Gretsch did not build all of its own amplifiers: a large part of the 1960s line, including the 61xx models, came from Valco, and those amps are dated with the Valco table. The first step is always the nameplate, because a metal plate up to 1964 and a foil sticker from 1964 carry different numbering systems.
Gretsch amps were named by four-digit model numbers, with the 61xx series covering the Valco-built combos. A small metal plate on two brass nails carries the number, and the Valco table dates it.
From 1964 the plate gave way to a rectangular foil sticker with a numeric prefix: 1 for 1964–68 and 2 for 1968. Foil stickers peel off, which leaves component codes as the only route.
The later amps use 71xx model numbers — Nashville, Tornado and Rogue among them — which the reference listing places in 1968–1970.
Gretsch-branded reissues appear in the 2000s as separate products, with construction of their own and nothing in common with the Valco numbering.
| Series | Years | Rows | Era note |
|---|---|---|---|
| Valco metal number plate 1940-1964 (Gretsch amps built by Valco) | 1940–1964 | 22 | |
| Post-1964 foil sticker: prefix 1 (1964-68) / 2 (1968) | 1964–1968 | 2 |

A prefix of 1 covers 1964–68 and a prefix of 2 marks 1968.
No, and the canon data warns specifically against decoding it as one.
Then the amp cannot be dated by its own numbering and has to be dated from EIA component codes and the model era.
