hmmm...interesting i should see this today.
pedals..man does not live by pedals alone. most of the online 'comparisons' are caca...usually because more than one variable is introduced (thass right...go back and talk to your high school algebra teacher!). for that matter, this 'pedal acts like a tube amp' bidness...well, it depends on the settings, the player, the guitar, the amp.....as to how a pedal sounds. introduce just a little change, and many pedals sound different...way different. this is why i been selling a bunch of stuff on ebay...and will sell some more. but...then...everybody's ears are different, too. remember the old school game of 'telephone'? some people don't know how to listen, or hear something different than what was said if you listen to a recording of the original statement. amazing. there are guys who CLAIM they can hear differences in a pick material, cables....yeah, yeah, yeah as the beatles said.
however, skating around mindlessly, i came across this:
http://texasbluesalley.com/oldtonezone/tone-tuesdayaccording to Will Chen's blog (frugalguitar.com, Dec. 9, 2008) (i think Will wrote that...reads like his writing) this fella compares pedals using the same amp and 'The Comparinator' (some device that is an a/b switcher, maybe?).
site was still active as of a minute ago, as i was tooling around listening. take it for what it cost ya...nothing.
