I age chrome and nickel parts myself, but I wanted to compare my results with that of a Japanese company that manufactures guitar and bass parts of good quality. Unfortunately, the item received is... simply not aged. It has nothing to do with the one depicted on Thomann webpage, and only after a careful observation, one could notice that is not brand new. That was disappointing. On the other hand, I'm now quite satisfied with the results achieved with my aging technique.
