Fender Concert amps were produced between 1959-64, with this one from very late 1961. Very early wheat grill model.
 
It is equipped with 4 x 10 inch speakers and delivers a smooth sound at low volume which can become a blues beast if you push it to its limits.
 
The Brownface Concert has a unique harmonic tremolo circuit that sounds absolutely fantastic. Same tremolo as the one you find on Super and Bandmaster (combo version). Comes with orginal footswitch.
 
It is a late 1961 & US version with 110v (comes with a new external transformer). Original footswitch included (with replaced switch).
 
Just serviced and ready to gig
