Gr Bass AT CUBE 350 BLK BLACK

Historical Context and Positioning in the Range

The GR BASS AT CUBE 350 BLK aligns with GR Bass's philosophy: offering modern, compact bass amps focused on performance, with "plug and play" ergonomics but real adjustment range when you want to sculpt your tone. Within the range, this combo clearly targets bassists who want an all-in-one format (head + cabinet) that is easy to transport, while retaining a full preamp section (tuner, VU meter, DI, loop, filters) adapted to current stage requirements.

Who This Amp Is For

This combo is ideal for beginner to advanced bassists seeking a versatile amp capable of covering daily practice, rehearsals, and gigs where DI output to the front of house is used. Its 1x12 format makes it particularly relevant for styles demanding clean and clear lows: pop, funk, modern rock, gospel, electric jazz, contemporary music, and "pedals + DI" setups. Thanks to the headphone output and auxiliary input, it is also well suited for home work without sacrificing a true amp feel.

Features and Innovations

The control panel emphasizes efficiency: Gain and Master volume to manage overall level, a Deep Filter to enhance low-end depth, and a 4-band EQ complemented by selectable frequencies for mids (Mid-Low and Mid-High) to precisely adjust attack, presence, and bass placement in the mix. For the stage, the adjustable DI output with Pre/Post switch (choice between raw or EQ'd signal) and GND Lift to reduce hum are appreciated. For comfort: integrated tuner and VU meter, mute footswitch, effects loop (send/return) to insert modulations, delays, or multi-effects after the preamp, and a handy 9V DC 300mA output to power an essential pedal in a small setup.

The Sound

Built around a transistor preamp, the GR BASS AT CUBE 350 BLK favors a fast, defined, and dynamic response, with lows that remain clear even when the volume is pushed. The 12-inch speaker provides body and impact, while the 1-inch tweeter (3-position setting) allows adding more or less brightness for fingerstyle, pick, or slap techniques. The rear bass reflex helps to add fullness in the low frequencies, and the equalization (notably the mids with selectable frequencies) facilitates fine-tuning: scoop for a modern sound, or conversely add mids to cut through a rock mix. Result: a combo capable of going from very clean to a more aggressive grit via gain, while staying coherent and controllable on stage and in the studio.
