November 2, 1984 I bought a brown Fender Super Amp serial # 00143 for 175.00 at Voight Music Center in Beloit Wis. The odd thing about this amp is that it had ONE 15" Utah speaker and not the 2x10" combination that you usually see. Could this have been factory? I have never seen anything like it since then. Thank you for your help.
Man, it's only my "educated" GUESS ... but I'm going to go with modded.
Super cool amp, by the way!
