Clean and Dirty switch in Single Channel Amp?

[melvinbrinson]

Has anyone ever modded, rigged hardwired their amp head for clean and dirty channels with a single channel amp head? If so, I'd love to hear how this could be done.

Thanks in advance

Easy as a pie, MANY amps are like that (mine included).

That is good news! Would you happen to have instructions on how you did it?

In my 4W practice amp, I wired a single Ge diode (switchable) across the signal path after the first stage - may be too subtle if you're into super heavy distortion. I leave it on most of the time & control the distortion with guitar volume.

For a heavier sound, try a pair of silicon diodes back-to-back in the same spot, or even more extreme a pair of mosfets. The key is finding the place in the signal chain that has the necessary level for the particular diodes used.

Unfortunately, I do not have much experience with diodes etc... I pretty much need to find someone to do it for me unless it is very easy as JMFahey says.

Easy is all relative. Driving a car is easy unless you do not know how to do it. All the easy things people have done usually comes about from somebody putting in some effort in.

You are 100% correct.

This one is the deluxe version: adds a full distortion stage, with distortion/gain and volume controls:

This is the absolute simplest, but sounds quite good: adds extra gain and clipping diodes with just a simple switch:

You're the best. Thanks a lot
