Unfortunately, the Melodia bass pipes are the least accessible portion of the least accessible rank in the organ. One of = these days when I'm feeling really ambitious, I'll unrack the mid-range pipes to access the basses and I'll let you know what I find there.   -Brian Graham

They are actually a touch faster than their full length = counterpart. Remember that in voicing the terms "quick" and "slow" are used to denote = a characteristic of flue pipes. If the windsheet is too far in the pipe = will be "quick" and conversely, if the windsheet is too far out the pipe will = be "slow." How the pipe reacts is a major element of how the wind is = presented to the pipe. Wurlitzer chests are the best for the electropneumatic = chests because they give a response very much like a tracker pallet valve. When pipes are voiced on the correct wind pressure and for the action they will = be coupled to, they will speak quickly and with the proper timbre. Mix and match organs sometimes leave their owners wondering what is going on with certain pipe speech oddities because the pipes were not voiced for the = type of chests they sit on.   Al Sefl Guaranteed to be correct 50% of the time...........

On my Estey #2775, (1928) I found = several haskelled pipes that had minute vertical cracks in the top of the = qualifying tubes, once I sealed them up, the "volume" came right back as well as the somewhat slow coming on to speech condition. Large amounts of dust/dirt = tend to obscure the small cracks, but they certainly make a difference. I also found that displaced harmonic bridges from wood dry-out and nail/screw falling out problems also affected the haskelled pipes. I recently set up a lower octave of haskelled basses on a Kilgen offset chest. There was no perceptable difference in the speech on the Kilgen = chest as on the original Estey chest, the wind being the same. Regards, ---Roc L V Rockafellow
