Studio-quality bass preamp at your feet

The preamp from our BAS1 Bass System – on the floor! 

BP1 crams the preamp and output stage from our BAS1 Bass Preamp System into a compact stompbox format with zero sonic compromises.

 The BP1 adds definition in the Low mid-section to your bass sound. It will make your sound sit in the mix with the right definition and tons of dynamics.

With the built-in transformer balanced, studio-quality DI, you will no longer have to use low-quality DI’s at venues that make your bass sound dull, 2 dimensional, and uninspiring.

This is a no-brainer pedal with only 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.

We added a switchable audio loop in case you use additional stompboxes or other external equipment to make sure the sound of BP1 is never compromised.

The Radio/Wireless input and all outputs use custom-made audio transformers. In general, only the finest components are used in this stellar preamp design.

To make life even easier for you, we designed the BP1 with a power supply that will work anywhere on the planet.

The BP1 is like a magic button, it just makes my bass sound better. It cleans up the frequencies, so my signal comes through clearer and more punchy”

The BP1 signal path

The BP1 features the famous Input Buffer that we have used in our Custom Shop Systems for years. The main function of the Input Buffer is to make your bass guitar sound as if it was connected directly to your amp.
When you use the loop of the BP1, your bass guitar will not be loaded incorrectly from your stompboxes, it will still “see” the Input Buffer.


Jonathan Noyce (Gary Moore)

“The bass preamp that Steen Skrydstrup made for me in 2019 has been a great success. It’s been a game changer, in fact.
The importance of the quality of what you plug an instrument into cannot be overemphasized.
I’m currently using it in my studio at home where it seems to be equally happy”

(Jonathan Noyce, Gary Moore)
