The Story of GH Plugs and Cables

G&H industries was born 30 years ago.  The company was formed by Bob Ganger and Paul Haas.  Paul had been working as a manufacturing consultant with Proco Sound.  During this time Proco ran into problems with the grounds loosening up on the Switchcraft 280’s that they were using to make their instrument and speaker cables.  On behalf of Proco Sound, Paul worked with Switchcraft, visiting their factory and discussing the problem with their production people.  Switchcraft made many efforts to address the problem, but never got to the basic cause, the design and materials used in the plug.  Paul discussed the problem with Bob with whom he had worked for several years.  The problem faded but didn’t go away and in the meantime Bob and Paul came up with a simple solution, crimp the ground to the sleeve of the plug.  They discussed finishing the design and decided to use OFC copper for the hot conductor because of its conductivity.

When they had it complete they presented their prototype to Charlie Wicks, the owner of Proco Sound.    He liked it but was unwilling at first to change.  However very soon after that Switchcraft told him that if he didn’t like the plugs the way they were, they wouldn’t sell them to him.  He called in Bob and Paul and told them what had happened and told them to “Make my plugs”.  They formed the business in May of 1987 and set about getting tooling made, buying equipment, and finding vendors for components.  The first plugs were shipped in September of 1987.  That first year they sold exclusively to Proco Sound as they debugged and improved their production processes.  After that first year many other customers quickly came on board.  And soon after their first international customers

You can’t be in this business with just a 1/4” straight plug.  The next product to come along was the right angle plug.  The big complaint about the Switchcraft was loosing the screws that hold it together and the difficulty in soldering the ground to the steel case.  We came up with the RF2P that eliminated the screws and had an easy to solder to ground clamp.  It was patented and the first 1/2” profile right angle plug.

The stereo plug came next along with the high clarity mono plug.  The stereo plug was another necessary addition to the line, like the right angle.  But while we were doing that we made provisions in the tooling for the mono version which became the High Clarity plug.  By this time we had made numerous custom plugs with unplated copper terminals.   The lesson was that as we made connections more solid, improved the conductivity of the materials, and eliminated material transitions in the signal path the sound kept getting better.  The people that asked for them told us that they were cleaner sounding with a little less “attack” than the BF2P.  We ran them by musicians who didn’t know that we had done, they all recognized the difference immediately.

This was followed by the quiet plug.  Paul was visiting Proco one day looking at some inventory that they were trying to “unload”.  Among them were a few Switchcraft silent plugs.  One of the salesmen flicked the button a few times and it flew off.  He said that was why they were getting rid of them.  He said that the worked great, but sooner or later either the button would fly off or dirt would get in the contact and prevent shorting.  Paul asked is there a need for them?  The answer was definitely, and he went on to describe just how handy they are to have on stage.  It became the topic of one of our weekly meetings at the shop.  About a month later one of our employees came up with the idea of the sliding sleeve.  A few months later it was added to the product line, and within a year a major contributor to the line.

The dual Banana plug was first brought up by Whirlwind.  They wanted one that would take larger diameter speaker wire and take 30 amps.  Other customers confirmed the need and mentioned that the  springs on the bananas available often broke.  Paul had a sample of a lantern spring in his “junk drawer”.  It had been picked up at a trade show some 20 years before.  It was one of those things that you know the idea is going to find application someday.  This was it’s time.  The sculpting of the body,  the lantern spring contacts, two slots for using a wire tie strainrelief, and the clamp type termination make for a plug that will accept large diameter wire, fit in the back of an amp, and not break.

The TT plugs were another request from Whirlwind.    They wanted TT plugs that were solderable,  weren’t wire specific, and were shielded.  And by the way it would be nice if you could put two next to each other in a patch bay.  That last requirement made it a little tricky.  Standard threads wouldn’t fit, but fortunately CNC’s don’t care if it’s a standard thread.

Our first solderless plug came in the late 90’s.  Taking an idea from some plugs made decades before, it utilized a needle to make the hot and a mechanical crimp to do the ground.  The housing was pressed on.  It was the predecessor to X24 plug for Lava Cable, the patented Pure Plug used in (Clear Connect from Lava, Genisis Pure from Analsis Plus, and Greybles from AMX).  This patented plug represents the current peak in the evolution of our plugs.  Material transitions are minimized and machine crimped connections minimize contact resistance losses.

Over the years a lot of small changes were made and custom plugs created for specific customers.  There were a lot of requests for an XLR.  The challenge was, what can we do to make a real improvement.  As we gained more experience with materials and learned more about how little improvements in conductivity can be heard by the musician we came up with our first XLR’s.  The originals sounded great, but there were supply issues.  During this period the company was purchased by Abbatron in March of 2010.   Bob retired and Paul stayed with Abbatron to provide continuity with G&H customers, and on new product development. The XLR went on hold while the bugs of moving a manufacturing operation were worked.  The shells were redesigned,  other parts retooled and the new XLR was finally released in 2013.  The Tellurium Copper pins and Beryllium Copper sockets produce and cleaner more natural sound than others on the market.
