The Pete Cornish SS-3 is one of my favourite overdrives – so I thought I might make another one with a different layout and buffer. Changes Swapped the Cornish buffer for a standard opamp based buffer Ran the reference voltage through the spare opamp Used a quad opamp instead of 2 x single op amps … Read more
Based on the Green Citrus Matamp amp emulator circuit but it have enough value changes to warrant its own layout. Based on a schematic from Dead End Fx.
Time to dust off the depletion mode MOSFETs in the bin. Here is a quite interesting design using four of these overlooked transistors. It is basically Plexi voiced a low to medium gain overdrive with a James tonestack. Each MOSFET have a3,3k resistors at its Source and according to the schematic these should be adjusted … Read more
Here is a very interesting and not overly complicated PT2399 based circuit from Bluff Chill Devices. It is an “envelope modulated delay” which sort of emulates a worn out tape delay. This layout is for V1 only but there is two layouts; one for stock 2 knob version and one modified 4 knob version. See … Read more
The Grand Orbiter Phase Machine is a four-stage OTA phaser, with options for vibrato or phasing (a bit like a Univibe). Not exactly a small board, but not too much to take on either. MLC caps might be a good idea for some of the 1uf caps to save space. Currently unverified. I have reviewed the … Read more
