Under the hood, this hybrid amplifier combines two 12AX7 tubes in the preamp with an efficient Class D power amp. This combination delivers the warm, rich tonal characteristics of tube technology, complemented by the powerful and reliable performance of a modern power amplifier.

Full control over your bass sound

The GROOVE 800 features a single channel and an intuitive control panel that lets you quickly dial in your desired tone. In addition to the bass, treble, and master volume controls, there are separate controls for both the low and high midrange. This allows you to precisely tailor the sound to your instrument, playing style, and musical context.

The Deep and Bright switches let you emphasize the low and high frequencies, respectively. The mute function allows you to temporarily mute the output signal, for example, when you want to tune your instrument or switch basses.

Additional Sound Options and Extensive Connectivity

For a more pronounced sound, the GROOVE 800 offers a drive function that lets you add extra character and distortion to your bass part. You control the amount of overdrive with the gain knob. In addition, the Mid Scoop function—which is linked to the drive section—lets you choose a more pronounced tone with less emphasis on the midrange.

This amplifier head is also well-equipped in terms of connections. The effects loop with pre/post switching offers flexibility when integrating external effects gear into your setup. Via the DI output, which features its own volume control, you can send the signal directly to, for example, a mixing console, PA system, or audio interface.

Two aux inputs are available for playing backing tracks and other external audio material. If you’d rather play in peace and quiet, you can plug headphones into the headphone output and adjust their volume separately.

This makes the GRBass GROOVE 800 a compact, powerful bass amplifier head with a wide range of sound options and practical connections for live use, at home, and in the studio.
