A Message from the Chairman

Since 1946, Fender realized the importance of your amplifier. You see, your
amplifier is more than just a combination of dials, wires and speakers. It is a
finely tuned musical instrument. And like any fine musical instrument, it
should be treated with special care and attention to detail.

At Fender, we know what building guitar amplifiers is all about. For over half a
century, we have been designing and producing some of the world’s best
amplifiers, helping shape the face of music. In fact, many of the world’s most
classic and best sounding amplifiers proudly wear the Fender name.

Whether you are after that classic Fender tone, a clean crisp sound for your
Bass or Keyboard or the raw driving power of modern distortion, your
decision to purchase a Fender amplifier is one you will appreciate with each
passing note for years to come.

Wishing you years of enjoyment and a heartfelt thank you,

Bill Schultz

YOUR ACOUSTASONIC SFX AMPLIFIER

Congratulations on your purchase of a Fender

detail, your Acoustasonic SFX offers much more than

digital signal processing, a dual channel power
amplifier and both phone and XLR input connections.
The two independent channels with their individual
tone controls are voiced for acoustic instruments and
feature a feedback notch filter control which
attenuates ringing and other bothersome hums.
Moreover, the exclusive “String Dynamics” control
(patent pending) helps suppress unwanted high
frequency harshness. Still, the front panel features
insert patch points for the addition of external signal
processing devices or other outboard gear.

Acoustasonic SFX

Fig. B Fender’s Stereo Field eXpansion circuitry (patent

pending) processes the signal through one of 32 available
stereo digital effects. The stereo signal is then processed
by the exclusive SFX matrix circuit and sent to the speakers
creating a psychoacoustic event that results in up to 300º
of stereo imaging.
