Channel switching

[makinrose]

I'm currently implementing a switch that will select between an SIR 34 AND 36 mod on a JCM800. SIR 36 adds an extra gain stage. I have it currently on a toggle switch with no relays or anything fancy. Would the the relay kit offered work well with this? I noticed in the picture it has a cliff jack mounted on the board. Is this to plug in a footswitch? Would I be able to incorporate both a toggle switch and footswitch with the kit? So if using a footswitch for example would bypass the toggle switch. And with no foot switch connected I could also use the toggle switch.

I've never implemented anything using relays for switching before and would like to learn about this.

Having worked with the SIR circuits quite a bit I'm not sure making the modes footswitchable would an addition to the circuit unless you had separate gain and master volumes for each mode. The volume would change radically if you just switched out the gain stage. Having those controls with switching certainly is possible if you desired to do that.  

For tone tweaking I found that adding mini-switches to controls voicing options (cathode bypass cap values, attenuator values etc) is good addition to that circuit and gives you lot flexibility in tweaking the voicing to your liking.
