I just happened to find out by accident that when you have 2 amps / cabs in parallel, usually when you switch from A/B to A+B the volume gets louder, but if I use the vol/pan block after the amps and pan one cab left (setting channel A of the vol/pan to left only) one cab right (setting channel B to right only), if I engage both amps and set channel 3 to stereo and center pan both sides within the vol/pan block, the overall volume is equal to (if not almost lower than) the single amps on channel A and B. What’s the principle behind this? It’s very cool, but I’d just like to understand the principle behind this!
