From the post

An out of production EQD overdrive that's based on the Distortion+. From the source:

The White Light Overdrive is based on vintage overdrives that defined the sounds of classic hard rock. This vintage voiced stompbox is similar to a vintage DOD 250 or MXR Distortion+, but don’t mistake it for a direct clone of these OD’s of yesteryear. The White Light gives total control over the voice of the dirt along with a modern presence that is both dynamic and responsive to your playing. The Weight control allows you to adjust the saturation and low end, giving you plenty of tonal shaping options. The White Light Overdrive doesn’t discriminate – it likes both humbuckers and single coils, and will add some real 70′s grit to your tone. The Compression switch lets you choose between an open voiced overdrive with more high-mids and bite, or more compression with less bit and flatter mid-range. Controls Gain: Controls the amount of distortion. Weight: A multi-functional control, allows the level of saturation, bass response and the over all feel of the device to be altered. Level: Controls the output. Compression Switch: Less= Open w/ more high-mids and bite. More= Crunchy and compressed with a bit less bite and more flat mids.
