Boss ME-90B Bass Multi-Effect
Product no: 9000-0125-4632
Product information
General
The BOSS ME-90B kits out bassists with a powerful multi-FX processor loaded with 61 effects and 10 AIRD preamps. Equipped with a small army of controls as well as a built-in expression pedal, this potent tool can be effortlessly operated using your hands and feet and unlocks a treasure trove of options that help get your creative juices flowing. You're free to plug the ME-90B into your bass amp, hook it up to your audio interface, or connect it directly to the PA system. There's not even any latency, meaning you can stay fully focussed on your bass lines.
The ME-90B: Everything You Need
Ideal for gigging bassists, the classic BOSS ME stompbox-style control lay-out puts every function and setting within easy reach — no menu-diving required. Every effect category is backed up by dedicated controls for the most-used parameters, while the Manual Mode enables you to turn categories on and off entirely using the footswitches. In Memory Mode, you can instantly access 36 custom multi-effect patches and, so you can easily keep track of it all, every footswitch is illuminated by a differently coloured LED. If you want, you can also assign a fixed colour to any of the LEDs.
BOSS Bass Effects Library
The fat stack of effects that the ME-90B serves up come from the BOSS Bass Effects Library and have been divided into six categories. For proper tone-sculpting, you get a range of compressor, pitch-shifters and filters. For injecting character, you get drive and synth effects, while your bread-and-butter effects include a host of modulation effects, delays and reverbs. Want to add your favourite stompboxes to the mix? No problem! Simply connect them to the integrated FX loop and mix them in as needed with the Blend pot.

Boss ME-90B Bass Multi-Effect
Loving the ME-90B. Still working on finding 'my' sound on it but discovered Ampeg do their own IRs so have an SVT DI-out on the output and with the Concert SVT preamp or the flip-top it sounds awesome. But also sounds good with an 8x10 IR as well. Also loving the Fat Tube 'Orange' amp. Used mostly for Church band work, I've started dropping a bit of Drive to fatten out the sound which they love, the FoH sound guys love the clean DI and the tone through the PA, going to try running an EH Mono Synth through the send/return and see how that works. Using it on the FX Return on my RM500 amp it sounds great with the SVT DI IR. I like that I can have 2 compressors with different settings, one with really long sustain. Love the Freeze on the pedal, used when we have no keys and need a drone sound. Shimmer is nice, but not quite 'there' for me. Still loads of experimenting to do and incorporate my other pedals. OC-5 imho is better than the ME90B octaves, but the detunen and pich shift are useful. All in all I'm a very happy bunny. :D

Boss ME-90B Bass Multi-Effect
This pedal is fantastic. It does everything from acting as a clean DI box, with adjustable gain and EQ, up to sounding like you have a synth playing along with you - AND looping. I've only used the preset sounds so far. Out of 36 I've found 6 which are so good I can't imagine being able to come up with anything better - so not yet into editing sounds and saving them. I was initially very attracted by the no-menu knob and footswitch based editing interface but I may never need it! Inspirational sounds, reinvigorated my relationship with Bass!!

Boss ME-90B Bass Multi-Effect
Blimey, the BOSS ME-90B is good! I bought one from Bax a month ago and have been really blown away by the pedal. It is super-easy to dial in a tone that works and save it to one of the user preset slots. Ok, there’s no screen, so you have to remember which preset, but to be honest, I’m a bassist, I don’t use a different one for each song, so it’s not that much of a hardship!
I particularly like the fact that you can create just the right tone by twiddling knobs, rather than having to menu-dive. It’s easy and intuitive to use and the results are great!
For the money, the ME-90B is well worth it. I actually wish I’d bought one sooner!

Boss ME-90B Bass Multi-Effect
I wanted to update my 27 year old Zoom 3000B Bass Multi Effects and, after researching what was currently on the market, I chose the Boss ME-90B Multi-Effect unit.
I’m absolutely delighted with it and it’s brought a new lease of life to my bass sound and freshened up my playing.
I’ve bought various items of gear from Bax before and didn’t hesitate to buy from them again as they carry a good range of product at competitive prices and deliver quickly.

Boss ME-90B Bass Multi-Effect
Ik heb voorheen verschillende Boss multi-effecten gehad, waaronder de ME-8B, GT-6B en de GT-10B. Deze heb ik maar steeds kort gehad omdat ik toch eigenlijk maar weinig effecten nodig had en de meeste geluiden veel te steriel vond klinken. Dus voor aanschaf van de ME-90B had ik dan ook de nodige twijfels. De stap toch gewaagd omdat ik nu toch wel wat tone shaping wilde gaan doen en bepaalde effecten via losse pedalen laat komen. Ik was op zoek naar een oplossing in 1 apparaat zonder teveel ellende met menu's. Samengevat is de ME-90B een uitkomst. In vergelijking met oudere units zijn de versterkermodellen heel bruikbaar en kan ik met dit apparaat heel makkelijk subtiel effect toevoegen. Ook snel schakelen gaat erg eenvoudig zonder vertraging of gedoe. Let wel, dit apparaat doet niet perfect een Dark Glass pedaal na en in principe zijn ook de effecten van bijvoorbeeld TC Electronics echt wel iets beter (vooral de octaver), maat de Boss is meer dan goed genoeg. Voor mij reden om een aantal losse pedalen de deur uit te doen en deze unit standaard te gaan inzetten. Complimenten voor Boss.

Boss ME-90B Bass Multi-Effect
Geweldig toestel. Gemakkelijk te bedienen on the fly.
Klanken en effecten top.
Laag stroom verbruik zodat deze geen extra adapter nodig heeft als je al een powerbank hebt. Ook te gebruiken met batterijen.
