In my local newspaper, I was searching the classifieds. I found a "Vintage" 1969 Ampeg Colossus . 300 watts, 4-12" Altec Lansing speakers. Head and Cab. $500 The guy claims it is in "Mint Condition". Is this a good deal? Do you know what these sound like? Is this a bass amp? ( i am sure it is ) Any input would be helpful! PS Also, the guy selling it only lives about 15 mins away, so i might be able to try it out!
