    Product Description

    The EBS-MB3 is a preamp with two channels, produced using high-end materials and parts. You’ll have plenty of headroom to play with as the preamp works at a signal level that is equal to a pro mixing console. This higher signal means you can use it as a preamp alongside any type of standard power amp.

    Useful Built-In Tools

    A number of in-built features separate the EBS-MB3 from the rest. The two contrasting channels (drive and clean) can be used either parallel or in series. The dual balanced XLR-Outputs can tap the signal post and pre-EQ simultaneously, while 10 M Ohms of Input Impedance let it handle absolutely any kind of bass. An onboard tuner means you can tune without needing another device. This is a seriously versatile piece of kit!
