Description
The GX-1B delivers professional-grade sound and features in an ultra-portable platform for practice, recording, and performance. Premium bass-tuned amps and effects supply endless creative fuel, while the high-res color display, intuitive effect buttons, and Gear Suite tools make sound creation a snap. Rugged, powerful, and remarkably compact, the GX-1B is filled with inspiring tones for every bassist, from beginning players to touring pros seeking an all-in-one travel solution with no-compromise sound.
Pro Tones for Every Player
The GX-1B captures decades of our bass-focused sound development in one versatile processor. Explore 16 highly expressive AIRD amps, complemented by over 130 effects from the vast BOSS library. With adjustable effect order and eight simultaneous blocks plus a volume pedal and noise suppressor, you can easily craft custom setups for playing different music styles and performing specific songs on stage.
Smooth Operation
Whether editing presets or building sounds from scratch, the GX-1B is designed for frustration-free creation. Inspired by the GX-100 and GX-10 interfaces, the hexagon-shaped effect buttons provide a visual representation of the sound categories, and you can use them to turn effects on/off with a tap or access detailed parameters with a long press. You also get 99 memories loaded with ready-to-play presets, plus 99 user memories for storing your custom sound creations.
Build Sounds Fast with Gear Suite
The GX-1B introduces Gear Suite, a powerful new feature for dialing in amp and effect sounds fast. Each amp/effect type contains multiple factory Gear Suite settings, letting you recall a complete set of professionally tuned parameters with the turn of a knob. You can also edit effect parameters to taste and save favorites in user Gear Suite locations for instant access to personalized settings.
Performance Freedom
Once you've crafted your tones, grow your expressive range on stage with advanced real-time control. Assign the onboard footswitches and expression pedal to control anything you can imagine-from basic effects on/off to adjusting one or more parameter targets at once-and go even further with wired and wireless options for external control. The GX-1B also offers three flexible power options (batteries, AC adaptor, or USB), allowing you to practice and perform anywhere.
Your Daily Creative Partner
The GX-1B flows wherever your creativity takes you. Interface with a mobile device or computer via Bluetooth or USB to jam with songs and record tracks in a DAW. When you're ready to dive deeper, BOSS Tone Studio is your ideal partner. Use the Session feature to play along with YouTube songs and lessons, complete with AB repeat and speed adjustment. Hone your skills with a metronome and rhythms. And access BOSS Tone Exchange within the app to stay inspired with pro sounds. Editing tools are also on hand to fine-tune effects and organize sounds for later recall.

Protect your investment with the Long & McQuade Performance Warranty
A warranty can be a very important factor when making a buying decision. Because repairs can be very expensive in terms of parts and labour costs, manufacturers usually only provide one year limited warranties that generally only cover items that malfunction due to a manufacturer’s defect. With an important purchase such as a musical
instrument or piece of studio gear, however, many people want to have the peace of mind in knowing that their investment will be protected should the product no longer be performing at 100%.
Because of this, Long & McQuade provides our customers with a FREE one-year Performance Warranty on most of our products. The Long & McQuade Performance Warranty supplements the manufacturer’s warranty to ensure that our customers receive complete “no hassle” warranty coverage within their first year.
How does the Long & McQuade Performance Warranty differ from most manufacturers' warranties?
- Performance Guarantee: Normal wear and tear is covered, so your product will be performing as well as the day you purchased it for the entire duration of the coverage. Band and Orchestral Performance Warranty does not include replacing pads or cleaning for woodwind instruments, unless deemed necessary by our repair staff. Ultrasonic cleaning for brass instruments will be provided if deemed necessary by our repair staff, but is not routinely offered under the Performance Warranty.
- Product Replacement: If your product cannot be fixed or costs too much to fix, we will replace it with the equivalent model for no additional charge. If this is not possible, a full refund will be provided.
- No Lemon Policy: Your product will be replaced should the same problem occur multiple times.
- Convenient: Easy drop off and pick up of the product at any Long & McQuade location.
- Guitar Setup: Guitars purchased at Long & McQuade come with 1 free setup, to be redeemed within 1 year for new guitars and 90 days for used guitars.
- Loaners Available: A loaner product may be given while the product is being repaired.
- Power Surge Protection: Your product is covered even if damaged from a power surge.
- Accessory Coverage: Any peripheral devices or accessories that come with your product (i.e. foot pedal, case) are also covered.
- Commercial Use Coverage: Music and recording professionals who purchase gear for “heavy-use” commercial purposes will still be covered.
Long & McQuade reserves the right to restrict the purchase of additional years of Performance Warranty. Used products come with a 3-month Long & McQuade Performance Warranty. Some products (i.e. computers, software, cymbals and other items) are covered only by the manufacturer‘s warranty. Consumables (i.e. strings, reeds, drum sticks, batteries, tubes, cross faders) are excluded as they are designed to be replaced. Cosmetic Damage, Accidental Damage, or problems caused by Humidity or Temperature Issues are not covered. Speakers damaged by overpowering are generally not covered. Our coverage does not provide compensation for loss of use. As of June 2018 the Performance Warranty is no longer transferable. The warranty is only valid in Canada.
Purchasing additional years of coverage
Some manufacturers provide warranties for longer than 1 year; however, these are usually limited warranties that do not provide the same coverage as the Long & McQuade Performance Warranty. Customers interested in more complete and convenient (but not necessarily longer) coverage are still able to purchase additional years of the Performance Warranty.
If you are interested in receiving this coverage for longer than one year, you have the option of purchasing additional years of the Performance Warranty. The pricing is as follows:
- NEW products: Starting at 4% of the current new selling price to double the warranty from 1 year to 2 years. Starting at 4% for each additional year.
- USED products: Starting at 4% of the current new selling price to increase the warranty from 3 months to 1 year. Starting at 4% for each additional year.
- GUITARS: 4% of the current new selling price to double the warranty from 1 year to 2 years. 4% for each additional year. $45 maximum. An additional free setup is not included with additional purchased years of Performance Warranty.
- BAND and ORCHESTRAL instruments: 4% of the current new selling price to double the warranty from 1 year to 2 years. 4% for each additional year.
