+10 for the Rabid Rodent. The way it was designed from BYOC, it was 6 different stages of distortion. DVM modded it (there's a surprise ) to be 3 OD and 3 distortion stages......and then added the Ruetz mod that works on the above 6 stages. Fabulous.

If you don't need the distortion, his OD II is great for overdrive with a boost.
