Smashing Pumpkins Tablature site: "Pumpkin Soup" houses over 150 transcriptions.
From Author of this site:
This site will no longer be updated regularly. I will not be looking for any new versions of songs on this site. I will not be looking for any songs that do not already appear. I may at some stage add new releases, but I make no promises! Further, I will not be continuing the mailing list. This is all due to other commitments which do not allow me the time to maintain such a large site.
