Well I just went way over my budget and got the DB750. I originally went in to play through the iAMP-800. But Gary already had the DB750 hooked up to the GS412. I have GASSED for the DB750 for awhile and thought how nice it would be to hear my bass through it. Plugged in powerd up and hit the low B the thing had me at HELLO! Anyway I really liked the GS412 with the DB750 but as I stated I am already over my budget by a grand. So I opted to wait before deciding on another cab. Currently I am using a pair of Acme B2 series II 8ohm cabs as you guys know not the most efficient cabs on the market. I had been pushing them with a GK 2000RB bridged. Searching the threads I have found no one using such a configuration. Tombowlus did his 2x10 shootout using a line driver and a Crest CA9 here is his comment "Acme Low B-2II – Very deep and very full sounding. Also a very clear cab, but with less mids than some of the other cabs, and brighter highs than Cab A. I’d say that it is slightly mid scooped, though not perhaps compared to other cabs not in this shootout. This cab was louder than I expected, but it couldn’t take all that the CA9 could put out without showing signs of stress." I haven't had the opportunity to play through the Acme's yet probably at rehearsal on Tuesday (to busy to go pick them up) I am very fond of the GS412 however I am concerned about the weight. Has anyone gigged with a pair of B-2's or even tried them with the DB750?
