Soundwise the newer Dunlop's with fasel sound just as good as the Vox, but their buffer's suck tone and they aren't TB (but since you're modding yours that shouldn't bother you).
Basically, if you're going to mod your own I wouldn't waist yor money on a Vox; and if you're going to swap the inductor, don't waste your money on a Dunlop w/ Fasel inductor.
