Dating fender vibro champ
An updated version was introduced in 2006 as part of the "Vintage Modified" line.
The Champ had the lowest power output and the simplest circuit for all of the Fender tube amps.
The Champ had only one power tube,and the power stage circuit is, typically, single-ended and class A.
A small number of the last 5F1 style cabinets were covered with the "Blackface" amp cosmetics around this transition, as the factory most likely ran out of the tweed cloth covering. Fender brought back the blackface cosmetics for a short time in 1981 before discontinuing the Champ the following year. Cosmetically similar to the original Champion 600, internally it features a modified blackface Champ circuit (with the settings of the tone stack being hard-wired rather than adjustable via Treble and Bass controls, and a couple of additional resistors reducing input-stage gain) and a switch to solid-state rectification from the original 5Y3 tube.
The current look is the TV-front with two-tone tolex and speaker grille cloth of imitation suede.
For a time after Fender's takeover of Gretsch, the same electronics were available with a different look and feel – based on "tweed" Fender amps, despite the branding – as the Gretsch G5222 Electromatic.
Production of the Champion 600 reissue ceased in 2010 and was reintroduced by Fender in late 2014.
As of 2016, the Champion 600 was once again discontinued.
The Fender Vibro Champ was a guitar amplifier made by Fender.
