The Good: This thing sounds great! Found "my sound" literally within minutes. The Morph knob allows you to dial in different distortion sounds, so you don't need to buy every pedal under the sun to change your distortion sound. The Tone knob works just like the filter knob on the RAT, allowing you to roll off the highs til you get your sound, and boost slightly for cut thru a live mix. The Blend control works perfectly, much better than the MXR blend which is touchy due to the channel volume interplay and onboard tone controls. Very quiet in bypass mode, and sounds like a true bypass. Very easy to use. It's very cool that a manufacturer finally implemented the concept of pre- and post-distortion EQ into a single knob. Between the Morph knob and the Tone, I didn't even need my EQ pedal with this distortion. The Bad: The low end gets goofy at the extreme fuzz settings. It's there but just goofy sounding due to the EQ contour of the Morph. Because it's digital, there's no adjustment like gain or drive. It doesn't sound that gainy, and it can't do screamy feedback type distortion like a RAT or a Big Muff. Medium overdrive sounds are ok, but it can't do mild overdrive sounds very well - they just sound like a digital fart. The Ugly: It's MICROPHONIC. Which makes no sense for a digital device! I had it onstage next to the drum kit. With the effect engaged while not playing, the signal lights on my power amp were chugging from the drums! Last, but far from least, this thing is built like an EGGSHELL. The power connector is flaky. I first noticed this at home when I removed the battery and connected it up to my power supply, there seemed to be some glitchiness to the sound when using the power connector. And it doesn't sound exactly the same with a power cord as it does with a battery. When I got it on a stage with a drummer, my signal kept cutting in and out, and intermittently dropping and restoring level. I've never had these problems before with any pedal from any manufacturer. I give this pedal a ZERO for reliability because it couldn't even get through one practice. I could only recommend this pedal for home studio use at low volume without a live drummer. Or even better - they should just make it a plugin for digital recording. It is not stageworthy.
