GR Bass

Pure drive

The Pure Drive is a decidedly versatile Preamp designed for the most demanding bass players but suitable for everyone thanks to its ease of use that allows you to always have all the characteristics of the GR sound in ultra-compact size.
The Pure Drive is equipped with a 4 band eq with 4 selectable frequencies on the mids and deep and bright filters.

Furthermore, it is completed by an “Overdrive” section which, with its volume and dedicated drives, will allow you to obtain light saturations up to massive distortions.
The Pure Drive is also a professional tuner with display and a D.I.
All the components are carefully selected to offer a top product. It is completely made in Italy and is designed and built by a bassist for bass players.
