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!
