Which Ampeg profile was it you were looking for? I don't see any factory bass Ampegs in the reference list that aren't named "Amp pig". I've went through gobs of guitar profiles but the very first bass profile I ever tried is still the best one I've tried. It's an SVT that came in my Kemper, I can't recall the name but I know there wasn't "Amp pig" in the name. I filtered bass in the reference list and all of the Ampegs read that. I'm sure mine was a factory rig but I didn't find it on this list filtering bass.
Same as me and stuck with it after I stumbled across it, it's likely the Amp Pig by TAF. My memory of the name failed me but the memory of the tone I got when I tried it, did not!
