Paired with the PF R, the Prestige series solved all the noise and loss of bass response issues with my Mesa Boogie F-30. The tube amp now sounds better than new and the effects loop and buffer send/receive pedals can do their job to retain the sparkling highs and responsive pick sounds the way they should. The P-1800 AC R provides up to 15A of noise free AC power but keep in mind the nominal current draw of the unit and the other Furman power conditioners reduce your headroom by about 10%.
