I guess this should be posted here as well. My take on the TS clipping amp with some changes. Brief description and some discussion at FSB.. Due to nature of relatively high gain and the input buffer design, i recommend using a switching jack that'll ground the input jack tip when plug is not present. Currently, the squeel when nothing in the input jack is the only downside to this circuit i'm aware of. And yes. It sounds pretty damn good. Sort of like a sleekier bastard son of Clark Gainster and vintage TS808.
This also utilizes the SIP opamps some of you may already have laying around.
...and here's another version of the same circuit that uses way more common DIP opamp. While the chip initally was 4558, you should try on what you want. I bet it'll sound good with LF353, OPA2604, AD712, NE5532, etc. DIP layout is currently unverfied... verified too.
