Should I add this prototype as a new item?

Hi, so I found this picture of Kerry King with the prototype of hhis signature amp . I know it's the prototype because that's what his signature Softube plugin is modeled after. I don't know if the circuit inside is any different from the final product, but it has a different graphic on the front and the switch for the beast mode seems to be missing even tho the controls for the beast mode are present. Should I add this prototype as a seperate item and add it to Kerry or is the difference so small that the final product is enough?

I generally submit such an item under the main one, unless there is a significant difference.

I'm with eyesee on this one, speaking generally. It's common industry practice to give artists several pre-production prototypes to vet and sign off on before their signature units go into production, so knowing a prototype exists doesn't represent anything unique or separate from the production model in most cases.

I didn't see anything about a prototype of Kerry's amp being used as Softube's development reference in what you linked, but my guess would be that if prototype hardware was used in that situation, it was so the Softube version could go into development well before the hardware version of Kerry's amp went into production... not necessarily because the prototype sounded better than the production version... but that's just an assumption.

Now, if an artist went on record saying that they were unhappy with the production version of their signature gear, and started only playing the prototype live and/or in studio, and trashing the production model in interviews... maybe THEN a separate entry for the prototype would make sense, because that would be critical info to have if you're trying to get closer to that artist's tone... but I've never heard of such a situation, ever, really.
