Can someone reffer for custom setups?

[ARCM]

I live in chino hills ca. and am looking for someone who does professional custom setups. I'm dropping a 4string ESP or Muciman bass "thinking the musicman" to Drop A tunning. Since the Nut needs to be opened up and different gauge strings used I don't just want joe shmoe doing it. I need someone who is pro at this, can someone please reffer me to someone? thanks!

PM me and I'll give you the contact info for Sammy Sanchez. He's in Glendora and is one of the best techs in the business. There are plenty of others if you're willing to drive to LA or the Valley but Sammy is second to none and fairly local...not cheap though.
