Hey guys. Getting a bunch of new equipment in the near future since I'm now at a point where I can say that playing bass is a side-line job rather than a hobby and I feel that my current gear isn't good enough right now. I'm planning on using this for as long as possible in a variety of venues and bands but primarily, in my 'rocky' wedding band, with 1 guitar, keys, drums, bass and 4 vocals. A luthier friend of mine is currently putting together a new workhorse 4-string for me (http://i665.photobucket.com/albums/vv12/kanped/20130201_113729_zps834e75f0.jpg). It's going to have Seymour Duncan SBP-3 quarter pound pickups in it when finished. I'm also using a stock Ibanez BXP-5 but I really want to put passive EMGs in it and throw the damn active EQ out of a window at some stage (I'm a 'set everything on the bass to full, let the outboard get the sound' kinda guy). For now, all that's still there and being used. I've never really gone this in-depth with hardware before but I've done some research and this is what I've come up with; First thing I definitely want is the upcoming SansAMP VT Bass Rackmount pre-amp. I've been using the old DI for many years and I've always loved it but I think it's time for an upgrade now. Tone comes from here, because the tone is awesome. Power amp; I was looking at the Peavey IPR 1600 DSP. I want this rig to be as portable as possible; we play a lot in venues with thin, tall, wet outdoor staircases and heavy stuff is always a pain. these seem solid to me, the price is decent but that's all I know. I think I will make use of the DSP elements for the crossover if nothing else. I'm not 100% sure if the power is enough considering what I'm planning with the cabs. So, my luthier friend and I are planning on building the cabs. This is the bit I really need advice on because I've done a lot of research and I think I've got a good proposition here but I may be making a huge mistake, I don't really know. The setup is a 15/6 ( 18 Sound 15MB606 / 6NM410) and a 15 sub (FaitalPRO 15PR400). I really like a lot of percussive mids punch in my tone but I can get that through my current 15" with a tweeter in spades (SansAMP into Carlsboro Bass Beasty). When I use a 5-string, though, I don't get the big, big lows I want. This seemed like a good way to do both, and also allows me to ditch the sub if I'm playing smaller venues. Dunno if that's enough to go on for advice, but I can't think of anything else to say about it... so... thanks in advance, guys.
