JHS Little Black Buffer
Here’s a simple buffer from JHS. It really only uses one side of the opamp (why not just use a TL071?) and the extra resistors on the other side are just to meet the manufacture’s specs for an unused side. I couldn’t find a schematic for this one, but drew one up from lvlark’s vero … Read more
Madbean Shortstack Overdrive
Noticed frank had posted this in response to someones questions about the bluesberry mod for the hotcake. When i compared the schematic to the hotcake i noticed a few differences so I thought it would be a nice addition and variation to have on the site. The only addition to the schematic I mad is … Read more

DEADplate – “five to nine” – Practise and recording amp
If you’re looking for a five to nine watt practise and recording amplifier – build this, it sounds great and only uses two valves! It’s got a special mosfet based phase splitter design which I’ve not seen anywhere before – so I’m claiming my design is unique 🙂 Build it and leave your comments below.
D*A*M Drag’n’Fly
For #FuzzFriday, here’s another D*A*M Fuzz Face variant, the Drag’n’Fly. This one is a silicon/germanium hybrid, using a BC337 silicon transistor for Q1 and a CV7112 germanium transistor for Q2 (but feel free to experiment with other transistors). I’ve laid this out for board mounted pots and the enclosure drilling template can be found here.

Zinky True Grit
Here is an overdrive pedal by Bruce Zinky, the creator of Smokey Amps. Not great videos available at the moment.
Run Off Groove Tube Reamer
Here’s a simplified Tube Screamer circuit from Run Off Groove, the Tube Reamer. Basically, it’s a buffer-less TS without the tone control. The IC can be just about any dual op-amp. JRC4558 or TL072 are good places to start. Should be a great candidate for a 1590a build. For more info, schematic, and demo see … Read more
