Re: Controlling Two Blackstars - One Foot switch

You could just use a footswitch with a TRS type output, then split that output with a “TRS to 2 TR” adapter, one going to each amp.

Re: Dead clean channel

A power valve would impact both channels.

Changing power tubes often requires rebiasing the amp. I’m not sure about this model though.
