The non-appearance of yon Variety on the Gretsch site is indeed a mystery. Perhaps it's so good an amp it's just not safe to put in the hands of just anyone who can happen to afford it, and they intend to make it a grail quest for the truly deserving.
Maybe general availability would decimate demand for all other boutique amps (not to mention any Fender offerings over, say, 1,500.00), and a secret cabal of boutique makers, secretly chaired by Victoria itself, has conspired to effectively keep the amp off the market by limiting production and infiltrating FMIC with moles who sabotage all attempts to produce print materials or web references to the amps.
Maybe general availability would lead to popularity straining Victoria's production capacity, embarrassing management and forcing ruinous expansion on the company.
Maybe government has intervened and put the kibbosh on wider availability because our mines, forests, and other sources of raw materials can't sustain the level of demand the amp's popularity would create. Nor could governmental budgets bear the pressure of unemployment payments to employees of amp companies failing left and right – not to mention the strain on landfills as other amps are discarded.
I don't know that it's the "best" amp I've ever played – there's at least a generous handfull of amps so good there's really nothing better, just different, and it's a matter for taste to choose among them.
But I've sure never played through anything BETTER.
senojdan, the Variety is rated higher than the Exec, and is physically a bit larger (both are larger than most amps of similar ratings), but it doesn't feel or respond as a notably more powerful amp. Maybe more headroom and available low end.
