I had a problem with the tone control pot in my Essence 4 string. This bass has Europa electronics, and I never had an issue with it until recently. I had a guitar tech in Fayetteville, NC to replace the tone pot several weeks ago.
It has an assembly of 3 position EQ switches, and (1) volume, (1) balance, (1) tone control knobs. The trebel switch in the EQ assembly doesn't work now after his repair.... hello....
Can anyone suggest a competent repair tech close to Fayetteville, NC or Raleigh, NC???
Or even better.... tell me what to look for and I'll do the repair myself.
