Switch in/out the third gain stage

[crocket]

I want to be able to have just the 2 gain stages for bold cleans

Can someone help me with a schematic to switch in or out the third gain stage.

I love the express tone I just want to chug out big clean chords aswell
Like a blonde bassman I made once.

Thank you
Davey

The 3rd stage in the Express only clips after turning the volume up past the point of output-tube distortion, and beyond the point of PI-tube distortion. So switching it out won't create more headroom regarding audible volume. It will create more headroom on the volume knob's position but that is just a knob setting and only matters if you play for Spinal Tap.

For more clean volume potential you need to get the output tubes to clip later.

I think the tone of 3 gain stages is different to 2 regardless of voltage division via a pot.
