Introduced in 2008 we are proud when looking at the versatile usage of the GR-1 on various CD productions of famous guitarists. Looking back, guitar legend Uli Jon Roth was the first who explored and integrated this new way in his playing. He gave us invaluable suggestions for the optimization of the device. Today the GR-1 is still our top model, that is applied by many guitarists worldwide.
Any electic guitar with steel strings can be used, even accustic guitars. The GR-1 is driven by the output of the selected pickup. Piezo's with preamplifier work fine too.
The floor box can easily be integrated in any effect pedal case. A standard mircophone stand can be used. A 6,3 mm stereo cable connects the floor box with the gooseneck. The LED in the head iluminates the fretboard. The blue and red color indicates the harmonic selected mode. The brightness shows the intensity of the driver signal.
Handmade in Germany: We only use approved high quality components. Robust Hammond diecast zinc enclosures labeled with high quality scratch resistant aluminium plates. GR-1's are robust and durable even for extensive stage usage. Each GR is manually adjusted before shipping to reach its maximum power and efficiency. We also provide GR-1 customizing on demand.

Our compact model introduced in 2011: It provides great feedback like the GR-1 and offers many of the GR-1 functions to a very interesting price point!
All in one, no separate floor box. Control of harmonics with a slider switch at the head. Comfortable power control directely at the gooseneck. The blue LED in the head iluminates the fretboard. Like the GR-1 the brightness shows the intensity of the driver signal.
The GR-Junior has been developed further! The GR-Junior II is available now. It takes all approved functions of the first GR-Junior which is replaced by model II now. The new design has now a robust Hammond diecast zink enclosure like the GR-1.
Main differences between the GR-1 and the GR-Junior
The GR-1 has more power by its stronger magnetic field. Its head and gooseneck dimensions are larger, the setup on stage is better to integrate in a pedal board.
With the GR-1 harmonics can be changed by foot switching where the red/blue LED indicates the switching mode.
Only the GR-1 can be controlled by the Foot Controller.
