Lotus Pedals Desire BoostAs the name says, this is a boost pedal, but not your typical clean boost. This pedal does add some "grit" to your sound without actually changing the quality of the tone by utilizing a JFET gain stage. It also has a very high input impedance designed to act as a buffer, it can eliminate unwanted noise from your cables or pick ups and pull every ounce of your desired tone out. Specifications Operates on 9VDC. Both battery and DC jack (center negative)
