Well, I finally took the plunge and pulled the trigger on a 1987 SVT "skunkworks" head. The deal thread is here: http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&rd=1&item=330214478445&ssPageName=STRK:MEWN:IT&ih=014 I'm really looking forward to getting this bad boy, and setting it atop the requisite 810 cabinet. I'm currently running the CL, so I'm pretty anxious to compare the tonal differences. For those of you with the experience, how would you compare the "skunkworks" head to the modern SVT VR? In doing a search, I found several comments to the effect that the "skunkworks" head gave a good run at the original 70's era SVT's, but that there were some tonal differences. Well, I can't wait to get her to my bands practice space, and fire her up! And I will certainly post my observations and experiences comparing the "skunkworks" to my CL.
