BOSS ME-90B Bass Multi-Effects | All-In-One Bass Processor | 10 Onboard AIRD Amp Models | 61 Effects from the BOSS Bass Effects Library | 8 Multi-Function Footswitches & Redesigned Expression Pedal

I’ve owned the Boss ME series multi-effects (bass and guitar) since the 50 versions. Excellent value and a good way to learn/understand pedalboard builds. I particularly like the foot switches on this series: Sturdy and easy to press. If you’re looking to spend as little as possible, the the ME-50B will do. The ME-80 adds a USB port, but there’s no dedicated bass version of this model. The ME-90B adds XLR Out, now we’re talkin’. Run that to the FOH and the ¼" jacks to stage/monitor amps. Four AA batteries are included, but I recommend figuring in the cost of a power supply (PSA-120S). The best deal I’ve found for a non-OME version is the SmallSpark Adapter for Boss PSA-120S at ⅓ of the cost. You’ll also need a case (CB-ME80). If it’s not in the budget, then you can pull a starving musician move and duct tape the box for reinforcement. You’ll also need to download the latest software and six documents (Read Me and Setting Up hard copies included) at the Boss support site: Startup; Reference; Parameters; Tone Studio; EV-1 and FS-1 Connections. A card with a QR code is included that will take you to www.boss.info/start when scanned to connect with support. The ME-90B has extensive flexibility and then some. In fact, to keep the numerous variables manageable, I create 5 go-to patches: Default (everything off); Clean (little reverb); Rhythm/Bounce (little distortion); Lead (overdrive) and Acoustic Simulation (12-String Guitar/Stand-Up Bass). This typically covers 90+% of what needs to be done. Creating specialty patches is not an issue with the ME-90B because it’s so versatile. So getting lost in choices is an easy thing to do. Just remember you’ll never finish, you just stop. After I’ve got a patch all set to go, i.e. I decided to stop, I just name it the title of the song and store it in order of performance in a separate bank. All set and ready to go for the gig. Basically, the ME-90B is an affordable and versatile multi-effect unit that steps up-to-the plate for professional performance. Money well spent for musicians of every playing level.

This Boss ME90B is just awesome and amazing...no lag time in processing of bass notes to process chain. LOVE THIS PRODUCT. Specing the weekend getting familiar with my new processor and I am in love with this gadget.

I am blown away by how good the effects sound on this rig. It has everything I need for effects, and I love that it can function exactly like a custom-built effects board, or as an array of saved effect combos in its memory mode. I agree with all the other positive reviews and don't have much to add, but I did want to make two recommendations: one, the bluetooth add-on card is a must, at least for me. It allows one to control the effects and saved configs right from a mobile device, but it also allows for streaming music through the board, which is awesome for breaks during gigs. The second is to recommend this padded case: https://a.co/d/935OG6h. If the link isn't allowed, search for DJ controller case bag by IBVIVIC. The smallest of the 4 sizes (20.5" x 11.8" x 5.9") fits this effects board as though it were made for it. I was going to purchase the one recommended in other reviews, but it looked bulky and larger than it needed to be for this board. The DJ case is just right, but still has enough padding to protect the board, and it has some handy pockets for AC adapters, cables, product manuals etc.

Great board. Easy to use and set up

I agree with the other reviewer who said that this thing is just too complicated. Who thinks up this stuff? What kind of engineer. Just amazing. Hold down this button, press that one. Click this one. Twist that one. User presets. Banks. Flashing lights. What utter nonsense! Does anyone actually play their instruments these days, or do they just prefer pressing buttons and watching lights blink?

This pedal is amazing. Very clear, fairly easy to use

Great! All that I expected. The item arrived on time. Thanks

Excelente producto, impecable llego. Sin fuente viene, pero con 4 pilas de 1,5Volts, funcionas miy bien. Si disponaes de 8 pilas recargables, es suficiente para el uso diario. Fundamental conectarlo usando las entradas y salidas SEND y RETURN de tu amplificador, saltando todo el pre y la ecualizacion y efectos del cabezal de bajo o equipo. Ahi tenes el maximo partido de su sonidos.

発送案内の通知が分かり難かったが無事到着しました。

Fue muy rápido el envío y hoy mismo la conecté, la verdad es que estuve jugando con ella y conociéndola en perillas y en la app BTS, la cual necesitas tiempo para encontrar ese sonido que buscas, pero es sencilla de usar y muy versátil en las posibilidades para el bajo

Muy divertido de usar tiene muchos efectos y es muy fácil de hacer tus propios memorias de combinaciones de efectos, además tiene loop de efectos y puedes conectar otros efectos

Muy buena, muchas mejoras respecto al modelo previo, el ME50B
