I just got this back from Mark. It arrived today and it is a killer sounding amp. It was a long wait, but the end product was worth it. It is very similar to the CCV set up.
Back looks like she has been cobbled up. The toggle switch holes look like shit and the magic marker. I guess that is not the point. as long as it sonds good.
I agree about the magic marker. I am going to get a label maker and put on some labels so it looks better. I gotta say, Mark did a great job with the mod. It sounds huge and it has that Cameron grind and touch response to it. I love the amp.
