Supro model names can be confusing and inconsistent - this is it, right? (only image I could find!)
I think it's just called the Sonic 30.
To post an image it has to be online somewhere (photobucket, imagecave etc or just another website) and you link to it with bb code - click on the Img button, add the url of the image and then click it again to close the tag.
To answer your question - I think it's basically the same pickup, but the ones without adjustable pole pieces probably sound a bit different. Adjusting the pole pieces makes a big difference (if you have them).
PS there's another, fuller post about images if my instructions are unclear
