It depends on the instrument. There are a few sig basses that I would have loved but the name placement or design stopped that.
The Spector Ian Hill and Fender Sting both have that monstrous 12th fret inlay, and one of Fender's Steve Harris Precisions had the West Ham logo on the body. That's just asking for trouble on certain pub gigs! Why it wasn't a removable decal like on the Roger Waters bass is beyond me.
Green Day's Mike Dirnt had the right idea - he made sure his signature wasn't visible on the front so the Green Day connection didn't serve as a deterrent.
Doesn't look like the DE signature as they had mirror scratchplates, but you'll easily know for sure by the signature on the headstock.
Even if it's not a DE these are excellent basses, £99 is a bargain.
