I see, I usually put effects on my effects loop, you're just saying put it in front of the chain. PLUS I could use it for my Streamliner
Cool
+1 With the true bypass, you won't even know it is there, and will serve as a nice tuning mute. I believe the Pitchblack tuner is also true bypass, and while it doesn't have the accuracy are quite the tracking speed of the Sonic, it is half the price. Also a good option.
However, for you specific, unusual situation described above, I would just turn that head around on the cab so it is facing you... issue solved I think!
