Ibanez TS9 without output buffer
With switch to change between symmetrical and asymmetrical clipping.

Maxon / Ibanez SD9 Sonic Distortion
This is an awkward one to do a layout for because there seems to be so many schematics out there that the best one is always going to be a matter of personal preference. The original used one half of the opamp for the effect, and the other half for the bypass buffer, with a … Read more
Rothwell Love Squeeze
You don’t come across this very often, but this is a fairly original compressor! At 22 columns wide it will fit in a 1590B, but file the sides down as much as possible for extra space, and maybe use some electricians tape on either side of the box for insulation as a precaution. I tried … Read more
Mad Professor Deep Blue Delay
Slightly modified to give you an overall volume control but if you want the standard unit, just swap the 5K1 Volume 1 resistor for a 12K and solder between IC1 pins 6 and 7. Again it’s small enough to fit in a 1590B with some careful measuring. Updated: Delay 1 connects to the PT2399 pin … Read more
Klon Centaur
[Updated 4th July 2014 – correction to treble control resistors] Note: A new revision of the Klon layout has been done which is smaller and makes better use of the space, so if you want to build this I’d suggest using that layout instead which will also be easier to fit in a 1590B for … Read more
John Hollis Flatline Compressor
Not much has been said about the circuit from the creator who just simply links to the schematic on his website, but here is a great descriptions from Floris: The Flatline compressor is basically a non-inverting amplifier around a opamp. The optocoupler together with the gain resistors determine the total gain of the circuit. The … Read more
Sola Sound Tone Bender Professional MKII
This really doesn’t need an introduction, one of the most iconic and important effect pedals to have ever been produced and an essential part of Jimmy Page’s tone on at least a couple of well known Led Zeppelin albums. If you don’t have one then just build it. Get a measured set of PNP germanium … Read more
Marshall Supa Fuzz
Made for Marshall by Sola Sound this is essentially a slightly modified Tone Bender MkII. Fuzz Central state: The only differences between the two: the input capacitor is 10µF instead of 5µF, the bypass capacitor on the “attack” pot is 10µF instead of 5µF, Q2’s collector resistor is 47K instead of 100K, the resistor from … Read more
DAM Meathead with switchable caps
This was a request from one of our members. I wondered what the best method would be to do this, maybe using a 3 position 4 pole rotary switch, but I think this method by far gives you the most versatility. With both 3 position switches in the centre off position, the Meathead stock values … Read more
