Hi guys, so I changed my strings today on my SR500, and one of the tuning pegs broke so i start to look for some replacement and i think the best ones I've found were the Gotoh GB707 but I'm not sure if they will fit or i should drill other holes, anyone knows? GOTOH GB707 Compact Bass Tuning Machines Tuners - Preconfigured Sets And if you know other good replacements to make the SR500 super-great let me know please. I've been thinking about changing the preamp or the pickups. Thank you very much!!!
