j'ai trouvé un p'tit topo sur Hamer pas Ed Roman
Citation:
Check out the control cavity in any USA Hamer, for instance. Remove the conductive aluminum back plate from the guitar and take a look. Notice how the cavity is flawless, almost beautiful in appearance? It's extremely functional, too, and carefully coated with a premium nickel based paint against noise. All of the rugged, top shelf electronics it houses are totally RF shielded, as well.
Speaking of electronics, the volume pots are custom tapered with a boost at the last 1/10th of rotation for easy volume gain into solo breaks. Naturally, all of Hamer's pots, jacks and switches are of the finest American quality available.
Hamer carefully matches pickup specifications, among other things, to the timbre of the guitar's body and neck. To insure versatility and quality of tone, Hamer never specifies identical pickups for neck and bridge positions - a common mistake with other brands. Even the way the pickups are attached is unique. On many models, threaded brass inserts are used for stability rather than just flimsy wood screws. All of the screws are hardened for strength and coated to prevent rust.
Each and every Hamer fret is hand seated, The Hamer craftsman must feel how the fret enters the wood a machine simply cannot do it properly. I was at the USA made Ibanez factory several years ago and they were all proudly showing me a new contraption they had developed to install all of the frets at once in a neck. Those American made Ibanez guitars failed miserably. I don't much like their Japanese ones anymore either. Let them sell their guitars back in Tokyo.
Hamer Fingerboards are carefully quarter sawn for long life, perpetual straightness and ease of neck adjustment. I saw piles of rejected fingerboards due to them not meeting criteria. As I stated earlier in this article Hamer rejects a lot of wood, The Fingerboards are the most carefully inspected in the industry and have the highest rejection factor. You can be sure that no matter what model Hamer you own, The Fingerboard will be a super high quality premium piece of Rosewood or Ebony.
Hamer's exclusive "stressed neck" system consists of three piece necks with opposing wood grains to insure straight and true lifetime performance. Low mass truss rods are easily accessible at the headstock.
Each set-in guitar neck is joined to its body with a specially designed, radically oversized dovetail joint that enhances the transmission of energy throughout the instrument and strengthens the guitar structurally. And, Hamer was the first company to create chopped neck joints and angled neck heels for their bolt-on neck guitars.
The beauty of Hamer Guitars is the result of the expert application of 14 coats of the highest grade lacquers and time consuming hand buffing.
