in 1997, I bought myself a Chieftain Low D non-tuneable. It cost 55 punts - at the time I could have bought an Overtone with the same spec. for 90 punts.
On some thewhistleshop.com, I see chieftain law d non-tune for US$187 and the Overton for US$190. When I bought my Chieftain, I was told that it was a cheaper alternative to the Overton, but that doesn’t seem to be the case now. Has Chieftain gotten better or has Overton gotten worse?
