AC Inlet Replacement
Fender Super Champ

Fender® Super Champ® guitar amps, launched in 2007, marry a digital preamp to a classically warm, Fender Princeton, vacuum-tube power amp.

The digital preamp, shown below, is made up of:

Preamp
  1. A Texas Instruments, digital signal processor (DSP)
  2. A software operating system
  3. Random-access memory
  4. A connector for input, output, and power


Control panel

The preamp has two channels.  Channel 1, the clean channel, has only a Volume control while Channel 2 has both a Gain control and a Master Volume.  The Treble, Bass, and F/X apply to both channels.

Channel 2 also includes a 16-position Voice control that models the sound character of various legendary guitar amps.

 

 



Inside the chassis

Inside the chassis of the Super Champ you'll find:

  1. A digital preamp
  2. A vintage, Fender® Princeton, dual-6V6, vacuum-tube power amp
  3. A power supply
  4. The user controls and their data lines.

 



The only thing this amp needed was an AC inlet jack to replace one that was broken.

This unit is a Super Champ XD but the X2 uses the same AC jack.

The X2 has a USB interface for tinkering with DSP settings and recording to a DAW.
