No idea. I will say this thing sounds phenomenal with the level 1 volume. Could it do better still with the upgrade? Speculation at this point. I'd like to hope it does give some improvement but is it worth the cost? Dunno. Personally I'd rather have it now but that's just me. Check out the Violectric USA website and you can play with configuration options/see prices. The stepped pot is an in-house creation and is not yet available right this second.
