I've been drooling after a 408 (or the new Monolith reproduction) for a while now, especially once I heard that Matt Freeman from Rancid used one for a long time (big influence), but I feel like that would be bordering on
too much...at least for now. I personally think that I would love it, but sound guys on the other hand....thats a different story

. Plus when we are on the road, we will go from a nice music hall (where the 408 would do nicely) to a small DIY venue (where it would be
too much) and everything in between. That is why I have put the 408 on the back burner for the time being and decided to shoot for a 2x15 as it may be best for more types of shows in the immediate future.
While I totally dig that super smooth round "old school" type of bass sound, I'm more into that more modern grindy type of sound. I need a lot of clarity (i.e. opposite of mud) and I like a fair bit of grit to my signal too, though I like to be able to tame that with my hands. I'd say my current set up (I play a BTB676) is like 96% there. The only real gripes I have with my sound are minor ones.
I feel like the signal from my bass is too hot for the input on the 370, and even though I play through the 2nd channel, it is still too overdriven sounding when we play. We play loud. Very loud, and sometimes I feel like I have to push the amp just past the "sweet spot" to get it where I want. If I back the volume on the bass a bit, it cleans up nicely (one of the things that I love about the 370), but I don't have the time/finesse to mess with my volume knob live.
P.S. I love being way underneath the guitars in my band, and that low, full, lush rumble that comes from a big cabinet is something that I've always loved. I want it to really rumble everyone when I'm playing.
P.P.S I'm playing with different ways to make the input thing work either by using a boost pedal (the Wren & Cuff Phat Phuk B) to cut the signal and just leave it on until I actually need a boost, or get a compressor or new PUPs or something...I'm not sure yet.
