Always happy to help, Nick.
Re your first and second points about placing the ML in my amp FX loop: my amp is a 30w tube stack (monoprice stage right) that has an adjustable gain switch for the FX loop, with options for either 0db or -10db. In your opinion, would the -10db setting be enough to tame the signal from the amp head preamp?
This is definitely one of those cases where I would really like to find answers with hands-on experimentation. The ML has a pad switch on the instrument input, too, but the input is designed for a high-impedance signal, not line level. The combo input on the back of the ML is better suited for line level signal like from an amp. That said, MAYBE padding your amp with the -10 dB switch and connecting it to the instrument input might work. The main concern is obtaining the proper gain structure so that there is no disparity between bypassed signals and with the ML signal chain engaged, and balance between mic and guitar. The other variable is maybe this can also be assisted by any level controls present on downstream or in-the-ML-loop effects. Again, it’s a worthy experiment.
I know I would likely still have to fiddle with the input gain on the ML when switching between guitar and vocals, but I plan to use a looper to layer parts while practicing and could adjust the gain between takes. I’m more curious if this is the “level of control” you’re referring to as something that most amps lack.
The pad switch on your FX loop is more than most amps offer, but as a self-proclaimed tone ninja, I would want more control.
