Obviously with the AF3 you don't really have to have a base tone the way you would with a traditional amp/pedalboard setup, but I'm sure I'm not the only one who has a default sound that covers most of their needs. It would also be helpful to know what instrument and genre you're playing.
So, what is it?
I mostly play in a tech death band, so I've been really flirting with the Thordendal stuff to get really tight Recto tones with my PRS Cu24. That being said, the pushed AC30 with my Telecaster is a surprisingly versatile sound that I've been loving for black metal stuff.
