The Fuzztone is an early design of Dan Coggins before Lovetone or Dinosaural appeared. The first publication in ETI (Electronics Today International magazine) actually had an error on the schematic – it wasn’t critical, as it just changed the frequency response a little, and it lost some level along the way in the filter … Read more
A nice booster from Thorpy, most likely Dan Coggins design. The build notes from PedalPCB suggest germanium diodes across the opamp for a dirty boost. Schematic can be found here THORPY HEAVY WATER BOOSTER – VERO LAYOUT This puts out a lot of level, and the low cut can put it in treble boost territory on … Read more
Another day, another compressor layout… This is a Dan Coggins design, the Dinosaural OCT-201 Opticompressor, and the predecessor to the Thorpy Fat General, which was also designed by Dan. Not many of these are around, as it was only made in a short run. Schematic and tracing journal on Aion FX. DINOSAURAL OCT-201 OPTICOMPRESSOR – VERO … Read more
While on a run of compressors, I thought this one looked interesting. ThorpyFX Fat General is an optical compressor with a treble control and a blend function. Schematic can be found on PedalPcb here. It’s said to be a progression of the Dan Coggins designed Lovetone OCT-201 – based on the trace at Aion FX, … Read more
The Dinosaural OPA-101 Overdirven preamp is a variation (or improvement) on the Dinosaural Tube Bender. This is has the tone control like the the Aion FX version, but I did leave the output stage as a buffer as per the original. The filter itself is on the original which you can see on the schematic … Read more
While I’m doing Lovetone, I have to do a Big Cheese… this is now the predecessor to the Thorpy Field Marshal Fuzz, now that Dan Coggins is helping out on the design side of things there. The schematic can be found at Aion Fx, and this version includes a bit of extra boost at the … Read more
Lovetone effects pedals are pretty legendary, and I have meaning to get around to some layouts for a while now. I thought I might start with the Brown Sauce, which is the least challenging. You can find the schematic here on Aion FX – also check out the rest of the Lovetone line that they’ve traced too, as … Read more
There has been several schematics of this one over the years, each one having some bugs. But recentrly Lacesensor at FSB managed to do a proper trace and he posted thr corretions at FSB.
Designed by Dan Coggins (Lovetone and Dinosaural). Despite its name it is more like an overdrive with asymmetric soft clipping and a tone control that pans between a low pass filter and a voltage divider.
Just traced by Aion Fx as their Ixuea project. This layout is slightly modified compared to the original pedal. First, stock units had a fixed low pass filter before the volume control. The resistor in the filter is now replaced by an external tone control. Secomd, it is wired for true bypass with the input … Read more
