I once owned a full set of Overtons (D to D), but they were all non-tuneable; never played a tuneable one. Can any of you Overton players advise whether there is any significant difference to the tuneables?
Philo
Yup, they are tuneable. 
Loren
Okay, seriously…
I only have one Overton tuneable, a Low D, and any differences between the way it sounds and plays, relative to the other Overton Low D’s I’ve owned/played, I would attribute strictly to voicing differences between whistles.
Hope that helps.
You never can REALLY get those Overtons out of your blood, can you Phil?
Loren
I own only non-tunable O’s. I’ve played tunables, but didn’t notice a difference. So, I think Loren has got it right. (Wow, it felt really weird writing that last sentence. 
)
Missed that one…was it “I promise to change my avatar and stop being directly responsible for putting millions into the pockets of pharmaceutical companies for headache pills …”
Thanks guys. And yes, Loren, I am feelin a sense of longing for my old Overtons, and perhaps…WHOA is definitely me
Philo
It’s kinda an inside joke for Loren & me, and some of those who’ve been around a bit longer. As for the headaches: Pfizer is my middle name…
