This is a great little tremolo pedal and has more than enough range in its speed control to fit any circumstance. I've read online that some people question if the largest knob would have been better given to adjust 'speed' rather than 'depth' and maybe I too would agree with this, although it doesn't really ruin anything for me. The addition of a volume control is very useful to combat any perceived volume drop -a typical problem with this type of effect. The wave can be adjusted from triangle to square wave, although I prefer the more organic sweep of 'triangle' for a more vintage type of tone. I like this series of mini pedals in general as they are all very small -yet heavy and robust, well built and thought out. I'm not a fan of the LED that Ibanez use though as at some angles it's hard to see if the pedal is on or not. Overall, I'm very happy with this product's sound, quality and price. The chorus pedal in this range is excellent too.
