Why is the Gain Knob Not Working?

The Gain Knob is directly tied to the Gain Staging and the Gain Staging takes precedence over the Gain Knob. Meaning if the Gain Staging is set to 50% the Gain Knob will not work for any settings below 50%. This is the same in the 100% setting, if the Gain Stage is set to 100% the Gain Knob will not reduce the Gain at all.

If manual adjustment is desired make sure to set the Gain Staging to its lowest setting 25% (White indicating LED).

Why Does the Mid Boost Add So Much Volume?

The Mid Boost is designed to jump you straight into lead territory no matter which Gain Stage you are in. Meaning the lowest Gain Stage (25%) will add the most volume boost and the highest Gain Stage (100%) will add the least volume boost.

What Power Supply Should I Use?

Any standard 9V negative tip power supply will work with MR JAX, just make sure your power supply / power supply port is rated for 100mA or larger.
