More is not always better to everyone. What if Tim Ring is perfectly happy with his business volume as it stands?
I would have to believe that is the case. I can't think of a better reason not to promote it.
Ring Engineering advertises reasonably heavily in MRH. Speaking as a small business who has advertised in MRH, I can tell you, MRH is quite capable of overwhelming me with business. In fact so much so that I had to considerably scale back my advertising in MRH.
I don't want a bunch of employees, so I have to work at keeping things manageable in my own business. It's not hard for me to imagine that Tim Ring is in the same boat. Although I would like to see him have a few more employees, so he can spend his time developing instead of producing an supporting, I imagine the advertising he does do keeps him very busy as is.
The reason for not advertising in MR? Easy, why spend 3K on an ad that will simply overwhelm your resources? Until Tim has an army of staff and equipment to handle the calls and production, I'm sure he wants to keep the growth under tight control.
Regarding having a booth at a show, there would be nothing stopping a retailer such as myself from taking RP to a show, if I had time to attend shows. (Thank you MRH!)
Regarding MRH, Joe Fugate has expressed interest in running an updated story about RP to me. I've been waiting for the next generation of sound and such to arrive before tackling the subject, since currently it's not that much different than the original product covered in RH a few years back.
A story about Lee's layout and his RP experience would certainly be welcome at MRH.
