Hello Randy, Some metrinomes have a feature that produces a pure A 440. (Other metrinomes, fancy ones, can produce all twelve chromatic notes, but these are more expensive.) You could use this to tune your A string (two octaves lower,) and then tune the other strings in relationship to that A. This still doesn't tell you if your A is sharp or flat with respect to the A from the metrinome, but it gives you a starting place without needing a piano or synthesizer nearby to compare to. Does this help at all or am I missing the point of your question?
