you can get an acetate done at numerous places, it is no different to a carver, if for your own listening pleasure fine, if sold or played out it is no different to a bootleg. If it is of an unisuued or cut from unissued master tape, again no problems with those. Don't know how you can suggest what you have is any different to a cut/carver or whatever you want to call them. People have been cutting acetates for years and years, carvers are simply more modern method.
You can or could still buy original Virtue blanks and get stuff cut to them.
There are loads of acetates and carvers of Sandi Golden, my mate had Robs copy for a while before it went to Richard S and cut and acetate. Rob no doubt did at least one.
Mello Souls is btw a Virtue recording, it says so in the run out.
