Well, it’s not exactly a perfect comparison. I just happened to play the same sets on both pipes in recent days. Here’s the skinny:
1960ish Sinclair drones with Redwood bass + Rocket tenors (no markings) + original Sinclair chanter (though carved) with Husk chanter reed = 467 Hz with a clear high A
1974-1983 Glencoe drones (1 of about 250) with Canning bass and tenors + Colin Kyo chanter with Gilmour chanter reed = 476 Hz with the crowiest high A ever (I just can’t throw this reed away, all the other notes sound so good)
Glencoe pipes were made by Matt Marshall up in Ontario after having immigrated from Scotland in 1974. Matt worked at R G Lawrie bagpipes before moving so I figure his pipes are of some sort of Lawrie specification.
It is amazing how much easier the Colin Kyo chanter is to play! The Sinclair is my band chanter so it gets a lot of play time. But today, I whipped out the Glencoes with Kyo chanter and my fingers were like, “Aaaahhhhhh, I know where the holes are!” Had a blast.
