Our Ultra series cases are identical to our standard cases except they have TEMPERATURE control that gently and slowly warms the instrument up to ideal playing temperature. No worries about blowing warm air into a cold instrument! Since the pitch is already up to playing level, no warm up is needed. The case is plugged into a standard wall outlet in your home or studio any time the temperature is below approximately 74 degrees. Over a period of several hours the case will warm the instruments up to playing temperature which is between 78-84 degrees.
Unplug the cord, place the cord in the zipper packet on top of the cover and go to the rehearsal or performance. The case will keep the instrument in playing temperature for several hours before needing to be plugged in once more. ALL Ultra
cases come with a SPECIAL HEATED CASE COVER as part of the Ultra system.
