went down to SL to try the Lps out! Well from the tryout, actually really cant feel "the" big of a difference in the both necks, but the 50s neck did add alot of presence and fullness in the tone! dunno weather if was in the pups, but the difference in sound definately there!
60s neck, sounded rather thin and weak, den again could hv been the pups, overall frm the tryout today, i think my money is on the 50s neck!
Although, wen i put both LPs side by side, there was a little visual difference .... well very slight though!
