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.

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. Volume Push/Pull & Blend Pot are enclosed.

Excellent Pre Amp
By Tommy
I have basses with Bartolini,and Aquilar Pre's and the Delano is just a good as any I have mentioned, it is VERY clean and transparent, so you really hear what your bass really sounds like. It also have a lot of tone shaping.and you can boost the treble, with out it getting harsh...
The mid selection is great, I can't say enough good things,other that you will not be disappointed.
I'm currently using this pre with a pair of Bartolini Classic Dual Coil Hum cancelling Soap bars...great combo

Top shelf pre-amp!
By Jack Blackwell
I installed this in a 2003 Carvin LB75A fretless when the original preamp sounded like crap next to a very similar Carvin fretless with identical pickups but an Aguilar preamp on board. The tone gets positive comments from even non=musicians and it's quiet and quite linear in its operation. Recommend? Yes, with no reservation.

Delano Sonar 3-band bass preamp
By Nick Salazar
I installed it in a Yamaha TRB1006 (six string bass) and it greatly increased the output, punchiness, and overall ability to cut through any mix. This preamp adds great clarity and piano-like tone to any bass. The only thing I'm missing to make this an unparalleled bass are the Delano pickups which I will absolutely get. You will NOT be dissapointed with Delano as they are hi-fi German-grade products that are sought after by only the best high-end bass crafters!
