Small Stone : it's a phaser

Pretty simple to operate - just one knob for the speed of the phase and a switch to change between two modes. When the switch is in the down position the effect of the pedal can barely be heard. It's subtle and discrete. When in the upper position the effect is much more pronounced, but the original signal of the guitar is a bit lost which I didn't like. I believe it's quite good for a phaser, but after some experimenting with various phaser pedals I discovered that I just don't know what to do with a phaser so I don't use them anymore.

With this one, I experienced a sudden drops of volume a few times, only for a split second - probably a cold solder joint somewhere.

I didn't open this one, so I can't tell for sure, but despite the fact that all EHX pedals have "Made in NY city USA" written on the outside, inside I found "Made in China" claim. It doesn't make any difference to me, but some people might want to know.
