I have heard that the AVRI Jag tailpiece assemblies are higher quality than the stock CP units? Are they interchangeable? If so, can I switch the screw in collet for the bar from the CP over to the AVRI? I do prefer the CP screw in unit over the AVRI. Better yet (for me) is the improved pop in unit from the Johnny Marr signature Jag. Could I put the Johnny Marr collet on an AVRI unit and then install it on my CP Jag (I like the trem lock on the AVRI)?
