I've been having some back trouble lately, and that coincided with a new gig backing a youth Gospel choir- rehearsals and concerts all over the place, often at a distance and a few flights of stairs away from the parking lot.
So, I bought a Fender Rumble 100, modded the cab to tighten up the low mids, and have been using that with my electric slab. Gives me a nice, thick Ampeg-y sound that suits the fast walking bass parts in a lot of Gospel shouts. Surprisingly, the open low B punches through a lot better than I would expect from a small, 100 Watt combo.
It sounds great in that context, so I thought I'd try it for an acoustic set with the Guild.
Big mistake. The EQ that makes that amp work on electric, triggered resonances at relatively low levels, making some notes ring on unnaturally, as though they were right on the edge of feedback. It didn't matter how I adjusted the 4-band EQ on the Rumble, I couldn't dial that out.
I went back to my AudioKinesis 112 this weekend, which is pretty much an FRFR speaker, and bingo- the Guild sounded amazing again.
I'm wondering what everyone else uses for amplification with their GSAB's?
