| Has anyone posted a wiring diagram for installing an "in" and "out" switch on Goodrich active "10K model" volume pedals? Such a switch to bypass the circuitry would permit a user to have the best of both worlds: use their pedal as strictly a "pot pedal" or as an active pedal, utilizing its no-loss, buffered circuitry. ...Tom |

From what I remember about this pedal, the volume pot is in the active electronics and controlling the amplification, rather than the passive pot type control.
In order to use the pot, assuming what I think is correct, would require more than just a "bypass". The pot would have to be removed from the internal circuitry (connections) and "rewired" with a switch.
That would take more than a simple switch. |

| You're correct. Regular 500K audio taper pots (or the 470K pots I supply) will work just fine in these active (buffered circuitry) pedals. If it takes a double-throw or a triple-throw switch, so be it. I just suspect that someone has already "re-programmed" these pedals to have them function both ways. Before I figure out how to do this myself, I thought someone here on the Forum surely has done this already. Thus, I wouldn't have to "reinvent the wheel" to figure out how to do it. ...Tom |

Tom,
If I understand you correctly, the first thing the steel "sees" is the 500k pot. . . then the wiper of the pot feeds into the buffer circuit. If that is the case, and since Goodrich Pedals have one input and two output jacks, why use a switch at all? Simply connect one of the output jacks to the wiper of the pot. Connecting it this way you now have one buffered output and one dry output. If the buffer circuit is designed properly it should have no effect whatsoever on the signal.
All the best.
Sincerely,

| Craig, I was under the impression the pot was internal in the circuitry and not the first thing in the chain. The original pot in these is a 10 K pot, not the typical 500K pot. |

Who has the original schematic for this Goodrich pedal.....that would be a good start? As Craig suggested, a switch may not be needed if you utilize the second output jack. Even if simple switching is necessary, a switching jack may do the job.

Every now and then I speak too soon. Just got off the phone with Mr. Palenscar and found out the buffer circuit comes first in the pedal, and is followed by the pot. If that's the case, you could use either type of pot, but you would need a switch, or as Jerry suggested. . . a switching jack in order to have two different output signals, one buffered, the other one direct.
Placing the 470K pot first, followed by the buffer would be my choice, but I don't understand why you would ever want to run without the buffer.

| Kevin Ryan from Goodrich will contact you tomorrow Tom as we have one at the shop that has that configuration. |

i don't really understand that either.it's still a pot pedal and only improved with a buffer. |

It's funny that so many people seem to forget how much good pedal steel music was recorded without a buffer or powered pedal...like all of Charleton's stuff with Ernest Tubb, all of Lloyd's stuff with Charley Pride, all of Buddy Emmons' and Jimmy Day's stuff with Ray Price stuff, and all of Ralph Mooney's and Tom Brumley's stuff with Buck Owens.
Need I go on??? Do you guys actually think you sound better than those players I mentioned above?
Yep, you guys are definitely funny!  |

Who knows Donny?
Do you suppose they continued using fans once they found out about air conditioning?
It's a shame we can't ask them.
Imaging how wonderful all of those old recordings by Charleton, Day and Emmons could have sounded. . .
if only the equipment available in those days had been worthy of the talented players.
