I checked out a couple of sites on this new type of pup and the ones I found were for bass only, is this true?
From what I found they're described as reproducing the natural sound of strings/wood etc with no colouring of the tone whatsoever.
While this may be acceptable for bassists it may not be so good for guitarists.
Maybe that's why I couldn't find any for guitars?
We use different pups on our axes in order to achieve a particular tone that we want, Vintage,JB, distortion, single coils,humbuckers etc etc
Another thought is that these optical pups would highlight shortcomings in cheaper instruments so that you could only use them on axes made of quality timber etc whereas conventional replacement pups would help to shroud and/or enhance the crappy tone of a guitar made of inferior timbers.
I guess this applies to basses as well.
A Squire "P" bass can be made to sound a lot more like a MIA Fender "P" bass if you install pups by Seymour Duncan, DiMarzio etc etc .
If you install one of these new optical pups then the Squire "P" bass might sound even less like the real thang, dig?
