We have many other signed guitars in stock, but have simply not had time to get them out of storage and photograph them. It should be noted that these are guitars that have been signed by the artist, and not used by the artist! as that would make them far more valuable. In most cases it is the pick guard (scratchplate) that has been signed and then added to the guitar at a later date, as carrying around guitars to get signed is a very difficult job, but carrying half dozen pick guards is much easier!
Please also be aware that there are several websites offering signed guitars and all manner of other music signed items, all of which are fake. If you see all the top names such as Rolling Stones, Who, Clapton etc, on fully signed guitars or drum skins, then allow your common sense to take over and run a mile!
To give you some idea of their true value, a Rolling Stones or Pink Floyd signed guitar would sell for around £2500 up at any good auction, which is why that Rolling Stones signed guitar you have seen at that wonderful website offering every name under the sun for less than £1000 is not authentic!
