The "Bright" channel's (the originals never called it Bright, it was Mic and Instrument) High input should provide plenty of top end.
As you push up the Tone control you do add more gain to the amp, and eventually at higher settings it will almost seem to smash the treble down when it all starts naturally compressing.
While the Volume controls are interactive, having one off or low will not result in the sound you're describing.
How much use has that old 12AY7 seen?

The amp is set for 8 ohm's, and the Speaker is 100 Watts 8 ohm's.
I played with the controls for about 30 mins, but the only way I could get it bright was with the Bridge pickup.
The 12AY7 was part of the tube set given to me by Jim. I am not sure of its age or use, but he said they where all good. I had a choice between JJ's and the US NOS mix when I bough the chassis.
As for the speaker cord, its a regular 1/4" Instrument cable male, wired with 16 gauge lamp cord.
