I came to play the electric guitar as a teenager in the 1970s and, due to a lack of financial resources, I first autodicactically acquired the knowledge that enabled me to create all the associated electronic equipment myself.

German TV programs like Jean Pütz "Introduction to Electronics", but also my local book hall in Hamburg offered me enough food.

Also I often opened the tube amps used by my buddies from that era and laboriously drew the circuit diagram.

It showed me the astonishingly small differences between Marshall, Fender and Orange amps very early on!

So I built an VOX AC30 Top Boost clone as my 1st tube amp at the end of the 70s, which I then kept tweaking.

My amps have accompanied me on stages in Germany for years (see the young guy below ;-)).

From today's perspective, it is interesting what I developed back then and which is now patented by American amp manufacturers.

For other musicians, for example, later I built some Mesa Boogies MK2 during my studies, but also developed semi-professional vocal systems, mixers and customer-specific amps with a friend and fellow musician.

These early experiences sparked my interest in electrical engineering and in later studies.

After obtaining my graduation diploma in electronics, my goal was to develop guitar amplifiers and music electronics.

The reality and the prospect of higher earnings, however, brought me straight into the industry as a hardware and software developer.

Meanwhile for many years now, I have been working in the semiconductor industry for a large well-known American company and no longer develop myself.

Especially the ODvS-D50 project is my outlet, so to speak, to combine work and hobby with a portion of creativity.

Re-entry into the world of tubes was about 10 years ago on the occasion of the 18th birthday of my son (guitarist of a now well-known metal band), for whom I built a special version of the Peavey 6550 Metal Amp.

Enthusiasm for tube technology and decades of experience in electronics and at the same time an ambitious guitarist life in semi-professional bands were the initial spark for the ODvS50 project.

Due to my professional activities, I am pretty good at conveying complex relationships in an easy-to-understand way.

So I plan workshops to give interested guitarists who would like to build guitar amps themselves the necessary knowledge in a playful way.

Stay tuned and contact me in case!
