No, EBuss is very hush hush about who makes the chips. I’m GUESSING from what’s been said, they changed to a different chip maker for the Detonator and DB3, not sure about the Tac (too big for me, so I skim past any info). I know the last two mods plus the DB LE had heavy Chinese ties, because the foreign sites released preorders/pictures at least for the LE before Squid was ready/had a chance to do it themselves. There were some preproduction mock-up (Detonator?) one onlys that a Chinese site sold (that Squid had not decided to use because they didn’t meet expectations), but they didn’t have the SI name on them.I don't suppose you've ever seen a fanboy mention another place to get one of those chips, have you?
People have offered or asked for mods for parts on SVG. Some want dead units to take and custom paint. You might be able to recoup some $$ selling it there.
