Boss GT001 Guitar Effects Processor

This second hand guitar effects pedal is in great condition

The Boss GT-001 is a compact and powerful desktop guitar effects processor that brings the flagship GT-series tones into a small, studio-friendly unit. Designed for home recording, practice, and mobile musicians, the GT-001 offers a deep selection of amp models, effects, and USB audio interface capabilities, making it a versatile tool for guitarists who want pro-level tones in a sleek and portable package.

Build Quality & Design

The GT-001 is built with a modern, lightweight design that fits perfectly on a desk without taking up much space. The sleek black finish, intuitive control layout, and bright LCD screen make navigation easy, though menu diving is sometimes necessary for deeper editing.

While it lacks the stompbox-style footswitches of larger multi-effects units like the GT-100, it makes up for it with a touch-sensitive panel and assignable knobs. The lack of an expression pedal is a downside, but an external one can be connected via the control/expression input.

Tone & Effects

At the heart of the GT-001 is Boss’s COSM modeling technology, delivering amp and effects models inspired by classic tube amps and legendary pedals. The unit provides:

• Pro-level amp simulations, including Marshall, Fender, Mesa, and Boss’s own unique high-gain models.
• Over 100 effects, including drives, modulations, delays, reverbs, and pitch effects.
• Dual signal paths, allowing for layered tones or direct recording versatility.
• Guitar-to-MIDI conversion, letting you trigger synth sounds from your guitar.

The amp modeling is very solid, especially for clean, crunch, and mid-gain tones, though some high-gain users may prefer additional tweaking for a more organic feel. The effects quality is top-notch, as expected from Boss, with excellent delays, reverbs, and modulations.

Connectivity & Recording Features

One of the GT-001’s standout features is its USB audio interface, allowing for direct recording into a DAW without needing extra hardware. Additional connectivity includes:

• Stereo 1/4" outputs for external amp or PA connections.
• XLR mic input with phantom power, making it great for vocal or acoustic guitar recording.
• AUX input for backing tracks.
• MIDI and external control pedal support.

The GT-001 also comes with Boss Tone Studio software, making patch editing easier on a computer. However, the learning curve can be a bit steep for first-time users.

Pros:

• Compact, desktop-friendly design
• High-quality amp modeling and effects
• USB audio interface for direct recording
• Guitar-to-MIDI function for synth sounds
• Dual signal paths for creative routing
• XLR mic input with phantom power

Cons:

• Menu navigation can be complex for beginners
• High-gain tones require extra tweaking

The Boss GT-001 is an excellent choice for home recording, practice, and sound design. Its compact size, powerful effects, and USB recording capabilities make it a studio-friendly powerhouse. While it lacks the footswitches of a full multi-effects pedalboard, it excels in flexibility and tone shaping for guitarists who prefer a desktop unit.

If you're looking for a portable, high-quality multi-effects processor with great recording features, the GT-001 is a fantastic investment.
