nocaster, i think that a 1 pickup L500XL guitar with q filter can come close to almost having a neck pup sound.
but like fuzzy said no single coil neck pup.

my guitar with the XL alone has the seriel/parralel switch and the q filter with switch


1 master volume 500Kohm and i think a 250Kohm tone.

in serial position the q filter has the most effect and with high gain settings, for me the XL sounds somekind neckpup.

if one likes this maybe another switch is handy to take you from a no tone setting in a already set tone setting, like you where switching from bridge to neck.
(hope you understand what i mean)
