If your talking about the "new" old style, The one I have isnt quite loud enough for me. Its made out of red wood burl so an acrylic old style will be a touch louder. Good sounding call just not enough reach for me.
I've got one from about 1987. It was the only style they made then I think. I don't know if that's the model y'all are talking about. It's very loud with a fantastic top end and feed call. I can't get much out of the bottom end of it. I had Butch try to get a little more bottom end on it for me about 5 years ago. It's dang near a contest style call.
I had one of the NOS. Sounded good, will do the cajun squeal with ease, but like pimp said, its a finesse call. I don't have a problem with wood, and have had a few in the past, but the acrylics always sound more crisp to me.
I'm an acrylic guy myself. Nothing against a wood call but I just don't like the way they tend to swell when wet and overtime I've had to have the hole in my insert drilled back out. The wood wants to expand. To me a wood call tuned right has a true duck sound like no other. Acrylic seems to be little louder and will have the same sound if its wet or dry it doesn't change.
I've got an old original Butch made for me as a Christmas present one year. Sounds great but not loud like today's calls. I learned the hard way to pull the insert out right after the hunt.....wood will swell...!!
im not a fan of the calls....bought several over the years Meat Hanger DRT XLT....always hang and lock up on me....to much whine and flat...not enough rasp...personal preference and opinion....i do have an old poly double reed echo timber ive had for year locks up when u get down on it but sounds good other wise....just not an echo fan....period
i had an acryllic old style for a little while. didnt fit me very well....tended to overblow it a lot. its a real easy call to blow, doesnt take much air at all. other than me overblowing it....it sounded really good.
