Don't choose... build both. It's easy?

Peter Michaux	Don't choose... build both. It's easy? I've been pooring over the schematics for the Dual Rectifier all day. If you ignore the clean version of the orange channel there is very little difference between the orange and red channels. I think that with one triple pole triple throw switch you could have a single channel amp that could be switched from red to orange. The only differences I can see between normal orange and normal red are 1)the capacitor at the top of the tone stack (this could switch between 680 and 600 pf) 2)the red presence knob (this could switch from the red presence pot to a 10K resistor) and 3) and LDR 19 (feedback) (this could switch between open or closed.) However, you would need to keep both the orange and red channel presence pots to keep things this simple. You could get a stacked double 25K pot so that there is only one presence knob for the user. By making the amp one channel and ignoring the clean orange mode the complex switching disappears. The more I think about this the more I might end up doing it. Instead of choosing red or orange I think it is better to build both channels when a TPTT switch and a stacked pot are the only differences. I am a fairly new to this whole amp business as you may know but I think I understand this one alright. If someone checks out my idea I'd like to know if I'm right or wrong. Peter PS Where is the "B" side of "V1"? it looks like it is doing nothing to me.

I think that with one triple pole triple throw switch you could have a single channel amp that could be switched from red to orange. The only differences I can see between normal orange and normal red are

1)the capacitor at the top of the tone stack (this could switch between 680 and 600 pf)

2)the red presence knob (this could switch from the red presence pot to a 10K resistor) and

3) and LDR 19 (feedback) (this could switch between open or closed.)
