My "Boss HR-2 Harmonist" gets the Brian May "wire choir" 3-part smart harmony...CAUTION!!!...when adding the "DOD YJM 308" it may cause multi-dimensional shifting and or time-fractures in our present 3-D reality!!
I used to own lots of boss stuff, but i eventually sold them all! i only kept my Boss ns-2, and will keep it probably forever, since i found the right way to use it (those boss bastards didn't include the correct way of using it with high gain amps in their manual!)
Boss CE-5 Chorus Ensemble. Boss NS-2 Noise Suppressor. The original analog red delay is nice too, I wish i hadn't sold that
The Super Distortion/Feedbacker (or Super Feedback/Distortion, depending on which year you buy) is quite cool. The distortion is shit, but the feedback effect is awesome.
