Many thanks for sharing your opinions and advises! After considering everything you've said, I've decided to 1- put emphasis on improving my barre technique, and if it does not give the desired result, then 2- contact a luthier to work on the saddle in the advised way.
Meanwhile I'd like to ask an additional question on this topic... Can it be so that string gauge has influence on barre playability?
The reason I'm asking is, I switched the strings between the guitar I play and my former guitar (which now mainly "rests"). My former guitar had D'Addario extra high tension strings, while the one I currently play was strung with Savarez normal tension. I did this mainly out of curiousity, wanted to compare what happens if I increase the tension on this guitar (moreover, high tension is for whatever reason advised by my guitar producer).
Naturally, the strings appeared more tense, demanded a little more offort to play and had a fiercer impact on the finger tips, which was of course expected. But for my surprise, I found out that my barre chords sounded significantly clearer with those newly put strings... I am now a little confused, 'cos I think (and you guys also noted this) that the higher the tension, the more effort the playing demands, including playing barre. Thus I came to think there can be only 1 of the 2 reasons:
1 - The high tension strings are thicker. So the hypothesis is, maybe higher string gauge makes it easier to take a clear barre?
2 - It could also be so that my barre technique improved overnight
But I fear this is as realistic as the Tooth Fairy...
Looking forwards to hear your competent opinion, once again
And many thanks!
