Wow, see, I don't hear anything harsh about the BB!
What is the Rodenberg and where to get? For now I am sticking to my J&J OD!!! Killer frickin pedal!
To me the OCD is best into a clean amp, not as a lead boost.

Dan, wow, I think the 20th Shiva has too much gain for my needs. We only go as heavy as Metallica, Alice in Chains and Tool and I never take the gain past 1:00! I only am going to use the boost when I run less gain. But stock, the 20th and PWE have loads and loads of gain, more than I would need, even for thrash. Kick in the built in solo boost and it adds more gain. Don't forget the Mode switch, man...tons of gain, LOL.
So, when playing thinfs like Alice in Chains or Metallica, I use the amp's gain for everything, just kick in the solo boost for leads.
When playing something like Radio Head, Matthew Sweet or Pearl Jam, I either run my volume lower or the amp's gain lower. That is when I use a pedal for leads to add some juice, so it doesn't have to be a high gain or aggressive pedal, just add a touch of gain and mids to make the leads greasy and easier to sustain and to get rich harmonics. Xotic has been the best thus far.
