i think thats the million dollar question, it can be due to a lot of reasons i think, the age of the guitar, the pick ups and probably the wood.

When i hit my second puberty at 50 i went looking for a guitar, must have tried a few dozen some new some not so new, and i always came back to the one i have now which to me sounds better than any of the others i tried, even a brand new fender.

Its nothing fancy but what it is, is a 20+ years old Hohner l59 professional, which i believe was just a run of the mill mass produced guitar back in the 80's,this one is mint condition with all the original bits on it and sound totally sweet.So all i can think to why it sounds better than the others is the age.
