I am very curious about the Phil Jones Briefcase. I play worship music once a week in a coffee shop setting with a acoustic guitar and 3 singers. We use a real monitor rig for the VOX with some acoustic guitar in it. The monitors sound like well Peavey monitors so I am not excited about putting my bass through them. I'd guess stage volume is probably 93-96 db depending on the day. Today I use a Markbass LMII and a Traveler 102P which is more than enough. My question is would a Phil Jones Briefcase get the job done with some headroom left to spare? Also how well does it handle a Low B string? I have always liked the idea of that amp and thought I'd like to have one if the opportunity presented itself. Comments would be appreciated.
