Here is a dumb question i have about changing strings, I just changed my strings on my SADOWSKY and this is like the 3rd time i change them. What i do is i take out for instance the 5th string clean that area and immediately replace it with the new string. I do this to each string, so here is my question, is it ok to do it this way? or can i just take off ALL the strings at the same time and then clean and re-insert with new strings? I am afraid if i take off all the strings at once it may not be good for the truss rod, again its probably a dumb question but i would like to know the answer...Thanks in advance.
