upgrade for the 
Fender Princeton amps

RECENTLY UPGRADED WITH SUPER HIGH PRECISION DALE BRAND RESISTORS - WAY COOL!

For any of the Princetons or Princeton reverb amps covered in Black tolex (1964 - 1980)

An easy kit to "blueprint" the Fender Princeton amps. The kit gives more power and a bigger, full tone from those great old Princetons.

The kit corrects design errors in the amp and gives it a stronger, cleaner tone with a bit more power and sweeter overdrive tone. An EZ kit to install
