

SolidGoldFx If 6 Was 9
Happy Fuzz Friday, everyone! Here's a nice little modded Fuzz Face from SolidGoldFx. The switch selects between input caps and the Bias pot adjusts the voltages to Q2. Other transistors can be used...

Electro Harmonix LPB-1
Got a request to redo the LPB-1 with the pot board mounted. Can't say I'm opposed and it only took about 5 min to layout. :) Easy fit in a 1590A. If you want to make the Screaming Bird treble booster,...

Fenrir Distortion
Came across this schematic over on the Tagboard Forum and thought it'd be a good addition here. Heavy distortion tones on tap with some clipping options and a full 3-band EQ. Switch is a SPDT on/on.

Run Off Groove Uno
I know I've mentioned this to a few people over the past year probably, but I've finally been able to get it edited. That's right, here's my tutorial on how I layout circuits in DIYLC... the first...

DOD Carcosa
Happy Fuzz Friday, everybody! Here's a new fuzz circuit from DOD. It's a cascaded transistor design offering a wide range of tones with tons of output. Should be an easy fit in a 1590B.
