I have been much more selective in what guitars and amps I buy and have been concentrating on substantially upgrading my collection, instead of buying a lot of less expensive guitars. My latest purchase, an Epiphone LP Custom in black is one of my best playing and sounding and definitely looking guitars. I play it thru a Fender Hot Rod Deluxe mostly. I might get a SuperSonic someday, as one near me is available new for about half price in blonde.
So being more selective and concentrating on upgrading my collection of guitars and amps has helped a lot. I'm finding that with the nicer stuff I'm more satisfied and don't feel the need to get a lot of new stuff except certain things that I'm focusing on.
My latest amp is an Egnater Tweaker head. An outstanding amp thru my cabs.
Another thing I have been doing is upgrading the pickups and electronics in some of my favorite less high quality guitars with things like Seymour Duncan pickups and Fender Custom Shop pickups. These are relatively inexpensive and can make a very big improvement in the sound and looks of your favorite instruments. Plus you learn a lot when you start hot rodding your guitars.
Nice tube amps are definitely nice and having at least one would be very satisfying. The sound is, in my experience, way improved over the solid state amps. My Hot Rod Deluxe and LP Custom combination produces a sound that blooms when you strike a note, and it has very satisfying natural breakup on the clean channel. Amps like that require a concentrated selection process and a consideral sum, but the payoff is very rewarding when you get something good, within your means.
I also buy a lot of other things besides guitars, that I have been wanting. Like a 46 inch Sony TV and a PS3 and games, power and hand tools.
