I have An amazing fender custom shop 63 strat nos in red heavy sparkle.
I currently have a ce 24 that’s amazing.
im considering selling the custom shop strat to pick up another prs. I’d like a McCarty 594 or maybe a custom core.
I just don’t know if it’s worth it or if the prs will be too similar to what I already have.
thoughts?
The McCarty models are PRS more vintage/classic instruments inspired by 'Gibson' so unlike the CS Strat or CE24 you have - the Silver Sky is the Closest instrument to your '63' inspired Fender. The 594 is more like a 50's Les Paul - often regarded as the 'opposite' to a Strat.
No one can answer whether you should sell and/or buy whatever instruments (regardless of brand/model) because only you know if you will get what you want, what you prefer, what you think is 'worth' it. If you don't use your CS Strat and its just sat there with your money tied up in it doing 'nothing' for you, then selling it and buying a 'cheap' Squire that basically does the 'same' thing but you actually play it more is worth doing. If you sell a guitar to buy one you use 'less' or doesn't work for you as well as the guitar you are selling, its never worth it and you'll probably end up with 'the one that got away' story until you find 'something' that fills that gap.
Based on what you have - a CS Strat and Ce24 - a McCarty 594 is going to be a different vibe and perhaps 'compliment' the CS Strat. After all, a 'Les Paul' and Strat are often considered as 'essential' tones in Guitar music history and the 594 is a 'vintage' LP inspired instrument so would add to your tonal palette. The Ce24 is a very different instrument and the 24fret neck changes the position of the 'neck' HB relative to the bridge so will sound quite different to a similar scaled 22 fret guitar.
The only way you'll know if a Guitar is 'worth it' to you is by trying them and as we all have different preferences, different needs, different hearing etc, the ONLY one who'll know if its 'worth it' for you is you...
All I can do is tell you that a 594 is different to both your guitars so if you 'lose' your Strat and what it offers, the 594 is not going to replace that or step on the toes of your Ce24 but whether its worth it or not depends on whether you'd prefer a more 'Les Paul' inspired instrument or not...
