High-Quality Boss Effects

The ME-90 puts a massive library of legendary Boss effects at your feet, offering 7 different categories filled with selections derived from the flagship GT-1000. Everything you need is here, from overdrives and distortions to pitch/mod effects, delays, and high-quality reverbs. You also get 11 dedicated Pedal FX, a looper, and specialised effects such as acoustic simulation and down tuning.

There are 60 effect types in total, with access to over 20 more via Boss Tone Studio. A send/return loop is available for external pedals, complete with the ability to save the on/off status in patches and place the loop before or after amp models in the signal chain.

Premium Amp Sounds with AIRD Technology

Along with its effects, the ME-90 includes amp models ported from the GT-1000 — driven by Boss' advanced AIRD technology for authentic tube tone and touch response. 11 onboard amp types offer everything from clean combo sounds to punishing high-gain stacks, and you can access more selections in Boss Tone Studio. Each amp includes a dedicated cab sound for connecting to a PA or recording device, and you can load three of your favourite speaker IRs to personalise sounds to your taste!

Mr A Howell1st Mar 2024

It’s an all in one pedal board. And it’s analog. Exactly what I’ve been looking for. Easy to use. The YouTube videos really compliment it.

Lots of different effects available with easy adjustment via the dials. There is a learning curve with balancing the volume jump found when switching from manual mode to preset mode that I’m still working on. There are plenty of YouTube videos that offer advice and guidance on patch creation and ways to connect to your chosen output (there is a big difference if you get it riight). Currently using it in preset mode with patches I’ve created or ones I’ve tweaked from the Boss Tone Exchange website. There is more capacity in this than I will ever need so I’ll keep tweaking till I get it right. Already used at band practice and looking forward to using it live at toyr next gig.

As a beginner the item is a bit daunting as it has so many functionalities....and the manual is not great. However after a few YouTube videos and trial and error I can now work most of it...some things still to try! A few loops to jump through to set up the software but again I got there and it's worth it. Overall I think it's great piece of kit!

I am in love with the ME-90. It has given a boost to my playing being able to mess around with the different sounds. For ages I was debating getting the ME-90, so long in fact, the ME-90 came out in the meantime. I have only scratched the surface as I am happy plying with the presets at the moment. It's easy to use straight out of the box, you'll be playing in minutes.

I'm only just scratching the surface of what is possible with this effects unit but it's great so far. There's hours of entertainment to be had just playing with tone settings. I love it.
