Here's the second of my reviews. This time we'll discuss the Deluxe Electric Mistress. Size This pedal is very large. It is approx. 8"x6" Power: I have a mid-90s unit that has an attached power cord. I believe the newer versions have an adapter, but I cannot confirm that. Bypass and Tone Suck It is not true bypass. It has a slight loss of low end when engaged. It adds a small bit of noise when the color knob is increased as well as going into Filter Matrix Mode. LED: No LED. You have no way of knowing it's on unless you're paying attention to the sound. Controls 3 knobs, 1 switch. The knobs are: Color, Range and Rate. The switch is for Filter Matrix The Color knob adds a sort of trebly sound and makes the high end stand out a bit more. I'm not actually sure of what it does technically. The Range knob allows you to set the lower limit of the sweep. The Rate knob controls how fast the sweep is. Sound: The effect is very subtle through my practice amp here at the dorm. Through my GK rig it is more pronounced. It seems to respond best when my pickups are fully open. I've recorded 3 samples on my sound click page which you can find here The Flanger clip is a sort of Tool-esque riff/ripoff in D minor. Its played with a pick and gives you an idea for the extent of the flange. I had to remove some noise from this track. For some reason, the pedal was incredibly noisy when plugged into my sound card. The Filter Matrix clips shows off the metallic sounds possible in filter matrix. Then I play some chords and manually sweep using the depth knob. The Filter Matrix mode takes out the rate control. The 3rd clip is Flanger+Big Muff for some EVH style sort of sound. I really had no idea what to play, so take it with a grain of salt. You can hear a lot of the noise from the pedal in this clip. This noise actually does not come out of the amp whenever I'm playing. I'm not sure why it was there. My dorm room does however pick up a lot of radio interference. My Opinion: It's a very subtle flanger that does the "jetplane swoosh" if you play with hard dynamics at a higher volume. Without your pickups on full and playing moderately loud, I think the effect is kind of lost. It can also do near-chorus sounds which is pretty cool. The noise is tolerable, when you do hear it. Filter Matrix mode is great for ambient noise fests. You can ever make the metallic overtone out of tune with the fundamental you're playing. One again, I'm open to any questions or criticisms. Hope this helps.
