2000 - 2011 The acoustic emerge

Crafter   What Jonas preffered to play beginning of 2000 was an inexpensive acoustic model of Crafter. This instrument was heavily modified with custom pickups and electronics. It is featured on the Paris DVD, recorded live from a concert with Shawn Lane and the Vinayakram brothers at New Morning in Paris.   An extra version of the instrument was a black 5 string, subsequently modified into a 6 string.

Warwick

In 2004 Hellborg walked into the Warwick booth at the Frankfurt Musik Messe and a deep involvement in instrument design and friendship with Warwick owner Hans Peter Wilfer started.
The first step was Hellborg’s fascination with the acoustic Alien bass guitar. This led to the development of Jonas “dream” Electric Bass, an acoustic size and shaped body with a ultralow impedance pickup that gives a dramatic dynamic range and flat frequency response from 20 Hz to 20 kHz.
Jonas later got involved with the electronics department and started out with developing his own high end series of amplifiers and speaker cabinets.
