A couple of personal notes and observations...
I struggled with a few drive models, like Zen Master and others, until I bumped the drive block's output level. Slamming the amp's input really works well with some types.
Content on the web has exploded. It's getting harder to sift through all information. But JHS Pedals and Wampler Pedals keep delivering useful info.
Some of the newer drives are really worth checking, but use them in the right context. For example, the OD 250 and Hoodoo Drive sound excellent but only when paired with a vintage dirty amp (Plexi).
There's a lot to choose from now in the "natural overdrive" section, and in the amp-in-a-box category.
I would gladly post a list of my favorites but that would cover most models. I kinda like them all. Except Master Fuzz, TS9DX Hot and Plus, Shed, Metal Zone.
Enjoy the guide. And don't overlook the demo presets (use a Strat or Tele, or low output humbuckers).
