If a 350-watt combo isn't getting it done in rehearsal, either there's something seriously wrong with the amp, your settings, or most likely, your band is just practicing way too loud.
I run a 150-watt Line6 LowDown in full band rehearsals with acoustic drums, electric guitars, keys and vox, never turn Master Volume past 5 and everyone hears me just fine.
