I had a Marshall 100 Bass Amp (into a Peavey 610 cabinet) in the late 70's...it was an awesome amp. The gear snobs in my band, at the time, said I needed a SVT or a Fender Bassman and a Fender Pbass. I soon left that band and played my Aria 1420 Beatle Bass through it for the next 4 years! Simply a very nice amp from what I remember.
