Scaling new heights in perfecting the tonal capabilities of magnetic pickups, the Delano Sonar bass preamp series is designed for just one purpose: Making a good tone even better.

As an integral part of any active bass guitar, an active EQ has to fulfill countless requirements regarding strength and clarity in tone, power consumption and installation. To meet this challenge perfectly, the time has come for a new onboard preamp: Sonar.

This smart powerhouse delivers the real thing: rocksteady bottom, cutting midrange and naturally brilliant high end. Whether adapting its tone to match the surrounding acoustics, enhancing versatility or increasing your musical expression, this preamp always feels like a natural extension, preserving all the benefits of passive operation: uncoloured, true and focused sound. Comparing the flat-set sound to bypassed full passive action you´ll detect no difference. Matchless. And with its perfectly matched band-pass filters and separated amplifier stages, adjustments stay predictable at any time without overpowering tone.

The Delano Sonar onboard preamp is housed in a sealed slim-box, which provides easy, space-saving installation and secure insulation to other electrical components. Its minimal power consumption lets you forget where your battery-box is - make a guess?

Please Note:Though limited to only a few control configurations we carry potentiometers to allow you to create a control layout to fit your bass. Delano Sonar preamps come with prewired tone pots. Volume pot (push-pull) and balance pot are included.
