He said in the 95 GP that the Lab was sent into either a Crown MT600 or a MB 2:90. Since the 2:90 was not out when the first 2 albums were recorded, 1989 and earlier (according to replies to that question on the Boogie Board), I figured I'd try the MT600. It really sounds exact to me. I got the MT600 for $200, in perfect shape, a lot cheaper than a 2:90!
I was getting some extra breakup from my Marshall cab with 25W greenbacks so I went out and got the Peavey cabinet. I emailed Peavey support and they said this was most likely the cab he used, they weren't sure, but this is from a few engineers at Peavey who are huge Ty fans. The cab has Celestion G12K-85S speakers in it. I heard them described as, big tight bass, not quite as mid scooped as the 75W'ers, with good top end. Like a more tamed V30, which of course Ty has used for a while now. Sounded exactly like what I could use, with the L5 bass needing a boost. This was the final piece of the puzzle for me.
You are right though, the Elite and the L5 are the bulk of the tone. But you can't get there with the L5 alone, it has to go into a different power amp. I was going into a Yorkville Sound AP400 and back into the L5 speakers and it sounds really good too, except that the pots on the AP400 were too scratchy (20 years old) and drove me nuts.
As for clips, as soon as I started converting the Strat my camera broke. I am going to get (very soon) a HD video camera that takes stills as well, so I can take pics of the guts of the Start and I promise I will do a bunch of clips, all I've been doing for the last month is playing stuff off the first 4 King's X albums!
