Here's what each item included does:

• GRAMMA sound isolation riser for combo amps reducing mechanical vibrations.
  
• Xpander™ and Tri-Xpanders™ - Isolate your microphones during the recording process to eliminate external noise bleed and filter those undesirable external overtones from drums and mic stands.
  
• MoPAD monitor isolation pads to eliminate bass coupling (reduce resonance through your mixing desk) and angle your reference monitors at your ears .
