I just took delivery on a Fryette Power Station and my initial impressions are quite positive. One of the reasons I bought it was to use with my Rivera Knucklehead Reverb. It's a great amp with a fantastic clean channel but the gain channels don't sound great with the master volumes below 3 and 3 is way too loud for apartment playing. Below 3 the mids sound somewhat congested and the highs are attenuated. Enter the Power Station. First thing I noticed is this thing is built like a tank. It feels industrial strength coming out of the box. Secondly, it was a snap to set up. Two minutes reading the manual and I had it fully wired three minutes later. I hooked it up to the Rivera and my Deliverance 4x12 stack with the Rivera's master volumes on 5 and both of the Power Station's voicing options set on "Flat" and slowly turned up the volume on the Power Station. The resulting tones were the best gain tones I've ever heard come from the KHR. Both gain channels opened up substantially and had more detail than I'd ever heard come from that amp. For its use with the Rivera alone it was well worth the purchase price. I plan to try it with my Sig:X, Fender combos, Quilter MicroPro, and even the Axe FX. This thing has so many potential uses. Clearly I'm still in the honeymoon phase since I've only had it for little over an hour, but my immediate impression is that this is one stellar piece of kit. Steven Fryette has done it again with a unique product that delivers the goods big time. Congrats and thanks Mr. F for a job very well done.
