Hey guys, I recently acquired a used US Peavey Cirrus 5 string, and when I tried to adjust the truss rod, I realized that I don't have a tool that will work. Is there a special tool required for cirruses? I have the T-topped metal rod used to adjust Fenders that works on most of my other basses, but the truss rod in the Peavey is mounted too far back in the hole under the truss rod cover. I can't get the truss rod tool into the hole. I tried an allen wrench, but the groove that the truss rod is in is too narrow to allow for any more than about a 1/32 of a turn of the wrench, and then you can't get it back in to turn it any further. Is there a special tool that I'm missing? Thanks!
