plifiers, it became obvious that there is a large market for a bass amplifier line that reproduces the natu-
ral tone of the instrument itself, while allowing for personalization of tonal texture.
As with our speakers, Genz Benz amplifiers strive to maximize your instrument's natural tone and feeling
without imparting additional coloration or reducing impact and playability. This results will always be true
to your instrument's basic natural qualities and your personal tonal signature.
The circuit design, features and physical construction have been carefully calculated to give you, the ex-
perienced player, the best performance and value in bass guitar amplification. Featuring sturdy jacks and
controls, 12AX7 TUBE and solid state FET front end pre-amps, foot switchable channels and shaping
filters, 5 band active eq, a balanced direct output and an industrial duty bipolar power amplifier with tor-
oidal power transformer, the Genz Benz GBE-600 bass amplifier gives you the tools and versatility nec-
essary to sound your very best on stage.

This is one important reason Genz Benz amplifiers sound so big. - Page 3 4 button footswitch. Input Gain Controls & O/L LEDs — The “input gain” controls, in conjunction with the signal and clip LEDs, allow you to adjust the preamp input gain sensitivities to the instrument you are playing. Basses can have an output level from a few thousandths of a volt to several volts.
- Page 4 Effects Insert Jacks — The “effects insert jacks” are provided to allow access to the pre-equalization signal for the purpose of inserting signal processing equipment such as compressors, chorus, delay & reverb processors. “Send” (output) and “return” (input) are nominal +4 dB level. “Series” devices (such as compressors and gates) require that the signal flow out from the send jack on the amplifier, through the processing device and back into the return jack on the amplifier.
