I'm hoping NO, b/c I have a very specific setup in mind for one of my various projects, and right now I use a A/B switch to accomplish my goal.
I send my Taylor T5 through an A/B switch, one side goes clean to the L1 (preset 98) and the other goes to a Fender Blue Junior which is miked with an SM57 and run to the L1 (preset 27). I've found I love the combination on the two, it has an incredibly full sound. Sometime I use just the miced amp, especially if I start using FX, but never the clean channel by itself. Although the T5 sounds great clean, if I wanted a clean acoustic tone, I'd use my 414.
If the direct outs don't mute, I can ditch the a/b switch and run the T5 to channel 2 on the T1, use the direct out to the Blues Junior, mic the amp and send it channel 3. When I want just the amp tone, I could just mute channel 2. The drawback is that I couldn't get just the clean tone b/c I'd always be sending to the Blue Junior, but as I said, I don't ever do this.
