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. The SONAR 3MS (MS = Mid Selection) is the first really compact preamp design which offers the great advantage of selecting different mid frequencies.Now it is available as MS/E-version (E = External switching), which provides dialing center-frequencies from the control panel of your bass with a three-position toggle switch.

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: SONAR preamps come with prewired tone pots, & toggle switch. Volume Push/Pull & Blend Pot are enclosed.

I just had this preamp installed in my Peavey Cirrus Rudy Sarzo Signature four string (circa 2011 model - the reissue that never got supported). That bass originally came with an 18 V preamp that would overpower the soundboard (or at least the sound board operator) whenever I would run direct.

This little gem was the perfect solution. My bass always sounded “good,” but now it sounds AMAZING! It is incredibly versatile, achieving great tone and balance across the board. I wish I had this years ago. I am a new convert!

I bought this product to match my pre-installed Delano humbuckers on my TBC bass. I couldn't be happier by the result. It's exactly as advertised. Responsive, useful, balanced. Tone-wise it's very versatile in the active mode, specially with the toggle switch for the mid frequencies, and bypassed by pulling the volume knob, there's no difference in volume. Delano makes great products. This is no exception. The Pickups are great as well.
