Electro Harmonix Bad Stone

Disclosure, this is my first phase pedal and thus, I can't really compare it to other phase pedals.
I bought this after listening to Tame Impala, they use this effect to great effect.
It's EHX so it's neat and feels solid and weighty. I like that it comes with a battery and can be driven by one. The sound is very nice and adds a nice warmth to my strat. I feel like this is a always on pedal. I've set my feedback and rate knobs at about 9 o'clock adding a bit of movement to my sound.
