Hey guys! Obviously, reading the thread title, I have questions about guitars that have more strings than the one I possess (why dont I have a 7 string yet? ) I must say that even wanting to be a luthier, I dont own all of the knowledge related to guitars (thus making you guys a highly relevant source of info ) First of, with that lovelly piece of equipement being the bridge: I plan on buying a Hipshot guitar bridge, fixed, black for the modest sum of 109$ +taxes, shipping and handleling. Here Scrolling down you might see that there is 2 black 7 string fixed guitar bridges, one having the .125 mention and the other one having the .175. - Whats the difference, if you could answer, is it overall width, thickness of the baseplate, something else? Now, moving on to the tuning machines: Hipshot also sell those (yeah!!) but after making carefull mathematical equations I noticed that the "black grip-lock locking guitar tuning machines" that I was looking into cost 15$ each, giving a big 105$ for 7 tuning thingys. So, two questions in one: - Are they good at what they were made for and is there any cheaper way of having locking tuners (are Sperzels cheaper)? Finally, frets, those magical little pieces of metal, I have found after carefull reading of that thing called the Internet that the biggest frets ever made were the Dunlop 6000. - Where does one find those frets? Also, could you guide me in my quest for supreme speed, because I dont know if those Dunlop frets are big because of there height or there width or both. My interrogation is mainly caused by the fact that there is Stewmac frets that are more pyramidal shaped compared to the rounder common shaped frets here you can see the last 2 frets size have 2 differents "slopes". Also, how do they compare with the aforementionned Dunlops? And now, regarding neck width, whats the typicall neck width on a 7 string at the 24th fret? I know that the nut is 48mm (I dont how much that gives in english system though ) Thanks for reading guys.
