The 6 prototypes |
In 1994 the first Double Trolley prototype was made.
For the next 5 years, the Double Trolley was tested by him and many other bass players to find out how to improve every detail of the concept.
In 1999 the last prototype was finished. The Double Trolley had undergone several changes and was now ready to go into production. Have a look at the history of the prototypes: |

I recently purchase one of your trolleys, and I must say congratulations.
It is well designed and built, and very comfortable. I have used it for a number of rehearsals and concerts,
and have never failed to get envious comments from my section mates.
Thanks again for a very intelligently designed product.
