Here's my story. In my new band theres two guitar players tuned real low, Db to Db and drop to B for a lot of songs. Both guitars play thru Marshall rigs, one 4x12 and one 4x12+2x12, so they are extremely loud and sound good. But I'm getting buried in that mix, even tho we are in the garage right now and playing in clubs we wouldnt be quite that loud. We'll be playing all different size clubs/bars. My rig kept up with my old band, but now I need to be LOUD and have huge bigass low-end. I have a Eden time traveler 330 watts, and a peavey tfx 410, and I've been turning it almost all the way up and pushing it way too hard. I'm thinking I'll need to add a 18 cab to what I've got, and maybe get a power amp if I need to and use the eden as a pre-amp (since I just bought it not too long ago and I like the sound). Would this be my best route to take, or is there a better way to get the big lows I need? What are some good subwoofers for bass rigs?
