Just wanted to let all of you know I saw a used Ampeg V4 at Guitar Center in Arlington Heights, IL. The price tag said $499. Not bad at all, and of course I tired it out! A few power tubes were missing, does not distort at all like a normal guitar amp - no Marshall style distortion or anything like that (I tested it with a $3000 Modulus 5 string). Basically was really clean sounding. Did not look like much work was done to it, decent condition, looked REALLY OLD. Not sure of the year. A few of the tubes looked old, but I did not spend enough time checking that out. Just wanted to let all of you know of the great deal at this Guitar Center.
