2010's rock the house. 50s wiring, CTS 500k audio-taper potentiometer for volume and tone. All this equals a smooth, natural roll-off. No need to change anything electronic unless you do not like the pickups or you are really, really picky.
Here is a list of the changes
2009 R9 Changed Features:
Nylon 6/6 nut
Improved ABR-1 bridge (no-wire, tighter tolerances)
Historically correct nickel-plated brass bridge saddles
Correct alloy saddle adjustment screws
Bridge height-adjusting thumbwheels are now thinner
Neck profile changed - now has less "shoulders"
Audio taper CTS pots
50s wiring
Pickup routes adjusted so that pickups will be parallel to the strings
Top carve changed to be closer to several original '59s that were scanned
Body perimeter change - slightly tighter in waist, cutaway area refined to be more like originals
The maple cap is very slightly thinner, the mahogany body is very slightly thicker
The fingerboard is slightly thinner
The step from neck heel to back of body is taller and more correct
The taper of the "maple window" under the binding in cutaway is more accurate
The maple spline (filler strip) in the tenon is more accurate
The edge radius on the backside of the body is tighter (less rounded)
The "mustache curve" of the headstock top has been flattened slightly
The control cavity plate has been relocated, has the correct side taper, and now uses the correct ABS plastic
The pickguard shape has changed slightly
The pickguard bracket and screw have been changed
The truss rod cover has been reshaped to be more accurate
The serial number location is slightly lower and more correct
Dial pointers are less sharp
The strap button screws are longer
The jack hole is now the correct 1" diameter
The toggle switch nut has more correct knurled pattern
thanks.
But the caps could use a swamp, no?
A true blind test here...
Which color was the real BBs?
To my ears, pink caps were better.
What settings were on the tone controls out of curiosity?
