Nothing electric - i.e. that plays through an - amp except electric basses if the player can control his impulses with regard to the volume knob, and by all means, a pedal steel - I Love 'Em - if the player has a realistic idea of what kinds of stuff one sounds good on and can control his impulses with regard to the volume knob.

No shaky eggs.

No washboards unless the owner can limit his playing to zydeco, ragtime and jug band numbers if anyone does one.

No "stomp boards."

And no G**forsaken, Jeezly, f***ing, never-to-be-sufficiently-damned Spoons!

Peter. (Yes, these are my particular personal prejudices - but I cherish them.)
