I have an addiction to guitar gear and accessories. There. I said it. The only thing is, that I don't even feel bad! I have worked in music stores forever so I have always got my strings and winders cleaners and whatnot for cheep but, since I have been in school for the last year I have not been able to work at a music store for a while. That means that all of my little music goodies are expensive again! So I decided to take things into my own hands and I started an online store through amazon for all of the little things that I love and use on my instruments, and the best part is, they cost as much as, or less than what I could get them with my employee's discount. Anyway, more than this post being just an advertisement for my online store, maybe its an idea for you to do the same with products that you like.
In my store I start with a huge directory that you can use the search to find what you are looking for, then I have tabs on the side for some of my favourite musical goodies. Feel free to check it out here!
