I probably have been using this pedal since 1982. I found this one capable of producing very smooth, creamy & clicky sound. This really puts life especially to clean tones. However it is also very effective to be used with distortion and overdrive effects. I found its sound very rich, warm and full. I have used it with both humbucking & single coil pickups and found extremely effective. I mostly use its settings in this manner; Level set in between 2 to 3 o'clock & Sensitivity set at 3 o'clock. Works extremely well with chorus & phaser effects. I like its extremely low power consumption which is only 1 mA thats why it never bother me to use the A/C adapter even with regular use. One battery last for many months, Great indeed. I wish it would have a Tone control as well but it is not necessary. For clean tones I will give it 5 marks all the way because with overdrive it is somewhat noisey but can be tackled with tweaking with amp equalization.
