NOTE: 220 ohm resistor R9.5 was omitted from the schematic. It should appear between the TONE pot wiper and Tantalum capacitor C8.

NOTE: The pin identification numbers for IC1 in the schematic are reversed. IC1a should have the inverting input labeled as pin 6, the non-inverting input as pin 5 and the output as pin 7. IC1b should have the inverting input labeled as pin 2, the non-inverting input as pin 3 and the output as pin 1.

5-Knob Compressor PCB Rev. 2.0

I ran into some discrepancies between the schematic and the PCB that still need to be resolved. Specifically diode D4 appears to be backwards on the PCB when compared to the schematic which Keith tells me is correct.
EDIT: This diode error has been corrected on Rev 2.1 boards.

According to the schematic capacitor C3 should be a 10uf and not a 1uf. There also seems to be a bit of confusion about resistor R29. The PCB is marked 27K while the schematic says it should be 10K. The positions of C22 and R27 on the schematic should be flip flopped. Keith informed me he would be making the necessary corrections.

Parametric EQ

PEQ Fix

Keith has found an error on the PEQ PCB that can be easily fixed. Resistor R49 (100K) is on the wrong side of capacitor C18. Currently the resistor is connected to the plus lead of the capacitor. The other end goes to ground. The resistor should be connected to the negative lead as it shown in the schematic. To correct this error remove R49. You can either apply heat to it and pull it from the board or snip the lead ends with wire cutters. Now take another 100K resistor and solder it across lugs 2&7 of the stomp switch. Another option would be to solder the resistor to eyelets 2&7 where the stomp switch header would have been.
