Mike I'm surely speaking as what's right for me. Just sharing my view and sure not to "compare" with others. We all have our ways.
A guitar that has a lot of sentimental value to me is my first electric. Should I have gotten rid of it I'd feel bad and wish I had it.
As it is I got creative many years ago and had nothing going for me other than ambition so
a few weeks ago I decided to try and get it in playing condition- best I can.
Not only to get it playing because really I enjoy having it in the horrible condition it is in because it sure paints many pictures to me lol but
because it is a great opportunity to learn some new things. If I blow it, it will just be another picture of the story.
(I decided to wait until I finished the project and post however it works out.)
At any rate I can sure understand missing an instrument. Maybe my understanding and justification/reasons may be different but it's something we all can relate to in our own way.
I find "why" one misses their guitar or playing gear interesting.
