During my career I have always tried to improve and modify products.
The Dual drive was the first product that I single-handedly brought to the market.
In the mean time there have been many modifications including distortion characteristics and switching. It is even possible to cascade several Dual Drives and to modify the switching so that only one channel is active.
As well as the Dual Drive two boosters and a reverb unit in the form of a pedal are available.
There are more products in the pipeline.
