Boss GX-1B - Bass Effects Pedal

BOSS GX-1B Bass Effects Pedal & Amp Processor

The BOSS GX-1B is an ultra-portable bass multi-effects pedal and amp processor built for modern players who want pro sound in a compact, go-anywhere unit. Designed as your “daily bass companion” for practice, recording and performance, the GX-1B delivers premium, bass-tuned amps and effects with the feel and responsiveness that keeps your playing connected to the sound. At the heart of it is BOSS AIRD technology, providing authentic tube-style touch response—so your dynamics, attack and note bloom translate naturally whether you’re laying down a tight fingerstyle groove, digging in with a pick, or riding the edge of breakup for vintage vibe.

With 16 amplifier types and over 130 BOSS effects, the GX-1B covers a huge range of bass tones—from clean, punchy foundation sounds to driven, character-rich textures for rock, pop, funk, worship and heavier styles. The flexible routing and adjustable effect order lets you build practical signal chains for real-world playing. And with eight simultaneous effect blocks plus a volume pedal and noise suppression, you can create polished, stage-ready patches that stay controlled and consistent when the band gets loud.

Sound creation is designed to be fast and frustration-free. A high-resolution colour display and intuitive effect category buttons make it simple to navigate, switch effects on/off, and dive deeper when you want to fine-tune. The GX-1B also introduces Gear Suite, a smart way to dial in bass sounds quickly—recall professionally tuned parameter sets with a turn of a knob, then tweak and save favourites for instant access later. You get 99 ready-to-play preset memories and 99 user memories, making it easy to organise patches by setlist, bass, tuning, or genre.

For performance control, the GX-1B includes three freely assignable footswitches and an expression pedal with toe switch. Set them up for simple patch changes and effect toggles, or get creative—control multiple parameters at once for seamless transitions between verse and chorus, or bring in a lead boost without changing your core tone. You can expand control via a jack that supports up to two external footswitches or an expression pedal, and you can also go wireless with the optional FS-1-WL and EV-1-WL.

Connectivity is a big part of the GX-1B’s appeal. Jam along to tracks via onboard Bluetooth® audio, record directly with the USB-C® audio interface, and edit sounds with the BOSS Tone Studio app (macOS/Windows/iOS/Android). You can also download and share Livesets on BOSS Tone Exchange, and personalise your feel further with WAV speaker IR loading. With premium audio performance—24-bit AD, 32-bit DA, 32-bit floating-point processing and 48 kHz sampling—the GX-1B is a serious tool in a remarkably small footprint.

At Guitar World Gold Coast, the BOSS GX-1B is a top pick for Australian bassists who want a compact, reliable all-in-one effects and amp solution that’s ready for lessons, rehearsal rooms, studio work and live stages.
