Big Muff mod to switchable silicon/germanium diodes

[JakeAC5253]

I ordered a slew of germanium diodes the other day and within a few weeks I want to begin experimenting with them. I want to keep the silicons in the unit so that I can access the stock circuit if I feel like it, but have the mod switchable. I am experienced with switch wiring, that isn't an issue at all, but I'm a bit curious about one thing. The pedal has two diodes per gain stage which makes for four of each type of diode. Am I limited to using a 4PDT switch for this or can I somehow get away with using a DPDT?

DRIVE: The operational window has been carefully adjusted to set the gain of the silicon 1st stage to drive the treble booster section with clean signal levels that are higher than those obtained from the guitars pickups. When the drive is increased from it's minimum setting the 1st stage will begin to distort and you now are in the new territory of having smooth distortion followed by EQ and then the treble booster section. This area of operation is very useful as the germanium output stage is driven harder. So it is possible to set the DRIVE control to produce clean treble booster action with enhanced drive and EQ or have a combination both silicon and germanium distortion with inter stage EQ.This unique set up gives brand new life and tone variation.

TONE: This controls the inter stage passive equalisation between the 1st stage Silicon Drive section and the final Germanium treble booster section. It has been carefully voiced to give a very musical and useful tool when setting up the final desired tone.

OUTPUT: This controls the final output level, which has enough output level capability to overdrive the 1st stage of the amplifier being used.

I have this one, could that be an idea for you (the potmeter variety)??

It`s a cool sounding pedal, just a booster with the drive set low, and raelly fuzzy with the drive on max
