Aug 17, 2025 · Now you've got me wanting to develop a five knob percolator: input, output, pre-bass, post-treble, and a splat or clipping symmetry control. 7kΩ resistor in series with one of the clipping diodes to produce asymmetrical clipping. Handbuilt effects pedals from the quaint industrial hearland of Luton, England. I'll throw an extra mosfet boost in front so you can make it cave in completely. Its toggle switch controls the amount of bass at the input stage. Reducing or, ideally, eliminating the resistor makes the lower octave more prominent.
