We always recommend JJ valves for this amplifier. This is because they guarantee you get awesome tone and long life and they don’t cost a fortune.

Remember, JJ is one of only five manufacturers in the world. So don’t pay higher prices for valves from the same factory that have simply been rebranded by other companies.

What Two Rock say about this amp

“Our best selling series, universally praised for its extraordinary clean headroom, dynamics, and a variety of tone shaping options.

Best described as a “portable” Classic Reverb/Custom Clean hybrid, it includes an added pick up loading feature that optimizes balance between single coil and humbuckers.

A stellar reverb circuit with Send and Return controls, contour control and full buffered effects loop is standard on this amp.”

About the amp bias settings:

• Fixed bias (meaning the bias can be adjusted to a fixed setting).
• 6V6 power tubes installed in the 22 watt versions only: .044V to .058V
• 6V6 power tubes installed in 22 watt versions with tremolo. NOTE: bias must not be set higher then .044V as it will cause tube failure.
