I'm currently using a Hardwire Tube OD pedal as my main OD. While I like it for what it is, it often is not crunchy enough to stand out in a mix with crunchy guitars. I have a parallel wet/dry set up via my amp, so I am open to any guitar or bass OD pedal, no blend necessary. An old Marshall Guv'nor is at the top of my list, but I'm interested to see what TBers are into right now as far as crunchy OD.
