Do you know what this pedal could be?

I seen some video, and wonder if is original or not.

Huge picture from their site:

YATS = Yet Another Tube Screamer
However, the four diodes (and description on website of "dual clipping stages") suggests it's not just a TS clone with added bass control and mid shift switch.

Interesting... seem a bit expensive for a modded TS

Like a Landgraff.

Anyway, this is a more recent design:

Kingtone manufacture their own potentiometers ???

Drive, Bass, Treble, Volume...has to be a Timmy clone

Blues Power schematic:

Note the Q1 transistor with all three legs connected to ground... it's a decoy to throw us gut-peepers off the trail that it's a Timmy. Pics on the tracing journal to satisfy anyone's curiosity. The four diodes in the second stage also almost certainly do nothing since it's a unity-gain stage and there's no signal to clip after the first stage.

unless I've missed something, IC1B looks very much like a textbook non-inverting amplifier with a gain of 2 (6dB) plus a low pass cap and some feedback diodes.

it will double and then clip the signal present at the positive input (IC1A output minus some highs because of the treble control) down to +/- two diode drops (~2.4Vpp), while also passing a unity copy of the input, since it is a soft clipping stage.

Yeah, you may be right. I was thinking in terms of inverting but yeah, noninverting is 1+1, so 2 and not unity.

I'd still be very surprised if the diodes did much, but if there's a gain of 2 then there technically could be a little bit of signal to clip. If someone wanted to sim it to see for sure, I'd add it to the tracing journal with credit.
