Bass amp head
With its ultra-small size/weight (1.9kg) inversely proportional to its efficiency, the GR BASS One 350 Head BLK is a transistor head extremely well positioned in the nomadic bass amp segment, developing 350 watts RMS at 4-ohm or 170 watts RMS at 8-ohm.
Intuitive and efficient, the One 350 offers a multitude of textures thanks to its exhaustive equalization and various highly efficient filters (which can be deactivated with the Pure Witch). Its connectivity is not to be outdone, with a headphone output, an Aux In input for connecting a tablet or smartphone, and a D.I. output.
