90w, 2 speaker outputs in jack, 1 headphone, 1 line out
3 channels with 2 inputs jack, 1 serious, 1 acute, 1 switch effects loop, reverb switch 1 on each
1 effects loop
1 spring reverb (excellent) with its volume and an input for a pedal switch
1 and setting attack
1 master volume
A very clear sound.
I use it for 25 years without any trouble ...
I did not like the piezo of the original speaker, but I only kept the amp head and uses connected to two returns. Perfect for keyboards, vocals, acoustic guitars.
This amp was a bit expensive at the time (1989), but finally given the services he has rendered me and reliability, I do not regret my choice!
