I have a need for a small stompbox-sized volume pedal for use at our practice space. I'll only be using it for level setting, not for swells. I've seen conflicting reports here and elsewhere about the AMT LLM-2 - some people complain about the taper, some say it's a bass tone suck and still others say it's fine. Can any current users chime in? For reference I play all fivers, both passive (P5s) and active (EBMM, Fender Dimension, Synapse.) Thanks!
