From the post
Another great fuzz pedal from Marc, and I felt a nice one to add to our collection. I thought with 8 transistors this would be a bitch to get into a 1590B as a vero layout, but it turned out pretty comfortable in the end.
Info about the original:
Skreddy Pedals Top Fuel: strikes a balance between high gain, sustaining distortion and articulation.
First, I trim out the woofy, mushy, congested bass. Then amplify (a lot) and distort using mosfet soft clipping (twice), for a fine-toothed, modern, tube-like distortion character. Then trim out the harsh and fizzy high end and use a mid-hump tone stack that's centered around 700Hz.
The string attack is always preserved throughout the entire range of the fretboard, regardless of the sustain level. Tonal emphasis is placed on the midrange in order to showcase the player's technique.
