There is nothing wrong, illegal, unethical or whatever else with the JangleBox.
The Basics
========
The sound trying to be achived from the RM circuit is ? ...not a Rickenbacker
invented sound but, the high compression sound created by the studio compressors
(you experts out there will have to help me out with the brand name of these
compressor(s) ..they certainly were not Rickenbacker

)
Copyright and all that legal stuff
========================
Much as been mentioned about "copyright", "properly-registered intellectual property" ...
Don't confuse the shape of Rics which _is_ an infringement to the electronic circuitry.
What is copyright ? It's easy to google to find out

...in this case, what is
copyrighted, is the circuit diagram:
http://www.rickenbacker.com/pdfs/19515.pdf
Simply, if i took that diagram and posted it on a website without Ric's permission, the
$lawyer$ would be knocking... but, you can't copyright an idea, technique, principle...
....does RCA make the only TVs ? (actually do they make TVs anymore ?

) ...does Ford
make the only automobiles ? ...anyway, you get my point
The Circuits
============
ok...elaborating on the above, what about this, ...again, take a look at Ric's
compressor schematic here:
http://www.rickenbacker.com/pdfs/19515.pdf
...after a bit of googling, take a look at this one used by DynaComp and a variation used by Ross:
http://www.geofex.com/PCB_layouts/Layouts/d&rpub.pdf
Well lookie here ! ...even an electronic hobbyist can tell you these circuits are all virtually
identical ...The clamping diodes, the biasing being fed back to the op-amp (or any active component
used) These are all common "techniques" in compressor units ...you can easily find other schematics
that may appear different, but a closer look would reveal they also use the same ideas.
I never heard of DynaComp suing Ric ...DynaComp can't...there's _no_ infringement. Whether the
circuit is the same or not, it's irrelevant.
BTW, i tried to point out the above last spring in a Ric forum thread, only to get my post pulled.
Being in electronic hardware design way back, for 10 yrs, one of my concerns was $lawyers$ giving
false hopes to Ric for an unfounded case. I also mention in my pulled post to please dont get me
wrong, i certainly agree with protecting rights and admire Mr.Hall for _many_, _many_ things.
>If you are concerned about the JangleBox being a clone of the RM circuit then why don't you make a
>unit (or commission somebody) and sell it yourself?
Most likely to protect the value of the RM guitar...exactly why they're against Janglebox.
i phoned Ric in the later 90's asking this question when i tried to see if i could order
just the RM board

...was told there will be no after market.
"Now what is it about the JangleBox that makes the Rickenbacker experience more fulfilling?"
as mentioned in a previous post, i also agree that 360/12 -> Fender Reverb Twin -> JangleBox
nails the Byrds/Beatles sound ...better than a VOX AC30 (which i tried) IMHO.
