Many, many hours. A good sign they're broken in, is that you don't have to keep retuning random reeds that don't stay in tune (played at moderate volume). I could also tell a maturing of tone, day after day.

Unfortunately, I'm putting the music down for a while. Got some vertigo issues going on at the moment. The slightest turn of my head, or any amount of concentration makes me want to throw up.

Dam! What's causing that? I have another friend going through the same thing right now. Suck. Hope you feel better soon!

Bad news Jim, i hope you get well soon ... Nout

Jim,
Sorry to hear of the recent downturn in health.
You've been really, really helpful in my learning process and I appreciate it. Not living in Cajun country and being steeped in the culture, I need the contacts and help. I'm also glad that you can distinguish my newness to the accordion, from being "retarded." It's important that people outside the culture love and share this music in order for it to survive.
I love how deep you're digging into these accordions! Tuning reeds and swapping reeds, etc.
Keep having fun playing and sharing my friend....

Last time I got my accordion tuned I was talking to Marc and he asked me if I play outside a lot. I answered him no, i live in Chicago. But I didn't really think to ask why he was asking. Does he tune slightly differently if you play outside a lot ?
