Remember that they're also coming out with a unit called the ISO-5.
I'm definitely going to check out the size of the Versa.
This past weekend I hooked up two 1-Spot units with the L6 adaptors, along with a NASA-trained electrician standing by to check for any weirdness: none. This whole wart business has become tiresome. I hope that the brain trust here at E-Tide has seen that this thread is one of the fastest growing, most passionately debated ones.
BTW: I used the MF & TF in the studio this past weekend and live: I could not have been happier with the truly rich sound of them.
