Historical Context and Positioning in the Range
The AT 112H+ belongs to the GR Bass cabinet lineup focused on "modernity and performance," with a design aimed at a very advantageous power-to-weight ratio. Within the range, the 1 x 12-inch format is often considered the best compromise: compact enough to fit in a car trunk, yet large enough to maintain body, dynamics, and a solid low-end foundation. The BLK Black finish easily integrates into any rig, from the most discreet to the high-end.
Who This Amp Is For
This cabinet is aimed at bassists who want a simple, lightweight, and reliable setup without sacrificing definition. It suits both intermediate musicians and professionals: in the studio for a clean and controlled recording, in rehearsal to hold its own against drums, and on stage for precise sound projection (with or without mic/DI feed depending on your head). Style-wise, it handles everything from funk to rock, including pop, modern jazz, and contexts where a firm low end and clear attack are sought.
Features and Innovations
The GR BASS AT 112H+-8 BLK focuses on essential utility: a 12-inch speaker with a neodymium motor for dynamic reserve, complemented by a 1-inch tweeter whose level is adjustable via a 4-position selector. This control is valuable for tailoring brightness to active basses, new strings, slap playing, or conversely softening the high end with a Precision or flatwound bass. The front-output bass reflex design promotes coherent low-frequency response and better clarity when the cabinet is placed near obstacles. The connectivity is designed for the field, with combo inputs/outputs allowing daisy-chaining to a second cabinet.
Sound Character
The AT 112H+ offers a modern, fast, and defined signature. The 12-inch speaker delivers solid lows and clear articulation in the low-midrange (the area that makes notes stand out in the mix), while the tweeter adds just the right amount of grain, snap, and harmonic detail without making the sound harsh if adjusted carefully. With a sensitivity rated at 99 dB SPL, it responds easily to right-hand playing: dynamic fingerstyle, sharper pick attack, or more percussive slap. Paired with a transistor head, it remains very clean and precise; with a tube head or a more colored preamp, it lets your chain's personality shine through while maintaining a clear and punchy foundation. Regarding artists, GR Bass is used by many modern scene bassists (brand endorsements), aligning well with the "definition, punch, and portability" orientation of this 1 x 12-inch format.
