I've been aware of Tony's amps for about a decade now, but only plugged into one a couple months back at a friends place. 'twas an EF86 model with tremolo. I was absolutely blown away. The cleans lush, the drive perfectly rich and chimey. My oh my, what have you done Mr. Teixeira?! I'm 99% set on the EF86 model w/ trem, but was hoping that those of you that've some experience with it and the Bernie could chime in. What are the differences, tonally, between the two models? I want the one with the bigger clean sound and chimier/brighter gain structure. How do these things take pedals? Am I out of luck if I require any truly clean headroom with a humbucker guitar? Any feedback would be greatly appreciated- been talking to Tony and hoping to get on the list very shortly.
