I don't know about Lightbender but the Hyperdyne counter is 2"x2.5" and the soundboard is 1.5"x2". I was once the proud owner of an older model Spulse, so I'm well aware that I'll have to do some carving to make it fit. I was hoping some folks here might have tried it themselves and could share some helpful info on where/how they went about it.
Thanks for your input, Spat. I look forward to ordering one of your shiny new Spulse kits in the near future.

*edit* After checking up on it, I think I'd rather go with a Lightbender counter. It's smaller than Hyperdyne's.
