Tag Alias: guitar_pick -> plectrum

Aliasing guitar_pick -> plectrum.

Reason: They seem to be the same thing.

Sounds good. 'Plectrum' is also a common English appellation for the various things used to pick Japanese stringed instruments, but I don't think there's any need for a distinction there.

Done

The alias of this seems somewhat counter to what was thought in forum #20405 though. Not that non-guitar plectrum seem to have been tagged with plectrum though.

forum #20405 was mixed, all that changed is that I no longer think it really matters.
