(First of all, I already apologize for my english I am going to buy a combo amp to use in rehearsal and little gigs (club, cafés ...). Of course, i haven't got much money, and I'm wondering what's the minimum power I need. I play rock in a trio (drums, guitar, bass), which plays not loud as metal but sometimes ... hum ... powerfully (?). So 150W ? 200W ? 250W ? 300W ? What do i need ? I tried Warwick Sweet 15, Warwick CCL, SWR Workingman's 15 and plan to try some Hugues & Kettner (XL 200 and XXL 300) and some Ampegs'. Other question : what's best : 1x15" ou 2x10" ? PS : i play with fingers and slap (25%), on a 5 strings (BEADG) Bass Collection (SB465) with Bartolini pickups.
