NAD: 1987X - JiveTurkey & La Szum are to blame! 😭

Tip; Here's how I jump the channels on a Plexi.
Guitar into Normal 2 HI.
Jump Normal 2 LO into Treble 1 LO.

It give more useful range for adjusting clean tones from both Treble and Normal channel volumes, since it's using both low Inputs instead of both high inputs.
Add a one knob volume box in the fx loop and enjoy almost Fender like cleans from a Plexi, works amazing with pedals.

I’ll have to give this a try. Thanks for sharing.

Don't be afraid to use Bassman and Plexi controls at their extremes. While things evolved with the Marshall's, the flattest tone stack settings on a Bassman are B and T all the way down and mids all the way up. This is generally where I start with a 4 hole Marshall as well, and then add bass and treble or dial back mids as needed. I may end up far from that starting point, but I find it a helpful way to dial in a new amp.

This is a cool web tool to visualize the curve created by manipulating the tone stack of different tube amps https://www.guitarscience.net/tsc/marshall.htm

Yes, just keep in mind that that is the tone stack only and there is other filtering done with the coupling caps, cathode bypass, NFB/presence etc. so the frequency response of the amp can be quite different than just what the tone stack shows.
