Check before you build · 4 values the reader of this schematic was not sure of
- R6: label hard to read (could be R6 or Rb), value 2.2M is clear
- LDR-1 VOL.: duplicates LDR1's name on the drawing; probably LDR2
- S2/S3: switch type inferred from the pin numbering, not written
- Wah Travel 400K pot has no designator
