Boss ME-90 Multi-Effects Processor — Flagship Tones in a Stompbox-Style Floor Unit
This multi-effects processor is Boss's most advanced ME-series all-in-one guitar unit, replacing the ME-80 in 2023. Eleven onboard AIRD amp models and 60 effects ported from the flagship GT-1000 run through 24-bit AD/DA conversion, 32-bit floating-point processing, and a 48 kHz sampling rate. Players can dial in tones without menu diving thanks to the knob-driven, stompbox-style interface. With 36 preset patches and 36 user patches, both ready-to-play rigs and custom setups are possible.
AIRD Amp Modeling and IR Loading — What Sets This Unit Apart
Boss's AIRD (Augmented Impulse Response Dynamics) technology models tube amp behavior and touch response with notable realism. Eleven onboard amp types span clean combos through high-gain stacks, each paired with a dedicated cab simulation. The IR Loader software allows loading of three user speaker IR slots for third-party cabinet captures.
