I agree if it sounds right to you then you dont need to worry about clock rate accuracy. It should also be pretty noticable if its clipping. But if you do need to adjust, and feel you need the tools to get it right then a multimeter is no good. Nor is an audio rate scope-realistically these are pretty poor for electrical use, although great to understand how you are manipulating your audio.

If you can borrow a scope from anybody you will almost certainly not need a freq counter as it will probably be built into the scope.
