The ValveTrain 427 is an amp that is rich with vintage tone and has an expanded set of controls that will allow today's guitarist access to a tonal palette that was not available with the original amplifiers.

The 427 inherits its' tonal roots from the venerable Fender 5E3 Deluxe from the late 1950's.  Aside from the beefed up power section loaded with a pair of 5881s and the heavy duty transformer set, the most interesting feature of the 427 is the design of the initial gain stages. There are 2 volume controls, one for the Normal channel and one for the Bright channel. The two channels are internally isolated and “jumpered”. This means that the player is able to blend the tonality of each channel into the overall mix. Because the channels are both active, the preamp tube is running in parallel operation producing more gain than is normally found in an amp of this style.

Turning either volume control down, which eliminates that channel, returns the tone of the amp back to the single voice operation of the original. There are also two boost switches that activate a gain and frequency boost on each channel.

By controlling volume and the boost on each channel, the blending of the two distinct voices opens up the tonal spectrum of this amp.
