How do you patch an effect into a Fender amp that has one input for effects. The input says "in/out". I assume it requires a 1/4" stereo plug? But how do you loop it through? There is no "power amp in". There is a "line out" ???
There must have been a special fender "Y" chord for this application?
Thanks

If you're referring to old blackface or silverface reverb amps, the in and out RCA jacks are to connect the chassis to the spring reverb pan. They won't match the levels or impedances of other effects devices without inserting line matching trransformers designed for that purpose. |

Hi Mike,
The amp is a Fender 75. It has a Reverb in and out(two jacks), but also an effects in/out(one jack). Usually there is an effects in and out(two jacks).??? I'm thinking this is a stereo jack and Fender possibly sold a special "Y" chord to use with stomp boxes?
Thanks

Hi Dennis,
I am not familiar with the amp you are talking about, but I can take a guess at what you need. On recent Fender amps that do this, we suggest an "insert cable," which is like you describe. It is a Y cable with tip,ring, and sleeve (2 black isolation areas on the metal plug) on the common end. This is the portion that you plug into the amp. The other 2 plugs are simply tip and sleeve (one black isolating area), which go to the effect. You have a 1 out of 2 chance of hooking the effect up correctly the first time without further analysis. I don't believe it's a real obscure item in the overall world of cabling, as I have seen it on other sound equipment. I think you can find them at Guitar Center or in the catalogs. You might find it or be able to order it at Radio Shack, too. Regards,
Sam |

A six foot insert cable is included in one of my Box of Cables still available. |

I think Sam is right - it sounds like an insert cable application. They're easy to find if you don't want to make one yourself. |

I just looked at the schematic and, if they drew it correctly, the send is on the ring and the return is on the tip. |
