Mad Professor Simble

This is been traced for a few weeks now over on FSB and I've meant to lay it out since then, but just now getting around to it. If you don't know, it's an amp-in-a-box type trying to emulate a Dumble amp. Apparently it sounds very good with smaller amps. Should fit nicely in a 1590B with board mounted pots as per usual.

  3. I can't believe I missed this one.
    Very nice sounding pedal.
    I used an LM833 instead of the TLC2272

  6. I also made it with LM833. Very good pedal. Somehow similar to a Zendrive. I made it in one box with an Orange Squeezer with external Compression pot. This Simble just loves the squeezer. Seriosly, if you are a strat blues player these two are all what you need.

  7. Hello, I'm note sure I'm reading good about 2 values. On the circuit I'm hesitating between 8.2nf and 82 nf for a capa. and between 2.2 M and 22M for a resistor. Can somebody confirm please.
