## Overview

The BOSS GT-1B Bass Effects Processor delivers flagship-quality bass tones and effects in a compact, rugged design. Featuring a powerful sound engine, real-time control switch and expression pedal, and up to 7 hours of battery-powered play, it’s engineered for both stage and studio. With intuitive Easy Select and Easy Edit functions plus free downloadable patches from BOSS Tone Central, it’s the ultimate tool for bassists craving professional versatility and portability.

## Description

GT-1B Bass Multi-Effects Processor Premium BOSS sound engine specially tuned for bass The GT-1B gives bass players a massive range of pro tone-shaping power in a small & robust package. Backed by BOSS’s flagship sound engine, you have full access to a huge selection of bass-optimized amps and fx for stage and studio playing. The streamlined interface lets you dial in sounds fast, while the onboard control switch & expression pedal enable you to adjust multiple effects in real time. And by connecting to BOSS Tone Central, you can download new patches, editing software, & more.

Review: Big bang for the buck! - You really can't beat this unit for ease of use, features, or sound quality. True, some of the effects aren't quite exactly like the vintage analog boxes they emulate, but it's surprising how close they actually get. And most of the dozens of effects you can choose from are stellar. The internal routing is well thought out as well, with copies of some effects showing up in other areas just in case you want your phaser in front of your distortion. Very cool and compact, I feel like I've only scratched the surface after a couple of weeks. I especially like how in "manual" mode, it's like having eight discrete pedals at once, with all the controls just where you'd expect them with ZERO menu diving!
Review: Finally, an escape from the horror of menu-driven pedals - I love this thing. Truly. Every control is right there, easily adjusted, easily triggered on and off, and the memory preset saves remember everything. In manual mode, experimenting and/or tweaking is WAY easier than a menu-driven system. It runs on batteries or from a wall wart, so it's easily portable. It seems to be very quiet, the only thing I noticed is that when the compressor/expander is running at its highest gain, there is some noise, but it's unclear to me if that's coming from the pedal, or just the ambient noise from the instrument. In any case, it's an edge case and I don't consider it a serious issue. The quality of the effects are very high - that's key here. It's not just convenient, it makes great output. I've been playing electric rock and blues for 50 years as I write this, and this is easily the best f/x system I've used to date. Highly recommended.
