The switches can be by passed, but you will have to decide on a setting for each one and have the circuit hard wired to those settings. The Depth/Frequency/Q work together, hard wiring the Depth to value 1 completely bypasses Frequency/Q so those two switches would not be in circuit.Taking a pair of Opals to Wilkinsons on Thursday to find out why one of them keeps buzzin loudly on turn on & getting louder if left powered up.
Also going to ask if it's possible to isolate the switches from the amps & drivers to remove the risk of issues that seem to be caused by the switches.
Watch this space
It may be possible to completely bypass the contour boards and take stock values straight to the amps, but looking at the number of parts on the boards, that's a complex task to try and fathom.
