Ground Lift - Fender Downtown Express Manual

Drive (Overdrive)
The Drive control adjusts the saturation added to your instrument's
signal. The overdrive is voiced with Speaker Simulation to create warm,
amp-like drive even when using the XLR Output directly into a console
or playing through a speaker cabinet with a horn.
Blend (Compressor)
The Blend control changes what the player hears when the compressor
section is active. In fully counter-clockwise position, it provides the
original unaffected signal. In fully clockwise position, it provides the
output of the compressor section only.
Gain & Gain Reduction LED (Compressor)
The Gain control affects how much of your bass' signal is fed into the
compressor circuit. The Gain Reduction LED indicator will change when
gain reduction or compression is occurring.
Threshold (Compressor)
The Threshold control adjusts when the compressor starts to affect the
signal.

electric guitars, acoustic guitars with pickup systems, keyboards and
other instruments.

interrupting your signal path.
