“1/2 Blackface” Mod

Please select amp model

This is a great mod for those dreaded “ultralinear” Fender amps of the late 70’s.  All 135W & 70W silverface Fender amps are “ultralinear”, and quite different from their blackface & earlier silverface relatives.  They are known for sounding “colder” and “harder”.  Different transformers & power supplies make these amps impossible to truly “blackface”, but it is possible to get them to sound better and have a much softer feel!

These kits are easy to install and improve the tone, feel & touch sensitivity of the ultralinear Fender amps, bringing them several steps closer to the feel and sound of the beloved blackface circuit. Signal cap upgrades also help to make these ultralinear Fenders much sweeter.
