I was playing with my 5F11 I built and had the tremolo jacked way up - speed & depth. While it was up there at hummingbird heartbeat levels, I kicked on my Flanger and started tweaking it. In the end, I actually came up with a pretty cool Leslie effect. Not spot on, but pretty close considering what I was working with. I only tried it with the Tele, but I imagine the Les Paul would come closer with some overdrive just because the Tele still had more distinction in the twang & notes. Anyway, it sounded pretty cool and thought I'd pass it along.
