Ya, they do, except I believe you used an Alpha 8a, didn't you?
Every mod on Vesku's site came from the Talkbass thread. He should have mentioned Talkbass. Someone else on the thread suggested the Fane...
I modeled the Alpha 8a and a few others, and liked it, but didn't use it. It did become a popular upgrade.
I was curious about neos and wanted to try one, but didn't find the right one. Not many 8's, and any that I found were cost too much. Remember the neo price hikes. Then I was at GC one day, and I saw a BA108 right next to a GK backline 110. The 8 inch Ampeg was actually bigger than the 10 inch GK. Hmm. A 10 might fit... I modeled a S2010 basslite in it, and it looked OK.
Later on, I found a nice neo 8. Dave at Avatar had an Eminence 8" Neo Woofer 4 ohm, 150 watt speaker. It works well. I don't know if he has any more.
