The Ashdown Engineering Pro FX Pro Drive Pedal brings modern aggressive distortion to your bass tone. For those who opt for a pick over fingers or those who dig in like the greats, the Pro Drive gives you control over the amount of gain and the tone of your drive—from a dull, rumbling thunder to a screaming banshee. The Pro FX Pro Drive is constructed with a robust steel housing and an anodized front plate. It is manufactured using selected components from the best manufacturers in their respective fields, including genuine Neutrik jack sockets. The pedal must be powered from a 9V supply (available separately).
