  1. Is there a picture With a higher Resolution for this one? I would really Like to build it but its very hard to identify all parts

  3. Are you sure this one is already verified? I found a schematic for this one and at least there are some differences in parts. Unfortunately i am Not good in Reading schematics yet but one difference would be that the 47uf might be 47nf due to my schematic

    2. Yes, it is verified, 47uf is typos. Should be 47nF and it is 14 cuts not 16.
      Thanks for spotting this, not sure what happened to this one.
      It will take a few days until I can correct this one.

    3. Wasn't happy with the old layout so I tweaked my Foxx Tone Machine layout which this is based on. It has better symmetry and the caps connecting to the tone switch is now on the board.
      Tone Machine layout is verified but I've marked this one unverified just in case but since they're nearly identical it shouldn't be any problem....

  4. I finished my build and you're right, its verified.
    The octave is a little quite, or its better to say it is depending to the guitar Output. Humbuckers or active guitars does have a Lot more present octave Sounds. If you Stack the Pedal its very present and great. The Drive itself Sounds great. The dpdt Switch is an on/on. I tried on/Off/on First but that Acted very strange in middle position.
    I used a dpdt Footswitch Switch for the octave on/Off wired Like this:

    1 4
    2 5
    3 6

    1-octave Switch 1
    2-octave Switch 2
    4-led ground/cathode
    5-ground

    Led plus/Anode to 4,7k to dc

    Hope it will fit in 1590bb because my offboard wiring is Always messy as fuck

  5. IT's verified, indeed. Build it and sounds great.

  6. I think the 2 elec caps on c and e of Q2 are backwards, according to the schematic.
