Beautiful tone, but really loud! They'd probably work OK on 6-7".     At 12:00 AM 9/19/02 -0400, randy wrote: >Dave, > >Go for it!

The discussion was about how to move the bass = offsets off the tremulated wind, and the suggestion was to use the 12" pressure = and suitably close down the pipe toes to compensate.   Depending upon the softness of the coverings on the pneumatics, I'd be a bit concerned about trying to run them on "low" pressures like 7". Even a Wurlitzer residence organ on about 8" pressure would have had static wind of 10" to 12" available.   The best bet would be to try it. Perhaps even a "clean" shop vac (!) = could be used to produce a small quantity of (noisy) high-pressure wind, = anything that would let you give it a try.   Larry Chace

Some of the more common ones I have seen have a full scale of 2",3", 5" ,10" or 15" w.c. The gauges have a 1/8" fpt fitting for a hose attachment .   Olliff Weldon
