Earthquaker Devices Palisades
The mother of all TS808 derivatives/variants, the Palisades incorporates just about every mod to the classic Tube Screamer circuit. Two rotary switches control the bass response (Bandwidth) and clipping (Voice), one toggle bypasses the input buffer while the other is a bright switch, a footswitch selects between 2 separate gain pots, and with an added … Read more
VFE Pedals Dragon Hound
“The DRAGON HOUND is a dual overdrive + distortion pedal that combines the core circuits from the Alpha Dog and Pale Horse into one unique dirt box. Each circuit has a dedicated drive control, and the blend control can dial in saturated distortion tones that retain the clarity of an overdrive.“ You can find their … Read more
Landgraff Dynamic Overdrive/Clay Jones Overdrive
Probably two of the most hyped Tube Screamer clones around. The only real difference between the Dynamic Overdrive and a TS808 is the clipping switch, offering symmetrical red LEDs, diode lift, and asymmetrical silicon diodes. The Clay Jones Overdrive is mostly the same, just without the clipping switch (just LEDs), and a Burr Brown OPA2134 … Read more
Friedman Dirty Shirley
Original info: “The Friedman Dirty Shirley all-tube amp is well known for being one of the most flexible and touch-responsive single-channel amplifiers on the market. Now you can get that same tonal versatility, sensitivity and harmonically rich overdrive in a pedal. The Dirty Shirley Overdrive packs the same intuitive control set as the amplifier, allowing … Read more
EarthQuaker Devices Palisades
Original info: “The Palisades is something we said we would never do… an overdrive based on the legendary TS808! Gasp! The horror! Another tubes creamer?? In 2014?? Really?? After loads of requests we finally buckled. We ran tests with every popular clone on the market as well as several vintage originals, compared, contrasted and took … Read more
JHS Twin Twelve V1
From the source: The JHS Twin Twelve is the first effects pedal to go after the sound of the short-lived but revered Silvertone 1484 Twin Twelve. Available through the Sears catalog from 1963 – 1967, the Twin Twelve was not regarded in its day as a premier amplifier. However, modern players looking for a vintage … Read more
Way Huge Purple Platypus
Here’s a bit of a rarer old school Way Huge circuit from the 90s. It’s essentially what would happen if a Red Llama and a Foxx Tone Machine had a baby. Original thread on FSB here with schematic.
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
Lumpy’s Tone Shop Lemon Drop/ZII/Series 7
Here’s a simple little overdrive designed to emulate the old Vox 4 and 7 series amps (used by the likes of Jimmy Page and the Beatles). Pots are board mounted and it should fit in a 1590B easily. I’ve added a trimmer to bias the JFET at little easier. Schematic and voltages can be found … Read more
