I own two of these. One i keep in my effects loop to take care of the harmonies. The other i keep before the amp input for the S-bend function! This pedal does alot but those are my two favorite things. I tried the digitech whammy and it just sounded bad...plus you had to engage it to use the whammy part of it. Not with S bend function, pedal stays off until, you hit it! This preserves your tone! Plus takes up way less space on a pedalboard. As a Harmonist it is better than the whammy again! You set a key, not a just a scale thing, sounds better too! For me the digitech killed my tone.
