Our church got a new PA with XLR mic inputs up front and a mixer with phantom power in the rear. I have a Peavy Max Bass preamp with a DI out, so I'm covered. For the guitard players, they are all acoustic, some with built in pickups. One guy has passives, another has one of those new acoustics that has built in pickups with a built in preamp as well. $200 active DI's are out of the question. Anything in the $50 range running off phantom power?
