I currently run a FDII in my AC30cc2. I like it alright but I read a lot about the Crowther Hotcake being the OD for the AC30. Can someone who has used both in an El84 style amp give me some comparison notes? I am not totally unhappy with the FDII but I am looking to better the OD I get through the amp. THE BIG QUESTION Which sounds better through an AC30, a Crowther Hot Cake or a Fulltone Fulldrive II (mine is the older blue with cream push/pull comp cut volume knob)? help is appreciated.
