Wampler Pantheon
The Pantheon is Brian Wampler’s take on the classic Bluesbreaker circuit. It adds some of the mods from the King of Tone as well as a Baxendall tone stack for the Bass control (the would be treble control of the Baxendall is fixed) and a gain switch to set different min/max settings of the Drive … Read more
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 toggles for Presence and EQ (mids). Should be able to squeeze it into a 1590B.
Wampler Hot Wired V1
The Hot Wired is a dual channel dirt box offering distortion and overdrive modeled after the tones used by Nashville session artist Brent Mason. I’ve laid it out for board mounted pots with the board mounted vertically in the enclosure. I laid it out with a 1590BB in mind, but you might be able to make … Read more
Wampler Hot Wired v.1
Original FSB thread and schematic available here. These are 2 separate effects in one box. Follow Mark’s Dual Offboard Wiring. 23/11/2017 Layout Updated! Added the 2 Inputs caps.
Wampler Tweed ’57
Here’s another (and more complicated) amp emulator, and another great design from Brian Wampler. This one stacks JFET stages much like the Cranked AC. It emulates a dirty Fender tube amp with a 3-band tone stack. I added trimmers so it’s easier to bias the JFETs and it’s laid out for board mounted pots in … Read more
Wampler Sovereign
Here’s another Wampler take on the JFET mu-amp design. This one adds a op amp stage at the output and features a Big Muff-style tone stack. This one’s pretty versatile and a great sounding distortion. Ian sent me his perf layout of this one and I refined it a bit for what you see below, … Read more
Wampler Pinnacle
Got another cascaded JFET design, this time from Wampler. Great for getting those EVH Brown Sound tones. I’ve added 2 trimmers for the 2 non-cascaded JFET stages to make biasing at little easier (originals use 22k resistors). Should be an easy fit in a 125B with top mounted jacks, but should also work in a … Read more
Wampler Velvet Fuzz
The Velvet Fuzz is a unique fuzz that combines amp emulation and 2 different selectable fuzz tones. The toggle selects between a LM386 (Tight) circuit, and a 2N5089 (Big) circuit. These then push a Plexi Drive circuit that gives the Marshall amp emulation. The modular nature of this design gives you the option to have … Read more
Wampler Cranked AC
Another amp emulation overdrive from Wampler that’s supposed to sound like (you guessed it) a cranked Vox. This one has been discontinued, but was very popular. It’s very similar to the Plexi-Drive, but doubles the transistors and there are a few component changes. I’ve added trimmers to help bias the J201s.
