Historical Context and Positioning in the Range
The AT CUBE 112+ is part of GR BASS's modern solutions focused on performance/weight, with a very current approach: maximizing power handling and projection while minimizing bulk. Within the range, this 1x12 format is positioned as an "all-round" choice for bassists who want a single cabinet capable of covering many situations and that can easily evolve into a larger rig by adding a second cabinet.
Who This Amp Is For
This cabinet targets intermediate to professional level bassists looking for a speaker that is easy to transport and serious enough to handle real band volumes. It is comfortable for rehearsals, studio use (to enjoy a more "authentic" listening experience than a simple simulation), and on small to medium stages for mic'd playback or PA reinforcement. Its 12-inch configuration makes it suitable for many styles: pop, rock, funk, soul, modern jazz, gospel, and any context where a clear bass presence in the mix is desired.
Features and Innovations
Here, no channels or built-in effects: the idea is to offer a pure cabinet, reliable and efficient, that lets your amp head, preamp, or pedals handle the tonal coloration. The key feature is the 1-inch tweeter with 4-position level adjustment, very useful for switching from a softer "old school" sound to a modern brightness for slap, harmonics, and pick attacks. The front-facing bass reflex load enhances the sense of projection and helps maintain a solid low-end response even when the cabinet is placed on the floor in live conditions.
Sound Character
With its neodymium 12-inch speaker, the GR BASS AT CUBE 112+ aims for a fast and articulated sound: firm lows, a present low-midrange to "hold" the band, and enough definition so each note remains intelligible. The high sensitivity promotes an immediate response feel: at equal power, the cabinet "speaks" quickly and gives a sense of ease. The tweeter, adjustable in 4 positions, allows fine tuning of the high frequencies: more mellow for a round, vintage fingerstyle, or more open for a modern, punchy, and detailed sound. It's an excellent choice if you want to hear the character of your instrument and preamp rather than a cabinet imposing too strong a coloration.
