Want to know if that Hammond you have is a B3 or an A100 or just an M2 ? And is that Leslie 120 you've seen for sale the same as a 122 ? This is the app to look at!
A standalone version of the main model list found at http://www.jackhollow.com/hammond/modellist/index.html.
NOTE - first time run it will take a few seconds to create the main database. When on wi-fi, will create a cache of image thumbnails also, hence NETWORK permission required.
**** If you find it crashes when selecting any organ etc, try uninstall & reinstall (version 110 and above should avoid this problem though) ****
