got myself an MXR ZW-44 Zakk Wylde Overdrive last week.
nice little devil i have here. gives me a marshall tone whatever amp i use. it's a bit dirtier than my Boss OD-3, but i don't have any qualms about it.
so, what's the difference between the OD3 and the ZW-44?
the OD3 is a very transparent OD that kicks my clean channel dirty without messing with my amp's/distortion pedal's sound. it's great for blues and jazz, but it kinda lacks a bit of teeth for heavier songs (e.i. SPF, Song4, Hemlock..).
now, the ZW-44 is a monster on its own. it sounds very similar to a marshall shredmaster distortion pedal with a low gain setting or with your guitar's volume knob rollede down (but your shredmaster's gain setting up full). you can barely hear the difference between the two. in fact, in the last MaHaSa band practice, i kept on using the ZW-44 as my main dirt pedal and just used the shredmaster for boosts - and the boys didn't even notice. oh yeah, did i already say that it makes you sound like you're using a cranked-up marshall plexi? combined with the Marshall Shredmaster, this set-up makes you sound like you're using a cranked-up marshall JCM.
i don't play metal, but the ZW-44 makes a good boost and od pedal for our songs - which mostly boarders on classic rock - blues - prog.
