I just got the plexi style black with gold piping. B+ drop as well. I wanted the cosmetics basic because LP is correct that a custom created headshell would be a little more difficult to move. I have no plans on selling mine anytime soon so.....To note, I did swap out the pre's as follows, You will have to pardon me on the exact numbers/codes on the pre's since the head is not right here in front of me.
V1 - Ruby HG+AC5
V2 - Ruby HG+AC7
V3 - Tungsol (really makes her dirty while maintaining that sweet clean)
V4 - Phillips NOS 12AX7.
Like you I was a little torn on the whole Ntro/QR mental debate. I love the sound of a Diezel (I know completly different animal)and know that he loads em up with Ruby's so I figured what the hell and went on the expierment trail. Results: More gain and a little darker with the overall tone. I also noticed that EQ now quells this mid thing that splawn owners bring up now and again. Me? I don't hear it. My main guitar is a custom made LP custom with duncan blackouts. Ya talk about pushing the shit out of the front end
