If you don't play them, then why own them? To collect??? No offense intended but, what a waste of a great guitar. I invest so much time into my guitar (DNA) that I expect something back from it. Should it sit there and gather dust, would defeat the intentions of the instrument. It doesn't allow its character to develop.
...going to get a little "touchy-feely" now...
Entertain this perspective for a moment.
If any of you (as I am sure most have) really play, then you must understand the symbiotic relationship that forms between the guitar (or whatever instrument) and the musician.
The wood has certain energies just as we, people, have energies (auras). The more we put into the instrument the more it learns to interpret our style, phrasings, interpretations, etc. Eventually, that union is formed and become an omnipresence, or inherent, primary quality of the guitar. Surely at some point any of you may have picked up an instrument that you might normally consider to be of lesser quality? You then play it and it is magical; it actually speaks to the core of your existence. That voice is the energies of people who developed that special, symbiotic relationship with their instrument.
To allow a beautiful instrument to just exist without stimuli parallels the notion of having a child and then avoiding any type of commitments to or developments of that child.
It may sound like a load of sh*t. However, those of you out there that know the experience just know. It is the segue to separation.
I hope that doesn't sound too elitist but that is my approach and has been for 15 of my 20 years playing. If any of you know Steve, you should talk to him about it. It's called the vine of life for a reason.
