The core BP1 tone at half the size 

BP1 Compact crams the essence of our beloved BP1 Bass Preamp into a compact stompbox format and you get the core tone and extremely low noise level at almost half the size – and price!

BP1 Compact and the original BP1 Bass Preamp sound very similar, yet each has a sonic flavour of its own. Which one you prefer comes down to taste and preference. We like to think if them as to distinct flavours of sonic greatness – and there is definitely a place for both. 

BP1 Compact adds that critical definition in the low-mid part of the sound, making your bass sit in the mix with ultimate definition and tons of dynamics.

With the transformer-balanced, studio-quality DI, you will no longer have to use low-quality DI’s at venues that make your bass sound dull, two-dimensional and uninspiring. The FOH engineer will love your bass signal, and the crowd may not know why, but they’ll love the huge – yet firm and defined – low end that is the foundation the overall experience builds upon.

But perhaps most important of all, you will have the bass tone of your dreams on the stage, ensuring that you can focus entirely on those solid grooves, tasty bass lines and simply making everyone else sound their best. 

This is a no-brainer pedal with Gain and Level controls. Simply plug your bass into BP1, trim the Gain and Level to fit your taste, and experience the mind-blowing tone this unit has to offer. In fact, we bet that once you have set it, you will just leave it on at all times, as it will simply enhance your core tone at the most fundamental level.

We also added Tuner Out and a patch-point (send/return) in case you use additional stompboxes or other external equipment. The patch-point is placed after the input buffer – but before the preamp section.

To make your gigging life even easier, we designed BP1 Compact to run on 12VDC – perfect for your pedalboard.

What do you get when you add a BP1 Compact Bass Preamp to you signal? In this video, bass maestro Janek Gwizdala demonstrates exactly what happens when you stomp the BP1 Compact in and out of your bass signal chain.

NOTE! As always with critical listening, please do not rely on the built-in speakers on your mobile device, but use headphones or good speakers!
