I'm considering calling LDS up and having them build me a cab. Let me say, I play both electric and upright. Jazz, slap, funk.. The two situations I play in are a quartet and big band. I dont need anything rediculously loud (I have PreGibson Trace Elliot (2) 2x10s & (2) 1x15s for that)..Right now for jazz gigs I'm using a SWR Workingmans 10 but I think its days are numbered playing double bass through it. I've had a slew of problems with it. I would like a good, decently lightweight cabinet that will handle the lows of the double bass well and be punchy for slap. I was considering getting a cabinet made with a 12, 8, and a horn.. Does this sound like it would work well for me?? For head, I'm going to be running a GK700RB. I'm going to ask if LDS can use speak-on's on their cabs so I can fully utilize the head (one channel for the 12 & 8 and one channel for the horn). I'm not set on a 12, 8, and horn so if anyone else has more suggestions, I would greatly appreciate it.
