[HAM] A-100 reverb unit location

[David Anderson]

Mike,

Spring reverb tanks are built with an optimal mounting position in mind, and it's best to stick with it, if possible.

If you look from behind the organ, the A-100 reverb tank is mounted vertically to the side of the organ. I can't tell from photos if it's input or output side up. 

Now, you can actually have a reverb tank made to your specs by Accutronics; I noticed recently that they have an eBay page where you buy one and send them the information on what you want. You could even go with the larger Type 9, three-spring tank, which I'm told gives a longer, fuller-sounding reverb.
