Super 6G4A speed Pot

[sam]

Greetings,
Planning a 6G4A build. Anyone who has built this circuit what did you do about the 4M-RA pot for vibrato speed. Can't seem to find that resistance. Did you use a 3M-RA? or some other substitute. Suggestions welcomed.

The 3M-RA will be fine. Speed just won't go quite as slow, but that can be compensated by using larger caps in the feedback circuit.

I'll do that. Thank you for your quick response.
