What do the DIP switches do in a Teese wah?

[Craig V]

I've been studying wah pedals for a while trying to come up with the ultimate wah design.  I was curious what these do electronically?  They look like they connect resistors into the circuit.  I found a pic from an ebay auction.

I'm not trying to clone an RMC3 or anything or asking for the schematic to it.  This just looks like a very versitile feature that I might want to include in my wah board.

Thanks.

Looks like they make up the bandwidth/sweep control - I pasted the details below, but all controls are explained here:
http://www.realmccoycustom.com/RMC3TUNING.htm

"The 9-pole DIP switch expands or compresses the SWEEP (frequency range) of the RMC3.  The switches are set up in a sonic progression covering 9 octaves.  Switch #2 equals the sonic range of switch #1 AND the max (9:00) FINE TUNE adjustments.  Switch #3 is the sonic equal of switch #2 PLUS switch #1 AND the max (9:00) FINE TUNE adjustments...and so on.  This overlapping stair step sequence lets you select the depth and width of the pedal's actual frequency sweep.  The higher the number switch(es) selected, the wider and deeper the sweep will be."

Hope that helps
