Have any ideas to change the pickup or the caps value??
Hi mayfair, an interesting question which I'm also testing at the moment with four different Tokai Love Rocks. I just found the original "Tokai '57 PAF model" pickups in my cellar again that my first LS 60 from 1984 came with. When measuring the impedance they both show a quite high value of 8.28 and 8.24 kOhms. While this can be OK for a bridge pickup, it's too high for the neck position where you would rather expect something around 7.0-7.5 kOhms. The original Gibsons also had rather similar values, by the way, so using a neck pickup with a lower value is a "modern" idea, but a good one actually, because it sounds too dark and muddy when having the same value as the bridge pickup.
I also have a single DiMarzio PAF from ~1979 in another guitar (Ibanez Musician) which sounds very good in the neck position. Maybe I'll swap it to one of my Tokai Love Rocks in the next days. The LS 60 has two Gibson Shaw PAFs from 1983 which sound very good, and the LS 120 has two Gibson P-94 single coils in humbucker size which fit to its dark rich sound quite well.
Before you start changing pickups, it's important to know how your guitars sound without an amp, because you can only change nuances with pickups and cannot get something back which wasn't there in the first place and/or get rid of something that will always be there.
The "cap value" doesn't change the sound if you turn the tone control to 10, only if you actually use its function and turn it down. It might be possible that you don't have 500k volume pots (maybe 300k) which would lose some treble, too, but again only in very small detail, nothing more.
