About Us

Duesenberg - a history of Dieter Goelsdorf from 1978 to 2004

1978 The right product at the right time! Amazing success with the »Rockinger Guitars«, the world's first electric guitar kits, plus a range of replacement parts at sensible prices.

1980 Input from new partners and friends, especially from Mathias Jabs (Scorpions, Hannover) led to the development of the first fine-tuning tremolo in the world, the ROCKINGER TRU TUNE TREMOLO. Introduced shortly afterwards by Kramer Guitars onto the US market as "THE EDDIE VAN HALEN TREMOLO".

1981 Set up own US distribution company - ROCKINGER-USA - in Asbury Park, New Jersey. Provocative ads in GP (Guitar Player magazine) lead to worldwide furor. More tremolos follow, like the "TELLYBRATOR" and the "LESTREM".
Not forgetting: P-90 - the all-time favorite pickup! Established a large collection of old American P-90 guitars, which were minutely analyzed. Set up own production of P-90 pickups in authentic design and also special "humbucker" dimensions to fit in standard humbucker rings!

1982 First real celluloid mint green pick guard reproductions, export of tremolos, pickups and pick guards even to South Africa and New Zealand.

1983 Full scale production of guitar bodies and necks including paintshop. Workforce grows to 16 people at Rockinger.

1986 Introduction of the first Duesenberg name guitar with very futuristic designs. Guitar magazine columns under the "Atze Rockinger" byline.

1987 Established FORMENTERA GUITARS. Build your own guitar under the Balearic sun!

1991 Crash Bang! Internal differences lead to sale of Formentera shares and change of ownership at Rockinger

1991 Formation of g ö l d o - no more direct customer contacts. Company focuses on wholesale, production and import. Distribution and export of own and outsourced components to dealers and guitar manufacturers.
