I did seek out, buy and continue to use a BossR-20 because of it's features and sound. This in no way indicates a wane in my appreciation for the Cool-Cat. I just wanted the speed switch among other features.

Sound
I've owned this peal for a good four years now. I loaned out a Leslie 147 that never came back, so I know what one is supposed to sound like. So when Z-Sounds says that at fast speeds it sounds like a leslie, I'm here to tell you they're selling it short. At slow speeds the only ones that come closer are the $200 plus digital Leslie models, like the Boss R-20 (which I have) and the Digitech Expresion Machine (I will be trying the Line 6 Roto-Machine soon). Don't forget; the chorus, phase shifter, and - the grandma of 'em all -the Uni-Vibe, were all invented to simulate a Leslie. They would be considered failures, save for the fact that they instead, by circumstance, brought us other cool sounds we liked, sounds that became industry standards in thier own right. If you're into the "flowery" '70's Ibanez sound - which I personally think is a little corny and dated - you might look elsewhere, but do so after looking here. Think Clapton with Blind Faith or Harrrison on "Sun King". If the Cool-Cat had a second footswitch for two speeds and a "ramping" rise and fall effect, it could compete with those above named pedals - easily. But they market it as a simple chorus, and as such it is lovely, a two knob wonder, easily competing… read more with the old blue Boss. Heavy and apparently indestructable. Never a problem, except it is an 18 volt effect, so carefull with power supplies and never leave it plugged in, as this mistake does get expensive with batteries. Also the second "stereo" output is simply a straight signal with the other side sounding like the unit used in mono. If you want pich bent on one side and straight on the other, you'll have to shell out the dough for something else. Forget stereo use (this baby sounds 3-D enough in mono). These two points bring it from a 10 to a 9, but not a smidgen lower. This is the only place the low price shows itself. Used straight in the guitar chain it's really at home, and enhances any overdrive pedal, especially following it. Fantastic all purpose chorus sound. I recomend it highly, if only for it's slowish settings, very deep, organic, cutting and creepy, usefull all over the place. Everyone should own one. You'll use it alot.

Features
One unbeatable sound, so useable in many ways is a great feature.

Ease of Use
Just two knobs, an on/off switch. Hard to find a bad sound.

Value
9 - A second footswitch for fast/slow would give it a 10...or 11!
