Those friends maintain the huge and unique work:
Heinz Fässler worked with Rolf on the later Avalons 1993-1995
here he is creating the picks at Frankfurt Messe around 2000. he does all kinds of mechanical works and loves learning and inventing. recently his main focus is on creating personalized card games mainly for the swiss game Jassen
after Rolf died he was the fundamental support to mount the guitar parts that were left and repair the machines to be sold and come up with incredible ideas, sometimes fun sometimes totally practical. he even designed the Muurmeli for Ursetta and solved many other graphical problems – and he helped to keep the good humor in dificult times!
the only FireWire guitar was created.
Concept: Matthias Grob, Rolf Spuler
Hardware: Philipp Scheidegger
Software: Day Koch
Plug-ins: Matthias Grob, Andy Butler
Support: BridgeCo, Axon
around 2017 he created the layout and the preamp of the Polybass and increased battery life with his experience and love for details and improvement.
Matthias Grob started building his special guitar amp with hexaphonic distortion in Zürich around 1978
they met because Rolf was interested in the hexaphonic technology in 1982
the picture shows Rolf and Matthias at the Frankfurt Musik Messe 1993 the only time the LOOP delay was shown (Gibson did not show the Echoplex).
he builds his own guitars and hacks and connects Macintoshes. he is the only one I am aware of who takes new gear apart and builds the main PCB into his ultra compact “guitar amp” and feeds it from a central supply – so he can take all on the train easily because he rejects cars…
and he gave the idea for the wooDI “effect” !
he also builds the most complex live looping tools of the world customized in max and controls them with pedals built from keyboard electronics…
Ljubo does not care for success. He never published recordings of his music. He played at some guitar festivals, but recently complained that its not worth the effort. Yet, all guitar players that have seen him play agree that he is one of the most remarkable musicians of our time…
we reject endorser business. musicians play our instruments because they love them:
