The classic ’70s overdrive by MXR, and is essentially the same as the DOD 250 and Ross Distortion. I designed the layout to have onboard pots, to alleviate some offboard wiring. It also has the LED resistor on the board, again to reduce offboard wiring a bit. It’ll fit perfectly in a 1590B enclosure. Might … Read more
From Fuzz Central, this is a modified Dallas Rangemaster treble booster. Uses an NPN germanium transistor so you can daisy chain it with other pedals that run off a positive 9 volt supply.

Basic info about a Madbean original: The BaconBits Booster is a simple op-amp based booster powered off a split rail supply. It can be used as a stand-alone boost to drive the front end of a tube amp or another effect such as an overdrive. The BaconBits utilizes an input buffer which feeds into a … Read more
There’s very little point in building a 1:1 clone, as you can score the original unit for peanuts as used. Possibly even cheaper than what the parts alone would cost you to build one. But instead of going through a painful bypass operation on a Boss box and having your way with the circuit, you … Read more
Request. Everyone knows what it is so I’ll leave the description to Mike Matthews: The NYC original. Hendrix and Santana were among the first to get a piece of the Pi, and for over 40 years the Big Muff Pi has been defining the sound of rock guitar. Revered by contemporary guitarists and rock legends … Read more
Slightly modernized layout for a forgotten classic. Transistor pinout is per the transistors you most likely have already. Original has C369s, which are rare and have a different pinout. There’s added series polarity protection and for the clipping diodes, you may use what you like the best. Schematic i have doesn’t specify which are used … Read more
Request. This is based around the Runoffgroove LM386 Ruby, but with an IC preamp, into a 12AX7 section, and then into the LM386-N3 power section. Sounds pretty good in the clips which you can hear at: http://www.sophtamps.ca/mambo/index.php?option=com_content&task=view&id=28&Itemid=39 This needs a 12VDC supply, so if you’re using an unregulated one like the one mentioned in the … Read more
Wanted to do a quickie, so this seemed like a suitable circuit and we didn’t have it on the library yet. Not a lot of info around.. One could play around with the value of that 10µ cap to see how 22µ or even a 100µ affects the tone. Maybe even make it switchable. Either … Read more
Ran into a schematic of a preamp on-board circuit found in Blade brand guitars. The original called for LM4580 dual opamp, other channel unused. So i drew this layout for a single channel chip and added volume control, power filtering etc. You could try on a number of single opamps to see which sounds best … Read more
