They all sound solid to me, and if I had all 3, someone would be hitting the road. For me, I have a MC2 and it's a keeper. The rhythm channel on the Wizard destroyed the Bogner TJ's clean channel that I used to have. I have used the MC2 live at about 3 gigs, and it really punches it's way through the mix like no other amp I've ever had. They are also a beauty to behold under the hood. Never owned a Hagan and thusly can't attest. The only struggle I have with the wizard is that at times, I wish the gain had just a fraction more. Other times it enuff. What's weird is I have a Steinberger GL2T ala EVH, it an original mid eighties one with original EMG's. I'm not really a big EMG guy, there ok IMHO, but I fired up the 'Berger thru the MC2 the other day and was floored by the amount of gain that the amp was giving me with this guitar. I'm thinking that the active EMG's where just the right level on the input signal to the amp to give the Wizard that extra bit a Meltdown that I at times felt I was missing. With other non active pickups, a pedal up front gets u there no prob, it was just cool to see how the EMG's pushed the Wizard it to full on Palm mute, turd shaking in the lower intestine mayheim.
I might try and do a comparison of this and post to demonstrate.
