I bought this pedal (used, like new) and i was intent on finding a good classic Jerry envelope filter sound (listen to Estimated Prophet) and this pedal does the job, but half assed.

The only good setting is the first envelope filter setting (second is alright but overall, not worth using) every other setting is horrible and digitech should be ashamed at themselves for marketing this product. But the envelope setting is very digital sounding, very un-organic, its hard to explain.. theres hardly a purpose for the range knob, anything over 9 o'clock is screechy highs...useless...the control helps with the sensitivity knob (once again, anything over 12-1 o'clock...useless) but i usually use an overdrive (TS9) and a slight gain boost (mxr) for a dirty sound with the guitar volume at 7 for rythem and 10 for solo's....the volume of other pedals greatly affect how this pedal will sound.

Overall, if you want the melodic tone of the Mu Tron like Jerry Garcia had on various songs, SAVE your money and fuckin BUY the mu tron.. or at least dont buy any envelope filter pedal under $200 because the envelope pedal is one of a kind and well worth the money for the tone and sound, and once you realize that you'll understand why you shouldn't waste your money on pedals like these. Your sooo much better off saving up as long as you need to, to buy a *good* envelope filter pedal. (check out the Emma pedal or Mu Tron III)

If you like making weird techno/rediculously distorted noises to entertain yourself and would never be useful in a real song that people would enjoy listening to, this may be the pedal for u!

Ik, I buy this, take it home and love it. I play it for two days and the sound blows my mind. It sounds just like late 70s Jerry Garcia. Then, the third day, I'm practicing for an upcoming gig( 2 days away)then the pedal just stops working. It goes crazy, the light turns on and off or just on, or just off. I try everthing to fix it nothing works. I have to return it, now I have no idea what im going to do for the gig I have in a DAY!!

This pedal is unique. The sounds are cool. I like the color too. It is a great pedal just to experiment with and mess around. Same with any pedal; get a power adapter. The batteries don't last very long. I recommend this pedal to anyone who likes to make unique crazy sounds.

I bought this unit after returning an Electro Harmonix Micro Synth. The SXW Synth Wah performs the same functions as the EH device, but for one third the price. As with many Digitech effects, you will need some outboard equalization to reduce the tininess of the processed sound but it does what it says it will do and the controls are direct and easy to master. As far as producing "synth" voices, if you are expecting to make your guitar sound like a fat old analog Mini-Moog, forget it. This is an envelope filter with an adjustable sweep rate, nothing more. The "synth" voices are just distortion. BTW- I am using this pedal along with a Line 6 MM4, DL4, Electro Harmonix POG, Digitech Weapon, a Boss DC-2 and a Dunlop JH-1 Wah pedal through a Marshall 3310 stack.

I have hads this unit for a while, I got when I wanted to refind a good envelope filter sound like the old days. I have gone though all the settings many times and I came back to the standard model 1 using Type 1 Sens: 9:00, Control: 10:00, Range: 12:30, this is polyphonic and gives a great heavy vocal wah sound on single or humbuckler, it can sound like Trower's My Love or anything you can dream up. Great Pedal to experiment with or use as a stable well defined and repeatable filter effect. Digitech has superior sound if you just learn to tweak and can play with some finese.
