When I saw Larry Grenadier play with Mehldau at the Vanguard a few years back, he was using one of those JBL powered (I think) PA speakers to amplify his bass on stage. From out in the audience it sounded fantastic. He had the speaker up on a stand near his ears, presumably to hear himself better. Anybody else use/try a similar configuration? I've been thinking I might pick up one of these (New Mackie DLM12) and give it a try with my little Headway preamp. Thoughts? FWIW, my current rig is my Mesa Walkabout Scout combo with my headway preamp upfront (basically just my EB rig plus the preamp). Sounds alright, but I'm wondering if I can do better.
