February 1, 2026 · 2 sources

BOSS announced the GX-1 Guitar Effects Processor and GX-1B Bass Effects Processor on January 16, 2026, describing them as entry-level additions to the GX multi-effects series¹. The GX-1 is designed for guitarists, while the GX-1B is tailored for bassists¹. Both were listed as available now at $229.99¹.

BOSS says the two units share identical features apart from their internal sounds and chassis colors¹. Each offers eight simultaneous effect blocks plus a volume pedal and noise suppressor, adjustable effect order, and a selection of amps and effects¹. There are 99 memories loaded with ready-to-play presets and 99 user memories¹. Hexagon-shaped panel buttons represent effect categories; a tap turns an effect on or off and a long press opens detailed parameters¹. Both units introduce Gear Suite, which BOSS describes as a feature for quick setup of amps and effects, with professionally tuned settings per type and user locations for saving favorites¹. Footswitches and an expression pedal are freely assignable, and wired and wireless external control options are available¹. Power can come from batteries, an AC adaptor or USB¹. Bluetooth and USB connectivity are included, and the BOSS Tone Studio app adds YouTube integration, built-in rhythms, editing and sounds on BOSS Tone Exchange¹.

A review of the GX-1B in Bass Gear Magazine describes the pair as modernized takes on the GT-1, with AIRD amp modeling, built-in Bluetooth and access to BOSS Tone Studio and BOSS Tone Exchange². The review lists the GX-1B as made in Vietnam with 135 effect types, 16 amp types, 48 kHz sampling frequency, 32-bit floating point processing, a phrase loop of 38 seconds mono and 19 seconds stereo, and a color graphic LCD of 320 x 240 dots². It gives dimensions of 307 mm by 149 mm by 73 mm and a weight including batteries of 1.2 kg, or 2 lb. 11 oz². The review states the unit ships with four AA alkaline batteries but no AC adaptor, which is sold separately as part of the PSA-S series, and that it runs for approximately five hours on batteries².
