Just nabbed me one off the evilbay for 132 shipped. Anyhow I found out its the first generation which means it lacks the toggle switch, boosts the volume, and engaging the effect might result in the slight pop. The later two issues, if you can call them that, don't bother me, but I am curious about the lack of a toggle switch for the modulation speed. Does this mean my version can't achieve the same modulation rates as the newer ones?
