Richter 3BP 3-band Preamp

The 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 custom instruments.

The onboard circuit in combination with the battery power supervisory is a patent pending product. When the blue LED starts to flash the battery is getting low and needs to be changed within roughly 10 hours.

All BassXX EQ's/Pre-amps are completely shielded, this means no additional shielding of your instrument control cavity is required.

Features

Please Note:

Installation of the preamp will require some basic soldering skills. Instead of not being difficult, professional installation is recommended.

Note: Excessive heat and incorrect soldering equipment usage or selection may damage the electronics.
