I recently bought a 2001 Peavey Millennium Plus and I’m having an issue getting the neck straight. When I first purchased it the neck was perfect until I changed the strings…Now it’s all sorts of jacked up. I put the original strings back on it and I’m still not having any luck. I’ve watched a few YouTube videos of people bending the crap out of the neck without strings and all sorts of stuff. Any advice would be appreciated. Thanks.
