Hammond b-3 organ

Of course, Jimmy Smith is synonomous with the B3, but don't forget Brother Jack McDuff and Charles Erland. In fact, any time you get a chance to see a "B3 group," take it. You won't be disappointed!

For historical reference, my aging brain recalls that the A-1 was the first Hammond. The A-3 was the precursor to the B3, and simply lacked the lowest "octaves" of reverse-color "presets". The E added percussion. The H added reverb, LOTS more percussion, and perhaps an added odd-order (black) upper-harmonic drawbar (1.125'??).
The M and L were smaller double 44 instead of double 61
models, and had a short pedal set instead of the full two octaves long pedals.
The enclosed speaker in these larger consoles didn't go below 40 Hz or so, so Hammond never bothered with a 32' drawbar. The speaker couldn't produce the bottom of the 16'
(first brown) drawbar anyway. Cheers.

Funny to see this pop up again now, since I just sold that M3 a couple weeks ago, which I never did get working! (Did make a whopping $35 profit on the deal though...The guy I sold it to claimed that someone once *paid him* $300 to haul away a perfectly good B3!)
