So I think I have a new one for you.
I have an Acoustic 450 head running through 2 custom cabs.
A link to a 450 description: http://acoustic.homeunix.net/twiki/bin/view/Acoustic/GuitarHeadOrBassHead450
One is a Roland C-1238b open back with an Xtant 12" car sub closed, ear firing (yeah I'm a bit odd)
The upper cab has 2 Alphine W-1200 (knockoff 12" labeled as 240W 4 ohm) and a Jenson JCH 10/35 8ohm. Open backed.
Overall I like the sound I'm getting, the 10" distorts wonderfully, though I'm amazed I haven't killed it yet.
My problem is that one of the Alphines is literally falling apart (being held together with c clamps).
I play a variety of metal, grunge and alternative with both a BC Rich virgin with Zakk Wylde 60's and aBD-2 pushing an HM-2 for distortion. My other guitar is a Fender Strat Squire using a Metal Muff.
I guess my question is what should I replace the dying 12" with? I'm pretty sure I have the low end covered so I'll need some good strong mids and decent highs.
