Additional Info
*Due to the design of this vintage Treble Booster circuit, these pedals work best placed first in your signal chain. These units do not work well with buffers or buffered bypass pedals going into the input of the booster. This will cause the boost to sound thin with a significant volume drop*
**These effects can be powered by 9v battery (included) or with a standard Boss/One Spot style negative center 9v power supply**
***Please note that these pedals will not work in a power daisy chain with other pedals that use a negative center power supply. It will need its own isolated power source, either it’s own separate power adapter or it works well with a Voodoo Labs or similar power brick***
