Product Description
The Mojo Hand Fx Magpie is a transparent overdrive designed for the player that wants that little something extra while still maintaining the character of their guitar and amp. The Magpie features a 3 way toggle for different clipping options. The Up position is the “Crunch” setting. It features more compression and a dirtier overall tone than the bottom two positions. It’s great for low to medium gain sounds. The Middle position is the “Boost” setting.
It removes diodes from the clipping section allowing for a nice signal boost that’s great for pushing the front end of your favorite tube amp. The Down position is the “Overdrive” setting. It provides low gain sweetness with just a touch of edge.
Features Include:
Full Range Tone Control
3 Selectable Clipping Options
True Bypass Switching
Die-cast Enclosure
UV printed artwork (more durable than screen printing)
