Location: North Carolina | Hi guys,
Ovation mentions on their website that when using an G-to-S XLR such as P/N 9658-0 with the OP50 pre you don't need to activate the pre with a dummy plug. Anybody have any idea where these are available? Thanks.

Location: Scotland | Al's a dealer, he could get one for you. Or you could modify a standard cable. Neutrik plugs have a tag between pins 1 & 2 for the purpose of grounding to the plug shell. Just take some hook-up wire and short from pin-1 to the tag, job done. If you can't find a cable with Neutriks buy any XLR-XLR and I can send you a Neutrik female plug. You can do this with any make of XLR plug but Neutriks are the most reliable & easiest to work on. |

Location: North Carolina | Thanks Paul,
I am using CBI cables with Neutrik plugs so I should be able to modify it. Do I short the pin1 to tag on the male end that plugs into the amp? What kind of wire do I use and how do I attach it to the pin and tag? As you can see, I am an electrical novice. Thanks again for your help.

Location: Scotland | Do the mod at the female plug (guitar end) only. Any wire will do, a piece of pickup hook-up wire or some of the cable screen wire. Solder one end to pin 1 (pins 2 & 3 conductors will have colored sleeves, pin 1 will be bare wire) then solder the other end to the tag between pins 1 and 2. Keep the wire just long enough so it doesn't touch & short out the other pins. I realise here that I'm assuming you know how to solder & have an iron. If not it's a five minute job for anyone with the gear and basic skills |

Location: North Carolina | I went home last night and lowered the sleeve of my Neutrik connector and saw the pins and the tag. Doesn't look too hard. I'll do it as soon as I borrow a soldering iron from a friend. Thanks for your help, Paul.

I understand that the contact points have to be clean. What do you mean by "Flux"?

I think that only applies to copper pipes. |

Good luck, and no caffeine!

Location: Scotland | The other important points about soldering are: make sure you tin both components to be joined and make sure you keep the components absolutely still while the solder cools. If they move you'll get a dry joint which will eventually fail. Dry joints are dull grey, a good joint is shiny silver. Under-heating the components can also produce a dry joint. Also make sure you heat the job & allow the solder to flow onto it rather than trying to carry blobs of molten solder to the job on the iron tip, which is how most novices attempt it. |

Location: North Carolina | Just dropping in to say I finally got hold of a soldering iron and successfully made my very first ground-to-shell connection. I used a piece of solid copper wire stripped from an old cable TV cord to make the connection. Wasn't too bad though it did require 3 hands. Thanks to Paul T. and his advice on how to do it. No more dummy plugs for me!

Nothing major, just 220v potential between yer lip and the mic when you're holding your guitar.
Isn't that why they decided to lift the ground in the first place? I mean... they USED to all be shell to ground (pin 1) back when I made em (think like 1975) |

Location: Madison, Wisconsin | Thanks Paul! I'm a electrician by trade so I really wasn't too worried about the voltage thing. I was more concerned with what, if any, effect it would have on the PA sound such as noise or buzzing. |
