BassXX Preamp (pronounced "Bass-ics") is a filter-based pre-amp which
provides very flexible parametric EQ control with sweepable mids. Its outstanding
sound performance is achieved through careful circuit design with attention to
detail and selection of finest components available.
It has an extremely low
noise floor and a tube-like dynamic response. The warm and smooth sound has no
discernable hiss even at extreme high frequency boosting.
Because the input
impedance is higher than most other bass and guitar preamps, passive pickups will
retain their natural frequency response and tonal character, as well as piezo
ceramic transducers will do.
Pulling 'up' on the treble control achieves true
bypass of the EQ and allows for passive operation.
The passive sound is virtually
identical to the active sound in tone and level if the EQ is set flat. In passive
mode, only the volume controls works, but passive tone control can be added on

and needs to be changed within roughly 10 hours.
BassXX EQ's/Pre-amps are completely shielded, this means no additional shielding
of your instrument control cavity is required.
definition amplifier design results in precise and smooth sound reproduction without
precision metal film resistors in the signal path with a resultant noise factor
of up to 10 times lower than standard thick film resistors.
