If not for the SRV profile I'd say an old
Charvel Model 1 series neck would be a great buy. Awesome necks on those old Charvels. Then there is Mighty Mite, Moses graphite (pricey), Stewart McDonald, Allparts, MusiKraft, Edenhaus, and some that are on the tip of my tongue (fingers?) that I just can't think of. There's a Warmoth offshoot, US Parts or something? Someone will pop by in a minute and remember for me
