ear plugs

[Dennis Johnson]

        I'm wondering if these expensive fitted plugs really work for the
high treble and honing in solid unisons. The cheap foam ones work fine for
pitch raising and most of the tuning, but I find that it is impossible to
finely polish solid unisons or tune the high treble with them. John, have
you also tried the cheap plugs and determined that yours are worth the
cost?
