In 2001 Mark met Grzegorz Skawiński, a top guitar player in Poland. Grzegorz asked Mark to build a MIDI-based guitar system for him; this system was the original FC-21 MIDI Controller coupled with the PR-16 patch bay. Ever since that day, Mark L Custom and Grzegorz Skawiński continued their musical partnership to keep improving and expanding upon the capabilities and features of that first rig to help push both MLC, and the music, to new boundaries.
At first, MLC designed and built only MIDI controllers, patch bays and universal power supplies. Then, in 2007 he met Paweł Paszkiewicz, a dentist and musician, and Tomek Gacek, a industrial design artist who was also a guitar aficionado. They talked Mark into designing a custom, pre-production tube amp. The task was not an easy one, as it had to combine the quality that MLC was known for with functionalism, aesthetic design, and most importantly TONE. After numerous tests and tweaks, combined with a innovative and stylish case designed by Tomek Gacek, Mark finished his first SUBZERO 60 amp which now stands proudly in Grzegorz Skawiński’s studio; this amp can be heard live on his new “Me and My Guitar” album.
By 2012, the next evolution to the SUBZERO family of amplifiers had been made, namely the SUBZERO 60MKII, SUBZERO 100MKII, as well as the SUBZERO 60MKII STEREO. Additionally, Mark teamed up with Tomek and created a pre-amp and power amplifier for a 19” rack based on the SUBZERO design as a special order for RIVERSIDE’S Piotr Grudziński. This special combo was called the X-RAY, and is mounted in Peter’s rig and ready to rock for the upcoming New Generation Tour.
