Inventor of the Double Trolley, Marc Grue, explains:
"In the beginning, I had to learn how to weld steel tubes to put the prototypes together. Using my first hand knowledge as a bass player, combined with my newly learnt engineering skills, I was able to assess which details needed improvement - for example one screw would hit a narrow door frame, one edge was too sharp when you lifted the bass into the bus, and a lock mechanism needed to be redesigned.
The Double Trolley is the culmination of all of these experiences and improvements." |

The final prototype was drawn from scratch on a computer incorporating the lessons learnt from all of the previous prototypes.
Engineer Henning Forbech from Techvision helped to make proportions and technical details of the whole construction before it went into production. |

We have received the Double Trolley here in Canada and I'm writing to thank you for your wonderful product!
So far it is working perfectly - I tested it out this past weekend on my way to orchestra - you see, I am a member
of the Toronto Symphony Youth Orchestra, but I live far away from Toronto and need to take the train and the subway
to get to and travel about Toronto......thank you for making it that much easier!
