It's an interesting coincidence, my Reverberockets were also high school buys. Got 'em at Massimino on the East Side. My father was friends with the owner (not sure of the connection), and he gave us a deal. One was originally my brother's, but he eventually lost interest and got into the visual arts; so I had one for organ, one for guitar. And there were times I daisy chained them and used both together.
The Ampeg amps were good for certain things - very loud and clean for their size and power - but definitely an acquired taste. As soon as I started making gig money, I lusted after, and finally got, a Black Panel Bassman head and 4x12.
The interesting thing was that the lower powered Reverberocket was actually more solid, and with more undistorted low end with the organ, than the Bassman. But for guitar...yeah, the Bassman was great.
HiWatts did a thing...I never found them too bright, but also never owned one. Have had them in the studio to record, and liked what I heard, but everything is always about what they're hooked up to on both ends - guitar, effects, and of course speaker cab.
