I wouldn't get a mode 4 cab cause those are made for one purpose, to go with the mode 4 head... Not to mention they are wayyyyyy expensive... they are like 800-900 bucks.
Also another theory of mine, but please...by all means feel free to flame me if I am wrong... But a bass cabinet for a guitar is just....it's just wrong man.... The guitar is a full range instrument, and if was meant to play bass, then it would be a BASS guitar... The only guitar that MAY even benefit from that kind of situation would be a baritone.

Check out a Carvin cabinet, hell even their Legacy cabs are like in the 500 dollar range... but their normal cabs have a great tone and are inexpensive.
