CATHODE SELECT SWITCH:
This three-position switch allows you to configure the input tube bass response to match the original circuit of the selected module. This will affect the feel and tightness. Each amp designer has a specific combination of components that make up their input tube circuit. We have selected the three most popular combinations which you can access with this switch. You can experiment and try any of the positions to see what you prefer.
