I've been playing through a 100W Crate 1x15 combo for a few years, and I am looking to upgrade. (The Crate is OK, but just not enough power or sonic clarity for what I am needing these days.) I'm looking for either a higher-end combo or a cabinet system that will work in two somewhat different situations: 1. A church worship band where I am onstage with piano, 1-2 guitars, drums, and 5-6 vocalists and running through a fairly massive house PA; and 2. Gigs with a 3-piece rock/funk/blues band that plays coffeehouses, church gatherings, parties, outdoor festivals, etc. I've been reading the thread on church band setups elsewhere on the forums, and most people there are happy with a 300-400W head and a 4x10 or even just a 2x10. But I wonder if that would be enough for the gigs with my 3-piece band. A 300-500W head with a 4x10 and a 1x15 would be great, but obviously a greater expense than just the head + 4x10's. Any thoughts on what kind of setup would serve both purposes well?
