I recently bought a used albert lee had it a week /love this guitar. It was posted from a cooler climate state so perhaps the hotter climate where I live has caused neck to change.The tuning went out and when I tried to tune it I had buzzing at fifth fret E bass and it just sounded flat on all strings.Looking along neck it has bowed back this was a surprise as I didnt expect this to happen,so as it needs readjusting to get it straight again is this a case of turning the truss rod clockwise till it gets back to a straighter position?.I have not done a set up or neck adjustment before.
