Does anyone know if one of these is better than the other? The AT and Shure look to be the same... the ProCo is not switchable But it's also about $20 cheaper. I think I'd just get the 20db... they come in 10,20,& 30db. I don't think being switchable would be that important, or I should say worth $20. ???

Thanks,
B.

I'd get the AT 10/20/30 for $39. It would be handy to have all the options. And look at it this way - the first pad is $20, and you get the next two for $10 apiece. A bargain.
