DEMTON - FUZZ
"Distortion from 1976 . It was a smooth overdriven amplifier with 3 trannies, +diodes cut. It is interesting that 3 coils (multiple output transformers) RLC filter element ensured the special sound character."

DEMTON - multi effects pedal
"In 1975, 1 year later, 50 years ago, I built myself a multi-effects pedal, I think it might have been the first multi-effects in the country. I had never seen anything like it before.
The entire mechanism was also self-made.
Its special feature was that the Wah and Volume pedals were already optoelectronic, not potentiometers. Noiseless and squeak-free.
It had WAH, Phase shifter, compressor and distortion. The sequence of WAH and distortion could be changed with a switch. And the distortion was adjusted with 6 selectable sound volt switches and coiled inductive filters. I loved it very much."
"I think Hungary's first multi-effects pedal was completed in 1977 :-) I outgrew the old simple distortion and wanted to imitate the professional sounds. The little devil was moving in my brain and didn't leave me alone until I created this pedal. This was the content of WAH - Phase shifter - Fuzz - Compressor . The Fuzz and WAH order could be switched with a switch. It was particularly interesting that even then the Volume and WAH were made with optical control without a potentiometer! The Phase Shifter was a copy of a Roland Phaser, I cringed the most because the phase shifting was done by 6 RC members, which were controlled by 6 FETs at the same time. After construction, it sounded pretty bad. In my frustration, I messed around until I realized that the FETs must be exactly the same. Luckily for me, the local parts store had approx. It has 150 FETs, from which I was able to select the 6 identical ones. The result spoke for itself. And I began to learn the profession more and more. Thanks to a bit of luck, it came back to me."
