Why TonKontrol?
100% Turkish design and software
The hardware and software design of our circuits is ours. An electrical-electronics engineer does the designs.
Every circuit is tested
We handle every stage of production in-house. Every circuit is tested when production is finished and marked with its production date.
Designed together with musicians
We decide on new circuits based on what musicians ask for and suggest, and we meet musicians one-on-one during the design process.
