I'm tempted to get one of these little amps for rehearsals (and possibly a back-up), and I've read the specs that say you'll only get the full 20w at 4 ohms....so assume it'll be quiter with higher impedance cabs...is that right?

Now I've got a 16 ohm 1x12 with a Vintage 30 speaker (which I tend to use at rehearsals) and two 8 ohm 2x12s (which I use at gigs)

Has anyone tried the MT through a 16 ohm 1x12, and do you think it's actually be loud enough for rehearsals? (that's with a drummer and bass player, just me on guitar).

I've watched a few youtube clips and everyone says they're loud, but it's difficult to guage that from the vibs.

Thanks.
