I use a mixed setup. The monitor out goes to a TC G-major with FX bypassed (mainly as level control and splitting). From there, one signal goes to the Return of my JVM410H and into a 1960 with a mixed Speaker configuration (2 X V30, 1 x G12H30. 1 x G12T75). The other signal goes to an ENGL 820 Power amp and from into a Standard 1960. The ENGL power amp sounds way more scooped with lots of low end thump and hi end bite so it even emphasizes the charakter of the scooped sounding G12T75. The Marshall power amp has more midrange punch and gives a lot of tone and definition to the other cab. It´s nice to vary the levels of both cabs.
Since the change of the monitor EQ i run it completely flat.
