Hi, i bought the Radial Dual A/B box and want to try a dual amp setup. I have different amps and 2 2x12 cabs. Yesterday i was experimenting a little bit, and found out (for me at least): 1) When you alternate between the 2 amps (with its own 2x12 cab) than you always have 1cab at the bottom and you cant hear yourself as good as the other amp with its own 2x12 at the top. But its a nice setup so far 2) If you switch in both amps at the same time, then something happens besides the "bigger" tone, something like combfiltering. Dont knwo how to describe but it gets mushy and not very well defined. I guess the attack is not time aligned so to say on both systems. - What is your experience with A/B setups? - And do you have some tipps how to integrate modulation effects ( WET/DRY )?
