Currently on my squier i have 500k pots for tone and volume , how will changing to 250k pots affect the overall tone.
250K pots will warm up the guitar's tone - especially on the tone control (but the volume pot will have an effect too because it will load the pickups more). More like turning the tone pot down to 9 than 5 though (log taper pots remember). If the pickups are single-coil, the 250K will sound better, but if it's humbuckers, it'll turn 'em to mud (IMO).
How will the graphtec nut and string tree change the sound aswell .
If the nut you have now is the standard Squier plastic one, a Graph Tech will make a huge difference to tone, sustain - just general quality of tone.
