I own a B3 and a A-100 Hammond organ and I can tell you for a fact that they are actually virtually identical schematically speaking. They were both made by Hammond but the only difference is the cabinet. The A-100 has an internal speaker that the B3 and C3 models don't have because it was designed for home use. (most people won't have a leslie at home) The "B" model is the designation for "Bar". The B3 is on legs and isn't skirted. The "C" model cabinet is designed for churches. It's skirted to the floor to keep those naughty people from looking up the organist skirt!!!! All three models internals are 100% interchangeable with the exception of the internal speaker within the A-100. In my studio I have a A-100 paired with a 122 Leslie. I also have a custom made back for it because the A-100 having been designed for home, was intended to be pushed against a wall so it didn't come with a fancy cover on its backside. I'll never sell either my B3 or my A-100!!!!!! Awesome sound that's just not easily replicated!!!!twistedtom wrote:Prime mover I played in a band with a guy who had a B3 it was a monster to have to move. He also had a Hammond A, made by the Hammond Watch Works Co. They could not call it an organ until after Hammond had a competition with a organ of the time; after the hearing test they got the OK to call it an organ. This is according to the owner of the Hammond A; maybe I will Google it.
I had a Fender Roads 88, I sold it as it was so much work to keep up. I see they are making them again and charging a good amount for them.
I have a couple of pics of my studio on my website. My studio has changed significantly since these were taken but you can see shots of my organ. http://www.newbp.com
