Just started using this amp and its tone stack section is total black face era specs and sound. Has anyone here heard of how to pre amp out this baby before it hits the amp section? They made the bandmaster and the deluxe VM aka vintage modified. Tube preamp/tonestack,etc,solid state amplification. Have searched the forum and I'm just looking where I can intercept on the board and install a preamp out jack. I can't even find a schem on these. I want this to go straight to my mc2100.
Anyhelp would be greatly appreciated,

So the send on the fx loop is like a preamp tap? I can't find any info on this beauty. I didn't know if the circuit is post tone stack or taps into the guitar input line before the tone knobs and tubes and or if it becomes active only if there is a return plugged in.
Thanks will test.

Thanks man!!!!!
Holy this baby is alot harder to trace than my good ol fender twin reverb. I need some gurus help if you have time. All the layers I think I'm going blind. This amp sounds so sweet. Can someone confirm that the FX send jack is post tone stack? In the pics the top left two 1/4 jacks and the back of the tray are the FX loop send and receive.
I'll post a shot of the tray :
