I use a dual amp setup
I have two similar amps and I pan them hard..
5153Red left / VH4 ch3 right
another great match up is the 5153Blue and the VH4 ch3 or the Herbert ch2+
for funk I've been using
Hiwatt Normal left / JCM800 right
you could replace either of those with the TripTik Clean
for this to work, you must dial in the low end so that both amps produce very similar amounts of it..
if not, the tone will lean to one side in the mix
How do you know which amp is using each cab on the stereo cab block? Since there is no visible way to tell, or you just set amp L and amp R and it goes directly to cab L and R?
I don't use dual amps myself but there are some great example presets.
There's one among the Deftones presets. A crunchy Boutique accompanied by a high gain amp in the background. It's heavy but retains note definition.
IMHO dual amps should be complimentary. Can be clean & crunch, or mid-heavy & bright, etc.
