EBS Microbass 3 Preamp/DI


The Swiss Army knife of Bass Preamps.  

The EBS MicroBass 3 is a 2-channel preamp, built exclusively with premium components. It is engineered by EBS in Sweden with technologies from the famous HD360 and Fafner II amplifier designs. The preamp operates at a signal level equal to a professional mixing console (+/- 15V)which gives you plenty of headroom. The high signal level makes it suitable to use as a preamp in combination with any type of power amp.

Run the Clean and Drive channels in series or parallel. Use the dual balanced XLR-outputs to tap the signal post and pre EQ at the same time. If you run the Effects loop in stereo mode, the balanced outputs become a Left and Right output instead. With 10 Mohms input impedance, it handles any type of bass – passive, active or with piezo pickups.

The built-in tuner makes it easy to tune between songs without the need of an external device. The MicroBass 3 also carries an onboard compressor, similar to the one found on several EBS amplifiers, and several more features.

The analog EBS MicroBass 3 delivers your tone – every time.
