Built this week and it's a monster. A few minor errors on the layout though:
1. The bottom leg of the 10k resistor in the Tone Reaper circuit (column 20) inserts on the 9v rail. It should insert on the ground rail. Using the layout board grid, you would move the leg from P20 to O20.
2. Diodes are labeled wrong. Should be as follows: D1-D2: Germanium D3: 1N4148 D4-D7: 3mm red LED's D8: 1N5187
3. The low pass filter cap on the Tone Reaper circuit, column 22 with legs on row O and row Q, is listed at 47p. Original circuit is 100p. Probably doesn't make much difference.
4. There's a 47p cap on the Octave circuit that looks lost, row 8. It's not on the original circuit and it it bridges the 9v rail and ground rail AA and AB. Not sure what it does or why it's there.
Hoof and Tone Reaper working fine. Octave, well, Q8 and Q9 are reversed, you need to flip both 180 degrees. If you don't want the octave control, you'll need:
Remove: Q7 100nf and 1uf caps under Q8 1m resistor to the right of Q7 1k resistor to the left of Q7 10k resistor from Z9 to AC 9
ADD Link from AC4 to Z4 47K resistor from X16 to AB16 (ground), tight fit
Swap 1m resistor on AC5-AC8 with a 2,2m one.
Both if you want the octave control or not, don't forget to flip 180 degrees Q8 and Q9.
I own this pedal, it was one of the first I ever purchased and I'm still tempted to build this for the octave control.
ReplyDeleteyo, can someone verify?

Thanks for a great layout and happy building!
WOW!
DeleteVery cool.
The layout is updated and TAGGED!

Enjoy, this pedal is a dream come true!
