History of GregoryPreAmps


GregoryPreAmps is the result of two passion: to music and electronics.


Hello, my name is Grzegorz Sebastian Kościk and I’m the constructor and creator of GregoryPreAmps. In the early 1990s I started playing the guitar and got interested in electronics. Later education allowed me to expand my knowledge and develop it in audio electronics direction. Ability to play the guitar and bass let me take a proper course in designing and building preamps.

In 2006, I built a prototype of the M-BP3 bass preamplifier exclusively for the local company Mayones, which produces guitars and basses. Good quality and reliability resulted in long-term cooperation. The preamp has gained the appreciation of many famous musicians. In 2020, we ended our cooperation. We are currently focusing on building our own brand and developing new projects from the G-BP3 series.

In my constructions I use selected semiconductor components with low noise and foil capacitors in audio track. Whole production process takes place in GregoryPreAmps, from electronics parts montage, wiring, testing to hermetic protection with special epoxy filler. It allows on full quality control on all production stages.

Our goal is the highest sound quality. At the moment we are having the latest 3rd generation preamps.
