This Carvin CT6M-DTS has an M-bridge and the pickups and electronics have been replaced. It has Re-Wind True Kalamazoo pickups ($400) and CTS pots, etc. The action is super low on this guitar and it plays really well. The 3 step process of the Deep Triple Step process from Carvin leaves this guitar with a beautiful top. It has an ebony fingerboard and locking Sperzel tuners.It has some very light playwear but is in super condition.
