Pros and cons

Pros

The combination of amp models, IR loading and multiple effect categories provides broad sound-shaping options in one processor.
Eight multifunction footswitches, an expression pedal and dedicated knobs offer several hands-on control methods.
36 user patch slots give players room to save custom setups alongside 36 presets.

Cons

At 7.9 pounds and over 21 inches long, this unit is a substantial floorboard rather than a small single-effect pedal.
Wireless mobile connectivity depends on an optional adaptor, adding a separate item to obtain for that workflow.

Frequently asked questions

Can the ME-90 run on batteries?

Does it include wireless Bluetooth connectivity?

No included adaptor is stated. The listing describes Bluetooth audio and MIDI as available through an optional Bluetooth Audio MIDI Dual Adaptor.

How many patches can be stored?

The listing specifies 36 ready-to-play preset patches and 36 user patches for custom setups.

Can I edit the sounds with software?

The listing says BOSS Tone Studio can be used to edit parameters and change amp and effect types. It also describes IR loading.
