I am debating on whether to get a 2x12 cab of some sort and run my acoustic throw my marshal jcm900 or get a combo amp? If so are there any decent combos in the same price range as a 2x12 with celestion v30s.
ESP LTD EC-1000 vintage black
sunburst fender MIM tele
Epiphone LP standard ebony
Mesa/boogie dual rectifier
Mesa/Boogie .50 caliber plus head
Marshall JCM900 Hi-gain MII 2500
Fender Hot rod Deluxe
Acoustic amps use less gain, which results in less of a chance of feedback. My Rivera Sedona will still feedback with my acoustics, but nothing like my Peavey or Mesa amps.

Best to use an acoustic amp with an acoustic guitar.
