This from Glendales web page: "Magnetic 1950's: The Glendale magnetic bridge-plate will enhanced your guitar's sound. It will become vibrant with more over tones, more definition, more acoustic, and better frequency response. Bringing out the best of the 1950's Tele sound. If you want to enhanced your guitars tone with the 1950's sound this is the bridge-plate for you. I recommend you use Alnico 3 pickups to get the 50's tone. Non-Magnetic 1960's: The non-magnetic is very percussive, rich and alive sounding with great Twang, really enhancing the 1960's Tele sound that I set out to achieve. In Redd Volkaert's words "I ordered the new non-magnetic bridge, and my Tele came to life, more overtones & harmonics." If you want a very balanced tone and lots of twang, this is the bridge for you. I also use the Non-Magnetic bridge-plate. I recommend you use Alnico 5 pickups to get the 60's tone. Non-Magnetic verses Magnetic: The early 1950's Teles do not have the twang of the 1960's Teles. The non-magnetic bridge-plate helps bring out the twang of the 60's. Leo used steel saddles in the 60's witch have more twang than brass. In my opinion you can use brass saddles and a non-magnetic bridge-plate and get the best twang and the great tone of brass." Is a magnetic bridge plate really going to have such an effect on the tone of the guitar, or is it more about the vibrations being carried through from the strings to the guitar body, being influenced differently by different metals (eg: brass saddles)? Does it have anything to do with the mysterious powers of magnetism?
