MC Series Pickups:

The ACG MC Series pickups have come about through lengthy
collaboration between Aaron Armstrong, The MC Series Pickups are the
ultimate pickup to use with the ACG DFM filter pre-amp.. These pickups
are available exclusively on Über Spec basses.

The MC Series Multi-Coil Pickups are part  of a proprietary system
exclusive to AC Guitars. The system uses different components for the
two pickups in order to provide a bridge version and a neck version
which accentuates the tonal qualities for the two positions.

This system leads to improved dynamics and far greater clarity over
the entire range of the bass.

ACG believes that the MC Series pickups offer you the most sonic
versatility and clarity possible, in conjunction with their ACG DFM
preamp every possible subtlety and nuance is present and there to be
played with.

About ART (Acrylic Resin Treated) Woods:

Alan Cringean started using acrylic impregnated woods pretty much
straight away mainly for fingerboards.  Alan could see no down side to
them 20 years ago and this is still very much the case today. The ART
woods came along a bit later and have brought a whole new world of
colours being dyed and dual dyed. Since the process cannot be
controlled where dye takes or does not take produces interesting and
unique tops. The next step was ART/Hybrid tops. These combined ART
boards with epoxy resins. This further increased the complexity of the
colours and textures possible in a top wood.

For 20+ years Alan worked with one guy, Larry Davies on all the ART
and Hybrid tops. They were friends even though they never actually
met. They tried several times but never managed it. Larry Davies sadly
passed away in April 2024. Alan lost a friend and someone that has
been with ACG since the day it started.
