People often complain about the limitations of the single tension tuning system seen on some older drums. But, in some applications, I have found the system to work quite well.
That Ludwig Junior bass drum I have is really a great sounding bass drum. I used it on a gig once with a Brazilian guitarist and the sound of the calfskin heads was just so warm and beautiful, I really started to crave that sound. So, I tried it in another couple "jazz" applications and it worked well. I had to be careful because all the bass drum had to support it was those little clip on spurs.
I think the calfskin heads are key to making the single-tension system work. Calfskins have a great tendency to "creep" out of tune, anyway. The single tension system enables the drummer to quickly bring BOTH heads back up without a lot of hassle.
Another great thing about a single tension system is that it basically serves to make the shell a true "free floating" shell. There is no better way to really hear what the shell can do than when it is freed up to vibrate.
I think that a single-tension drum which has been well-built with good, even bearing edges, could, for all PRACTICAL purposes) sound as good as anything out there.
Also, just for trivial reasons, I am amazed at some of the innovative tension rod designs I have seen on some of the older single tension drums. Even on drums that were considered as toys for kids, some of the t-rods are really cool and very efficiently designed.
I have even kicked around the idea of building a couple of drums m'self one day using a design for a single tension system....waiting for another rainy day, I guess!
Fans of single tension systems, anyone?
Dissenters? Tell me how I'm wrong! :Santa:
