The ValveTrain 635
Buy Me Now

The ValveTrain 635 (which replaced the ValveTrain 535) is our take on the mid-power amps from the late 50’s. Powered by a duet of Vintage Style 5881 tubes running in fixed bias, this amp produces a wide spectrum of harmonically rich clean tones that are great for jazz and traditional country. Crank it up for a walk down memory lane to vintage rock & roll.

We have added oversize transformers and own custom selected 10″ Alnico magnet speakers. This all-tube combo amp has hand-wired circuitry, and features for the modern guitarist.

We have activated both channels and allow them to be blended and a Master Volume has been added for further tonal control

Control panel details include normal and bright volumes, two inputs, bass, treble, master volume and presence controls.

The 635’s solid pine cabinet resonates with a warm, woody tone. The amp is covered in our Bedroom Beauty Tweed finish with matching vintage grille cloth. A heavy duty leather strap handle lets you safely transport the 635.
