On early Dynas (C0B) the bottom hoop did have 2 removable pieces on either side of the hoop. As the years progressed, the hoop became one piece entirely. I have a Dyna with a 20,000 range serial, and I have the removable piece type. I have other Dynas around 50,000 that do not. I would guess yours is in the 70-76 region. Very early Dynas had the clockface strainer, if yours has that then approx. 64-67. There was a slotted snare guard that could move up and down as well. If your bottom hoop is all solid and an oval badge, it might be one of the last ovals before the change to the "Big R" series.

Others will chime in, Tommyp is pretty knowledgeable in the Rogers area, he is man consumed by the Rogers bug, helluva guy too.

Serial numbers are odd with Rogers, from what I've heard. I don't know of anyone who has a date/time stamp of serials available, if there was one, I'd be willing to have one too.

BTW, they are great snares, IMHO

kjklives2ride!...

Actually, yes to both your questions. What is the serial number of your Dynasonic? I have a very accurate listing/compilation of number's/dates. These were put together over a long period of time with a LOT of personal research as well as input/discussion with a few of my Roger's bretheren. What's your serial number? Regarding the snare frame:

The design was indeed changed, and I believe at around 1976 with the introduction of the Big "R" badge as the actual snare guard was also changed this year. This design stayed in place until the drum was discontinued.

BBK!...

Thanks for chiming in and the nice words! Most certainly want to see your Blue Strata Pearl set when you're finished!

Tommyp

the serial numbers of the two I have are

9378

51255

also another question..the snare frame on one of the drums does not set flat..appears to be slightly warped..been having some problems with setting ;up the snares..I assume this would affect it..

at first glance I would would lightly sand down the bearing edges on the snare frame to get a flat surface..do you agree..right now you have partial contact from the snares

kjklives2ride!...

Dating info:

Dynasonic #9378 falls squarely in the 1966 model year, and if a COB, should have 7 lines and Beavertail lugs

Dynasonic #51255 would be right around 1974 and be a 5 line with Beavertail lugs as wood models were discontinued a year prior.

Regarding snare frame warping/set-up: Yes, you are quite correct. IF the frame is warped and doesn't lay FLAT, no amount of tensioning/tuning will ever get the drum to play/sound right at all. The snare frames have to be perfectly flat... otherwise their ability to make contact with the bottom head is compromised and you end up with a "buzz bomb" for a snare drum. I have been most fortunate as all my Dynasonics... ( two wood and two COB ) ... all have perfect snare frames. Your thought to "square" yours up is correct. Do what you can to get it to lay flat... it will make ALL the difference in the sound of that drum! NOS Rogers snare frames can be still purchased if you have no success, but they are a tad pricey... in the $100.00 range. I'll attach a few pics of my 1965 Rogers COB/7line Dynasonic... your 1966 should look like this one.

checking out the slotted screws on the strainer and butt ends for the snare strings..are they the original..are they chrome or just clean stainless steel..I have been looking for replacement screws because the heads on mine are a little beat ;up and I could not tell if they were originally chromed or just oncoated steel

kjklives2ride...

All my Dynasonics are original with OEM parts... so ... the tension screw is just a regular steel screw with the very ends chrome plated, most probably for aesthetics I would think, thus, you could easily get a replacement screw at any well stocked hardware store as it is a standard American thread. These Rogers Dynasonic tension screws do come available now and then on eBay, and if memory serves, there was a guy making replacements out of stainless steel with a BIN price on them. They looked quite nice!

Tommyp

thanks all for your input...

Hi everyone -- my first post here but surely not my last. I know you must get these all the time, but I am trying to get a hold of a 5" COB luddy/rogers snare relatively cheaply (not easy in Australia) and someone has listed this as a "Rogers 380". It looks like a quality drum but have no idea how to identify and couldn't find it in your identification section which is probably a bad sign.

If anyone can help it would be much appreciated and probably save me from overpaying for something that won't give me the sound I want! From what I read the 380s may have been a substandard Japanese manufactured drum?

Thanks,

Adam
