I’m really digging my axe fx iii I have used pedals for a long time, but I can see that the fx iii is going to change all that I have a lot to learn.I am with Cliff on this. Since I got the AXE3 I dont use drive blocks for heavy and even dirty tones anymore. I still use one on for my cleanish sound. Just to add a little grit and shimmer. Cant get that sound without an SDD preamp drive block.
