There is nothing wrong with having only a cheap guitar…or an expensive one…or a really collectible very expensive one…there is nothing wrong with having beginner guitar or a pro quality one…or having only ONE guitar or a massive COLLECTION…and the same with amps as well…
But there is a problem if you spend more time with hunting for a “better” or just a “different” or just an “other” guitar than actually playing on the guitar that you had already purchased because you fell in love with it!
Enjoy what you buy, play on it, play MORE on it and the most important is to play MUSIC! That’s this whole thing about. Play MUSIC! Make your own music with the instrument you fell in love with! Most of the biggest hits of all time were composed on just a very average instrument. Most of them were recorded with just a “normal” instrument…like a Standard Strat or a Les Paul Standard…most of the greatest songs were recorded and composed on NEW or only a few years old instruments…play MUSIC and spend more time with the instrument(s) you already love than searching for more gear!
(It’s a kinda own-goal advice from a guitar dealer but hey at least you can take my words seriously)
