I'm looking for suggestions for 15" combos that bypass the Preamp via an effects loop. I could do a separate power amp and cab, but thought there might be some decent stuff for cheap (used is great) that has that. I don't need a ton of power, 100w plus is fine. Just need the Effects loop to accept line level. Also need the cab ported somehow, i don't like sealed 15's. Suggestions? Thanks i'd be using a preamp in on the loop. Again i could do separate power/cab but that might cost me more and this is just a small rig for corporate jazz real book gigs, don't need a ton of power, just need light and compact.
