Boss made a famous pedal called the Slow Gear in the 80s that offered an auto-swell effect, similar to a violin's longer attack. They go for a fortune now, and why they haven't been reissued is a anyone's guess. Behringer were (are?) in the biz of doing remarkably accurate copies of other pedal's original designs, so this was a direct rip off of the Slow Gear. Ironically this one is also discontinued now and sells for heaps more than they went for brand new. All that aside: this is a great effect, it really does sound awesome. Pair it with a huge, self indulgent reverb and maybe a whisker of modulation, and you can fire your keyboard player; the pads are all you now. Just to clarify, the correct pronunciation of the model name: slooooooow mooooootioooooon.
