M1A cable and jack
I recently bought a used M1A that didn't include the endpin jack and cable assembly. Is the correct 1/8" phone plug a TRS or TS configuration? I'm guessing that since the M1A is an active PU, the ring-sleeve might be used as a switch that is enabled by plugging in a TS cable.
Thanks and best regards,
You are correct. The harness that should have been provided with the M1A is TRS and the power switch is Ring to Sleeve.
If you purchased the pickup as new, please reply to [email protected] with your mailing address and I'll send the part.
