I owned a Fender Super 60 and did over 250 shows with it. Other than replacing a jack socket and some valves it was very reliable.
The Super 60 was not desgned by Paul Rivera, who had left the company by then. Although I am not so keen on the sound of the Paul Rivera era amps are probably the best made Fender amps. They are the last of the eyelet board hand-wired Fenders,and I think do to the quality control problems Fender experienced in the late 70s they really pulled their finger out when Paul Rivera came in to design the amps. The Rivera era Fenders are now becoming quite collectable.
The Super 60 is a PCB built. The earlier ones had Red knobs, this is often their defining feature (ie its a "red knob era" Fender). These are cosmetically regarded as an undesiable era of Fender amps and as such I often see Super 60's for around the £200-300 mark. I certainly wouldn't pay more than £300 for one. That's a lot of amp for the money. Whther these amps will become collectable is anyones guess (although I still find it amazes me that late 70s Strats and Teles are collectors items). Nevertheless as ong as you don't pay over the odds you certainly won't lose money on a Super 60.
Regarding the sound. The clean channel went back to the older "Blackface" style pre-amp (the classic Fender pre-amp for clean sounds) which had been abandoned in the Rivera amps. I like this and used this channel almost exclusively. The drive channel is a bit fizzy (back to the 80's!). I only used this with a humbucker loaded guitar, or at quiet gigs. The reverb is fine, but not as nice as the old valve driven circuit.
I did do a gig running the amp through a 4 x 12 and it sounded very good. Bear in mind though that the Super 60 doen't have an impedance selector so you may have impedance matching issues when using an external cabinet. I am not convionced by the internal speaker, although that could be a general dislike for 1 x 12 50 W combos.
If you wanted to spend a bit more more and didn't want channel switch or distortion channel, then you might be better off looking for a Silverface Pro Reverb. This is a 35-40 2 x 12 combo that seems under priced at the moment (you can still pick them up for under £500). These are starting to become collectable and will appreciate in valve.
Conclusions, if you are after the classic Fenedr clean sound, this is a relatively cheap amp to achieve that. You might even like the OD channel.
