Here is my version of this Screamer designed for SMD technology. Pots and switch are on the other side of Pcb, DC jack and input/output jacks are mounted directly on 1590A housing.

I think the resistor values R10 and R11 must be swapped (R10=1k, R11=220). You can once again verify the original TS MINI?

I don't think so.

Thanks for the answer.
Strange that the developers have swapped value resistors. Here for example the old original scheme.
See R108 = 220 (for tone) and R111=1k

This is a thread I missed completely. Thanks Apollo! Also thanks Ixide for noticing this error. Makes one wonder if someone made a f-up with the BOM.

Hi everyone, maybe somebody knows where i can find a tone knob replacement for the tube screamer mini?

thanks very much

I think you will find there is no Knob as such, the shaft is the knob. So if it's broken/damgaed then you will have to replace the whole pot.

hi Phil thank you very much for your response. Any place where i cand find that exact pot? in the piece it says GC203W and it has the brand ALPS on it. I did try to google it and search for it in the alps web but didn´t have any luck.

thank you

Any one knows something about it?

thanks

It's a 20K pot made by Alps.

Check Digi-key or Mouser for mini pots like that, standard PC mount.
