I’ve been messing around with the #34 mod 800 model, probably my fav model at the moment... however, I noticed that if I engage a drive block in front of it for solo boost, when I disengage the drive block there is an audible bass frequency warble until I switch to another preset and back to the #34 800 preset. I haven’t had the chance to see if it’s in the axe fx 2 too, but in the ax8 is quite annoying
