I have 4 Audiostorm attenuators, which I have bought over the years as Shaun Mandrake evolved his offerings, I bought this one to use on a PRS HDRX 50 watt head, as recommended by PRS per the manual. it sucks very little tone out which is good, and is a small unit. I haven't yet taken a feed for recording but that was a feature that also appealed to me.
