Hi. I'm new here in this site and still not familiar on how to post a question. By the way, I own an Ibanez Prestige SRG 2520 for 2 years now. Last week, I noticed that ALL positions of the 5-way switch were giving me hard time engaging my 2 installed SD humbucker pickups. I would just like to ask, If I were to replace the existing 5-way switch, What particular Brand and Model of 5-way switch selector should be appropriate with my SRG 2520? I had been hearing the Cor-Tek 2502N or Cor-Tek 5202N. Can I ask your expert advise on this matter? What are my other options in terms of the other brands in the market? Thank you.
