Thanks! The hiss comes and goes. It's caused by the 'extra' Diapason notes for the Great/Swell, which live in the Celeste tone generator chassis but have their own pre-amplifier. Since Diapason goes down to C00 (32'), they ran out of room for C7-C8. Mostly these notes would be used in the Mixtures. I think it's a bad ground - thought I had it licked by replacing the audio cable, but I guess there's more to it. Adding in the reverb cuts the extreme high frequencies a bit, so I think it helps mask the problem on TH-cam. Much more noticeable in real life.
@@AdamPilbeam85 I noticed in some of the first few Allen organ videos, some of the higher notes had this strange kind of electronic hiss on them, wasn't consistent, and I think at the time you said it was Allens "Wynd" feature. Not sure what could cause a high pitched white noise, a bad ground would create like a 60Hz line voltage hum I would think.
Yeah, at the time I thought it was the Whind mechanism's normal effect. It technically still caused by Whind, but the way they inject random AC voltage into the tone generators - it has to be bled off to ground or you get more hiss than you should (per the tech documents). It's hard to know actually how much hiss there should be, since these units are so uncommon now, and a fully restored one that sounds 'new' is hard to find. I don't mind a mild consistent hiss, but this will build the more keys I press even with no stops on. Since it's just one tone generator chassis doing it, it's at least easy to track down.
Thanks! It IS from the TC generation, but it's a 'Custom' from that era. It's a little bigger with seven tone generators and a full set of intra/intermanual couplers.
Merry Christmas 🎅 🎄 ❤️
Sounds like a real Oboe! Nice
Great playing! Aloha from Hawaii.
Thank you so much!
I didn't notice much of a hiss, the organ sounds very good overall lately

This sounds quite good! Is this from the TC generation? The way you play it, it sounds nicer than Allens a couple of generations newer
