There's been a lot of joking (possibly with truth behind it) on this thread, about "you'll want more PRS guitars".
Don't get me wrong, I love mine so far. But I don't understand why people would want lots of them. Why split your money into several excellent guitars, when you can pool it all into one heaven-sent one. Even if you can afford multiple exotic PRS, you must still have a favourite. So would there be an occasion where you'd choose to play one that isn't your favourite? Or for the price of a collection of 6 core PRS, I could get something truly special and one-of-a-kind.
As mentioned already, I'm just an occasional hobbyist, not a serious player so there could be something I 'just don't get'. But if I were to buy another guitar, surely it'd be something totally different to what I already have?
I have 5 cores myself and everyone is a different instrument. The 594 is a vintage Les Paul type, the 509 is a more a super-strat, the Custom 24 is a modern double humbucker guitar and the archetypical PRS, the Hollowbody ii is a hollowbody (obviously) and offers a Piezo and the Special Semi-Hollow is an incredibly versatile and very different humbucker guitar to all the others I own.
A Strat is very different from a Les Paul. One has a 25.5" scale, trem bridge, 3 Single coils etc and the other is a double humbucker, 24.75" scale, fixed bridge guitar. Split the HB can get a more stratty like SC tone but they are still different sounding. Then you have P90's, Filtertrons etc, active and passive as well as low turn, low output and hot pick-ups, solid, semi-hollow, hollow body guitars, Extended range/baritone guitars, 6, 7 or more strings etc etc. It doesn't matter how much you spend, you cannot get all these sounds (or even most of them) in one guitar.
You can spend 10k+ on a Les Paul type but that won't help if you need a Strat and chasing the Gilmore/Hendrix tone. It won't help if you want/need to do those Tremolo dive bombs, flutters or other tricks these allow that Steve Vai or numerous 80's rock songs have, you aren't going to get the country telecaster sounds or Gretcsh tones from it either. The pick-ups may be great for certain types of music but
I am not saying you yourself needs a wide range of guitars to cover a wide range of tonal options but having a few does give you a greater tonal palette to paint your music with. There is a reason a lot of guitarists have more than 1 guitar because 1 guitar is quite limiting if you want to get certain sounds. I know professionals may need more 1 of the same instrument because they need a back-up in case a string breaks or different tunings as you can't stop mid gig to replace a broken string (unless you are BB King) or retune your guitar but If you want to sound like Gilmore's Comfortably Numb solo one day and then play some Angus Young or Slash solo the next, you need more than 1 guitar.
I am sure you have heard the expression that guitars are tools and having the right tools for job can be important - even for a hobbyist. You may get by with just 1 sharp knife in the kitchen but if you enjoy cooking a lot, you will need more tools than that and even have specialist knives for certain jobs. I am a hobbyist too when it comes to guitar playing and have multiple tools with each having its role in my collection, each providing something I can't get from the other guitars I have.
Even very similar guitars like the Custom 22 and Custom 24, where the only difference seems to be the number of frets, sound different in 4 out of the 5 different pick-up switching because the position of the neck pick-up is different so has a different sound even though the Pick-ups are the same. A silver Sky and a 594 are very different like a Fender Strat and Gibson LP are - both of which are different from the Cu22 and Cu24, different from the HBii and 509 etc. This is why you can have multiple PRS guitars and not have 2 instruments the same. Maybe for you, the differences between some models are not significant enough to warrant purchasing or the style/genres of music you play can be achieved on one guitar but each to their own. The vast array of guitars though offer something unique that adds to the tonal palette a guitarist has to be creative with and its impossible to cover all those in a single instrument...
