The B,I,S Box Earth Loop Hum Eliminator is used for removing unwanted 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 noise picked up by your guitar).

The B.I.S Box is used for:​​​​​​​

- Eliminating earth loop ground hum
- Buffering guitar signal
- Driving long signal leads
- Designed and hand built by Mike Hill Services
- The B.I.S. box is also NOT sensitive to hum fields, i.e. power transformers in guitar amps.
