I've been using my FM3 in a 4CM setup with a Mesa Boogie Mark IV at -10db for a while and it's been working out fine although I have to put my amp output volume at like noonish. I recently picked up another amp that doesn't quite get a good amount of volume at -10db without maxing the output volume on the amp, which seems like it might be stressing the power tubes pretty significantly. I attempted switching to +4db on the output and it worked out much better but I'm curious if this is safe on a normal guitar tube amp.
The wiki said "Set to -10dB when connecting the input to a pedal, a guitar amplifier input or when the output is clipping the input section of another device. Use +4dB when connecting to the output of a pro level device or to a louder output signal." This made me think that +4db is not safe for a guitar amp potentially, because "pro level device" seems like it's implying a mixing board or FOH. I'm not triggering any output clipping lights on the FM3 and everything sounds fine but wanted to check if anyone knew for sure if this is ok to do or not.
