We could never put a piece of plastic on these, not even transparent acrylic !

Modern Electronics
Every M-Series comes equiped with our Modern Electronics Configuration.
Contrary to what the name might evoke, the Modern Configuration is modern by its power, versatility and potential, rather than being specifically meant for modern genres like prog or fusion. But it does it like nothing else !
This Configuration features active electronics, more complex layouts for advanced tonescaping, and our AURA III Pickups Family. These are noisecancelling pickups with modern components and advanced architectures.
