Earth Loop - Ground Hum Eliminator

​​​​​​​ EARTH LOOP-GROUND HUM ELIMINATOR 
​​​​​​​
The B.I.S Box Earth Loop Hum Eliminator is used for removing hum caused by earth/ground loops.  If using two amplifiers, simply connect one amp to the buffered output and the other amp to the isolated output and this will stop the hum (the B.I.S Box will only stop earth loop hum, not hum picked up by your guitar).  Used by top touring bands around the world.

The B.I.S Box is used for:​​​​​​​

• Buffering guitar signal
• Eliminating earth loop hum
• Driving long signal leads
• Designed and hand built by Mike Hill Services

Features - 9V battery operation with "4 hours to go" indicator - so you know you can finish the gig!!  The B.I.S. box is also NOT sensitive to hum fields, i.e. power transformers in guitar amps.
