Bought these chrome Sperzel tuners to put on a Warwick Streamer LX 6 string. Sperzel tuners fit a 7/16" tuner hole, but I also bought some aluminum inserts that allow you to use these on a bigger 9/16" hole. I have since gone back to the stock tuners. Nothing wrong with them; will come with the cardboard template for drilling. According to the Sperzel site, it's pretty easy to swap the orientation on these to 4 or 5 inline if you want. Asking $70.00 OBO shipped USPS to the CONUS please. Paypal okay. can post pics in a couple of days.
