Hi @guyl 😊
When getting surface mounted jack did the luthier need to drill anything and/or make any adjustments to the pre-amp cavity?
I am wondering doing the same with my TRBI, but for me it looks like I would need to drill and do som adjustment in the cavity to allow the jack plug to manage go straight in.
Wich model of the TRB do you have?
I know the pre-amp cavities are a bit different through the TRB-range
