im just trying to make sure im not damaging my Marshall Head by doing this.
basically my current experimental setup is:
PODxtLive into FX loop return to bypass preamp, so i can use the PODxtLIve for clean settings.
the input on the POD is routed into an A/B Switch using A, and the B is routed into my Heads input. this way i can switch from bypassed preamp, to Using the preamp so i can kick in my Marshalls Crunch channel.

what im wondering before i ruin my amp, can switching back and forth from bypassed preamp, to using the preamp hurt anything?

just want to make sure before i start using this idea for band practices etc.
