Hello, Let me start off by saying that just a good cab is in question, I know that a new head would help but circumstances prevent it. Okay so I play with my school's jazz band (I'm kind of the electronic-savvy guy or something) and recently the cabinets we have been using for the bass amp (some GK 210 and 115) have been slipping in and out of being blown (the other bassist, without my knowledge, has been poking the speakers with a pencil through the grill after they sound blown and it fixes it temporarily). So I recently brought this up with the band director who asked if I would look into some cabinets to replace the ones we have (she is more of a brass player, so she doesn't know about bass stuff too much). She said around $800 for both (or one good one I assume) but it can be a little more if its a really good one. So we're playing through a GK Backline 600 which is pretty good in of itself and the band director wants a nice warm 'fat' tone (kinda like JPJ on Dazed and Confused). We're using a MIA Jazz Bass and an Upright with a Pickup on it if it matters. My question is, what cabinet would be best? At first glance these popped out to me: http://www.musiciansfriend.com/amplifiers-effects/ampeg-svt-410he-bass-enclosure http://www.musiciansfriend.com/ampl...ass-speaker-cabinet-with-horn/h70810000001001 http://www.musiciansfriend.com/amplifiers-effects/aguilar-gs-410-bass-cabinet She did ask for like 4 or so choices so, any input would help, Thanks!
