ok here is what i tried today. i have a fender hot rod deville. i set up the clean channel, then set the drive channel so it is the same volume as the clean channel. i have the footswitch plugged in, to switch between clean and dirty. now along with that, i have a digitech bad monkey plugged in which i want for my solo boost. on the pedal i have the level all the way up, bass at around 3 o'clock, treble at 3 o'clock, and gain all the way up. on the amp i have the clean volume set at around 5, and the master volume (drive channel volume) on about 4.5 clean and drive sound good. then when i step on the bad monkey, it barely gives any kind of volume boost, it just adds more gain (i want it to add a very noticable volume boost, along with gain) now i do not have the amp maxed all the way on volume, so there should still be plenty of headroom left for it to get louder. i do not understand. i have had this problem for a very long time, and some of you remember i posted about tbe same problem with my superlead plexi amp. all these boost pedals are reccomended, but they do not work anywhere near how i want them to work. i also have a keeley katana boost that doesn't work how i want it to either. my only last alternative is to just get a Marshall JVM 410 head. where i set up individual tones, and the amp also has 2 seperate master volumes.
