Mozztronics BP-2 Bass Preamp
Inspired by the “Classic” Valve Bass Amps of yesteryear, we replicated the valve circuit in solid state with op-amps. We tweaked and optimised the tone stack so you can get a wide range of sounds. We kept the inductor based mids control, which has five switchable frequency bands, to get as close as possible to the sound of the amplifiers you know and love. This unit is 100% analogue in the signal path. No digital simulations here.
There are two main uses for the Mozztronics Bass Preamp BP-2. The first is on a pedal board to add in a preset eq, or leave it on all the time to add extra tone capacity to your existing amplifier. The second is for home recording so you can get a great bass sound without micing up an amp.
Controls are exactly what you will expect to find. The main preamp controls are GAIN, BASS, MID, MID (frequency) switchable between five different frequencies, TREBLE, and VOLUME. We also have kept the ULTRA LOW and ULTRA HIGH tone contour switches. For best results start with VOLUME fully clockwise and adjust GAIN up to the desired level.
While the BP-2 bass preamp can get dirty with the GAIN cranked, for best results set the VOLUME to maximum, and the GAIN lower, and use a Mozztronics BOD-1 bass overdrive in front of this pedal to add in the dirt. The combination of the BOD-1 bass overdrive and the BP-2 bass preamp gets an excellent replication of a cranked “classic” valve bass amp.
If you are recording, as with any recorded track, you may need to apply some equalisation or other effects to the signal. Play around also if you have a VST cabinet simulator with your recording software. Try with your software VST and your favourite speaker response. There is no right or wrong, if it sounds good, then it is good.
