Dont do it. I had one that worked, and after getting a new amp after I realized I didnt like the Tantrum....i would never get one again. Sound quality sucks!!!
he wasn't asking for opinions on the amp, he wanted to buy one. anyways since you opened this can of worms the tantrum is an excellent amp, that is underrated and versatile. i want one myself actually, and i have owned a tantrum before.
Check the PG direct store on ebay. I saw a 1200 for $325 last week. With manufactures waranty. If there isnt one listed contact the ebay store and maybe they will list one for you.
netherland has a Tantrum 1200.1 for sale in his For Sale thread that just got posted. Dunno how much he wants for it or anything....but there's one in the classifieds here up for grabs!
