Re: Relay switching?

I think I might go for that. I've seen the schematics for how to wire this...but I'm still not sure about it.. The coil gets 6.3V (or whatever voltage it needs) to open/close the relay, I get that. Does the relay open/close when the foot switch connects the coil to ground, or lifts if from ground? T...

Post OD tonestack?

Re: Reverb - A -Loop Schematic

Ok.. nice. Is placing the reverb circuit with the dumbleator a better way of doing it than the normal placement, or is it just to make it convenient with the two circuits in the same chassis? I have a schematic I made (with some assistance) that has a built in dumbleator between the preamp/OD and po...

Relay switching?

I can't decide on what kind of switching to use. some say that relays can make popping sounds, especially if there is a spring reverb in the circuit. Some say that optocouplers is the way to go, and others say analog switches should be used. To me, relays sounds like the easiest way.. Weber even sel...

Stupid question maybe...but

I see that the bottom part is the reverb circuit.. But what is the upper part? Is it the dumleator, or is the whole thing for the reverb?

I wondered since there is an input, then a send and return, and then an output, in addition the the reverb part..
