Once again, BOSS is thinking of bassists by offering its powerful ME-90 multi-effects version in B version (for bass).

Benefiting from the latest technologies resulting from the research of Japanese engineers, including the AIRD* engine, the ME-90B allows you to create YOUR sound through 10 specially designed preamps and 6 effects sections bringing together 61 of the best BOSS effects.

The most useful effects are represented: compressor, limiter, octave, pitch shift, delay, reverb, phaser, wah, drive and distortion, modulation, without forgetting the expression pedal allowing you to control some of them.

The most demanding musicians will be able to fine-tune their sound down to the smallest detail and save it in one of the 36 user memories, in addition to the 36 presets already integrated into the machine.

Moreover, pedal users can also connect their equipment via the integrated effects loop (Send/Return) located on the back of the case.

Navigation is intended to be as simple and uncluttered as possible thanks to the 8 switches allowing you to navigate through the different banks, activate the effects of your choice, use the integrated tuner and even switch to Manual mode to control the effects chain as if you found yourself in front of a pedalboard.

In terms of connectivity, the ME-90B is not left out since we find a 6.35mm jack input, a dual Mono/Stereo 6.35mm jack output as well as a balanced XLR output. You can also plug in a headset via the 3.5mm jack and work silently at any time of the day or night.

A USB-C port allows you to connect to a PC/Mac and benefit from Livesets created by users around the world, or even record the processed signal directly into your favorite production software.

There is also a dedicated port for the BT-DUAL adapter (sold separately) for jamming over your favorite tracks or modifying the built-in sounds.
