Compressor pedal vs Maxon OD808 to thicken up the tone

[Dave Sloven]

+1 on the Custom Badass

I traded my OD9 to a friend after I discovered that.  Now he is the one dealing with its horrid silent switch

Mesa Boogie Gridslammer - Slightly darker edge to it, but extremely tight and musical. Will let more of the natural sound of the amp come through. My favorite pedal to use in front of brighter amps.

I must say that Mesa sounds really impressive! I`m totally torn between Mesa and Spark Booster now. Whatever pedal I will choose. I want it to stay on all the time on both clean and dirty channel. On cleans to add more  'depth' and little subtle breakup sound and overdrive to tighten everything up and add some little gain.
