You guys are too much
You can retrofit LEDs. With the existing fingerboard you can only get amber or green LEDs. For red and now (gasp) blue, you need to replace the fingerboard. It's expensive: we're talking between $995 - $1400 depending on the particulars. We need it here for about 5-6 weeks, again, depends on the bass.
Please call me or Valentino to schedule an appointment. Sometimes we can't start for a week or two, and that will push back your delivery.
