check out my new trove, it's a 2001 RG520X with Double EDGE system, finished in GK = Galaxy Black. The weird thing is, I simply cannot find it in any catalog, and I have both the European and the US catalogs of 2001 and it's nowhere. However, a German guitar magazine published a review of a RG520XJB in 12/2001, so it must have been available regularly.
The neck is marked "ARG570" on the heel - whatever that means - and the pocket says "RG520X-01" and a date stamp "2001.7.25".
(sorry for the low-fi snapshots)
The features are identical to those of a RG620X with one exception: The L.R. Baggs piezo preamp is configured differently: While the 620 has a 3-way mini switch to select magnetic/mix/piezo, the 520 comes with a 2-way mini switch that selects magnetic/piezo without any mix option - it's also placed in a different spot. And mine has a push/push switch to select the outputs, and the 620 doesn't have it either.
What do you guys think? Is this a limited edition, Germany-only model, spot production model or something like that?
