King Tone The Soloist

 Requested quite a few times. Clémtent got hold of one for a repair and while he was at it he traced it and drew a schematic. He even built a clone and it sounds spot on.

Note that both 220nF caps are tantalums in the real units but film caps will sound identical.

    Hey Anders what about a Silvertone or Valco emulator like the Twin Twelve? Love that greasy tweed sound. But want more!!!

      You might want to check out De Stijl, an old DIY design which was cloned by JHS.

      I have yet to do a layout of the Supro emulator, Supreux Deux...

    Yeah thanks man. I’ve def come across this one before. I’ll check it out once I find the volt doubler. Btw love the D*A*M stuff. Tried the Meathead and the Fuzzrong. What are some of their greatest hits?

      Meathead of course. But I also have a soft spot for the Grease Box variations and the Super Bee!

    Verified sounds good with red leds instead of BA282

    may i ask what the W stands for for the tone pot? 25kW?

    They’re basically an A taper and a C taper together. They’ve become a pain to find. Usually B pots will work okay until you find the right kind. Maybe you’ll have better luck locating them.

      I bet a 20kW pot would work, these are pretty common...

      Sure, 20kW is what I use and the range is still very large. B taper will work of course but 90% of the tonal difference will be at the extreme sides of the pot. Almost no difference from 20 to 80 %.

    Check 3Tone-R9-R7, there are two resistors on the PCB board, here one and completely different.

      Hmm, which PCB should I check out? The layout matches a schematic that was traced from a real unit.

      On the PedalPCB picture, from 3 Tones there are other resistors. I misunderstood the designations of the resistors? From 3 Tone you have 1k resistor to IC-6 pin. I made a layout according to their picture and did not understand why the difference. Sorry if so. https://www.dropbox.com/s/wix2kc3ilx9w75g/1King%20Tone%20Soloist111.jpg?dl=0

      PedalPCB used the String Singer side of the Duellist for his PCB. I used a Soloist which is not exactly the same.
      The Duellist switch is FAT/STOCK/GLASS.
      The Soloist switch is GLASS/STOCK/EDGE.
      This is why you can find differences.
      And I can confirm that this layout is strickly correct if you want to get the Soloist sound. I've had an original unit to compare and they sound the same.

    Can you post the schematic?

      Just like to say, I love these layouts. I built this and the purple plexi, both pedals are awsome!!! Thanks for your work.
