The Farfisa amp page.
Here is a Farfisa amp dating from around the 70's. I don't know if it's a keyboard or bass amp...
Sure enough, it's cool for guitar as it delivers a super-clean sound with a "cave" reverb: nice!
Detail on the front pannel. Two channels, with high/low entries. This amp must be a 100-watter, as it has four EL34.
Overall, a very clean amp, in perfect order!
