Emerson Custom EM-DRIVE Transparent Overdrive Pedal


The EM-Drive is a fantastic transparent overdrive that really does what it says on the tin. Hand-made in Tulsa, Oklahoma this pedal has been getting rave reviews from guys like Bryan Ewald of PRS fame. The fact that it can work as a mid-boost or mild overdrive, as well as a clean dB boost makes it incredibly versatile.

The most important thing is the fact that it doesn't colour your guitar sound at all. By keeping the gain down it can act as an always-on sweetener pedal that will just give your guitar tone that extra bite of sparkle, with a little bit more dirt and a bit more character.

By pushing the gain knob you'll get a great blues/rock tone, similar to the sound of an amp breaking up, but the best thing about the EM-drive is how well it stacks with other pedals. Especially with their very own Paramount overdrive where you can get your medium overdrive pedals to go into a really saturated lead tone.

9-18v Power Supply

The EM-Drive can be run off of 9 or 18v to change the headroom of the pedal. Running it at 9v will decrease the headroom meaning it will compress and distort at a lower volume. But using the pedal on 18v will give you a much bigger boost due to the increased headroom. More power means it won't compress as easily giving you cleaner distortion sounds.
