Topic: Goodrich Curly Chalker model volume pedals |

Many years ago Goodrich made a Curly Chalker model volume pedal. The first ones were powered via a 120-volt cord and had a small “no-loss” circuit board that was similar to the 9-volt powered one in the 6122 model. Apparently, the circuitry failed sometimes and owners did a conversion of their Chalker pedal to the simpler model 120 design.
It’s interesting that Goodrich made a second version of the Chalker pedal, perhaps in response to the problems players were having and the fact a 120-volt-based design might prove unsafe on a wet stage. At any rate, the company dropped the power cord and circuit board and added a taper control. You can see that taper control in the second photo below. Both models had a switchable tone control. Either version is rare.

The "Tone" control looks like the (Weldon) Myrick mod that adds a tone control to a volume pedal. Except there wasn't a bypass (On/Off) switch in the Myrick mod.
I did a lot of that mod to volume pedals in 71/72 when I worked as the amp tech at Little Roy Wiggins Lower Broadway music store. |

Jack,
Just out of curiosity, Weldon almost always played an Emmons which had a tone control already. Any idea of why he would want on in his volume pedal as well? |

I had a Goodrich pedal at one time that ran on 120 volts.
I sent it to Goodrich for some service work.
They wouldn't return it to me.
There were users of the pedal that were getting shocked on a wet stage. It got to be a liability issue.
They gave me credit on a new pedal.

The stock Emmons did not have a tone control. All of them that I converted (added the Myrick mod) were Emmons volume pedals.
Where I worked, Little Roy Wiggins' "Music City" music store was the official Emmons dealer for Nashville. All the Emmons volume pedals we had in stock did not have a tone control. I just looked at an old Emmons catalog for the early 70's era and no mention of a tone control on a volume pedal. |

I have an old 1620 Goodrich pedal that I bought in the 70's.
It had a tone control circuit in it and ran off a 9 Volt battery. A year ago I could not remove the scratchy sound in the pedal. I tried replacing the pot with two new pots and it still had the scratchy sound. So I removed the circuit board and kept the new pot and no more scratchy tone.

| I think Jack Stanton’s question was in regards to the Emmons guitar having a tone control, not the volume pedal. Why do you need a tone control on the pedal when you have one on the guitar? |

| Doesn't the "tone" control on the pedal actually affect the volume pedal's taper, unlike the tone pot on the guitar itself? |

| There's a taper control and a tone control. The tone control is useful for guitars that have no tone control. The taper control is there so that players can adjust the taper action. (The controls are independent in action, if they're wired properly.) |

As Greg mentioned its not a true "tone control" as its only an extra pot. There is no capacitor associated with the pot like a tone control has.
Maybe it should have been called a "taper control" but it wasn't. |

Thanks for clarifying that Roger. Yes I was referring to the guitar, I should’ve been clear.
