ABM make some of the finest quality guitarparts whch are individually made on CNC machines from either Bell Brass or Aluminium, they are then hand polished and carefully plated and all in Germany and as such represent very good value when taking into account the time, care and attention that goes into making each piece.
ABM are not that well known but are used by the top guitar builders and Luthiers who are looking for superior components and you will find that the bridges will open up the tone of your guitar and give you more sustain and ringing notes with improved bloom and decay.
