I bought the M68 mainly to try to get the 'Leslie' effect, which, with careful setting of the Rate function, it will do. Although I'm still undecided whether that sounds best in Vibrato or Chorus modes! Where I struggle a little with this pedal is getting a good overall 'washy' chorus sound. Pulling back on the Level control will only reduce the overall volume - what one needs to do is to be patient and set the Rate and Depth controls, with the emphasis on keeping the Depth way down. All the extreme noises are there, especially when used with a variety of overdrives or distortion effects. A slight downer (for me - I'm mainly a Fender player!) is that in any normal chorus sound setting, the treble is greatly suppressed. If you just use the Vibe setting, treble is there in abundance. As a general chorus effect, I think my old Boss CH1 does a better job, but that won't get you the Univibe Rotary type of sound. I need to spend more time on it, I agree, so my opinion will, no doubt, improve with time! I would definitely recommend one if you are prone to experimenting and also if you like wacky 70's/80's chorus-y sounds!!
