When I connect a second amplifier to the pedal I will get a hum from the second amp.
Anyway to eliminate the hum? Thanks. |

| Use a two prong adapter on one amp only to disconnect it's ground. |

First, subsitute another cable to the amp. If the amps have ground switches, try the different combinations. If that does not eliminate the hum, this should: Isolate the ground pin on the power cord of the second amp by connecting the power plug through a 3-prong to 2-prong adaptor.
Be sure to use the 3-prong plug on the first amp.It will supply a common ground for both amps. |

| Jim and John, thanks for your advise. Using a 2 prong adaptor on the second amp did eliminate the hum problem. Appreciate your input. |
