I'm trying to decide between these two, and wondering if anyone out there has compared them. I know it's not a substitue for the actual amp, but I have already have 3 amps and plenty of "amp-in-a-box" pedals, including several that can also be used as a preamp. I'm getting the AMT P2 for 5150 gain, and want something like Diezel VH4 or VHT Ultra Lead tones as a contrast to the 5150 tones. Has anyone got experience with these? Thanks in advance. (I'm also considering the Diezel VH4 pedal, which I'm sure is better than the D2, but costs quite a bit more).
