i have plates to sell, with a thick layer of celluloid. I'm using one myself now on my own P bass. Apparently they fit a US and MIM perfectly according to reports from basschat members, and fit a VM pretty well too. See the pictures below that they have kindly taken the time to post.
dark brown early 60s style or later-style mid brown
NB There is a sheet of plastic film on them, but you can see the depth of the top layer.
£16.50 each plus postage at cost (2.95)
I'm happy to use BACS or Paypal, but would appreciate not getting fees
I have a few dark brown Jazz plates with screws, that Norris was kind enough to try on his MIM jazz for me (I don't own one any more) - he said they fitted fine. £18 for those, with screws
Ead advises me that whilst very pretty, they do NOT quite fit the '96 MIK Squier 50th Anniversay Bass as the original is very slightly larger.
I'm happy to send you one on a Fit or Return basis, provided that you send it back in the original state.
thanks
