Fast Sound Creation
With its knob-driven interface and diverse effects selection, the ME-90 lets you build configurations and tweak tones with the ease of a stompbox-filled pedalboard—without the hassle of fastening tape, power distribution, and multiple connection cables. Just dial up an amp model or effect type within a category and turn the knobs to get the sound you want. There are 36 preset patches with ready-to-play pro tones, plus 36 user patches for storing your custom creations.
Flexible Real-Time Control
The ME-90 features eight footswitches with smooth, quiet operation and an expression pedal with an integrated toe switch. Use Memory mode to call up complete patch setups with the footswitches, and then switch to Manual mode for direct on/off control of each effect category within the patch. The footswitch LEDs light in different colors for quick identification in the heat of a performance. It’s also possible to set all LEDs to light in a fixed color for each mode if desired.
High-Quality BOSS Effects
The ME-90 puts a massive library of BOSS effects at your command, offering seven 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 specialized 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.
