The amp is a reminder of why the EL34 push-pull circuit has remained perennially popular since the heyday of the Dynaco Stereo 70. As it happens, the Silver Luna’s rabble-rousing character sets it apart from the sometimes middle-of-the-road EL34 mold.

It took a while to figure this out. I began auditioning the Fezz with ‘Tin Tin Deo’ from a 1973 pressing of Art Pepper Meets the Rhythm Section. It sounded fleshy, with a great pace, a vivid sense of interplay between the musicians, and good color – a largely satisfying rendition.

I began to get a measure of the Silver Luna’s rather special abilities when put away the jazz LPs and switched to country. After I lowered the needle on the title track, I found myself pinned to the sofa. The familiar string, pedal steel, and piano lick sounded shockingly present, and Jones’ voice appeared above my speakers like an apparition of grief. The Silver Luna sounded like it was putting a slight emphasis on the upper bass, which made its rendering of the electric bass notes sound scary good and turned it into a propulsion engine for the track. Could the amp really sound this vivid? I listened to the track twice more; each time, my skin roiled with goosebumps.

I began to pull out more country, pop, rock, and R&B records and over the next several weeks it became clear to me that the Fezz amp was a master of making listening to the genres fun and often thrilling. Its sonic signature brought the best out of music with brash dynamic peaks, ample mid and upper bass content, and blazing rhythms.

Rhythm-wise, the Silver Luna kept things in the pocket, and its punchy, dynamic, and somewhat forward sound spiked the excitement meter, making my feet tap, my head nod, and my arms waggle. And the Polish amp showed a remarkable affinity for the human voice, which it reproduced with eerie presence.

The Fezz could also throw a soundstage as panoramic as a sunset over L.A. The backup singers and string embellishments spread nearly to the edges of my room. In the center, Ben’s voice and acoustic guitar sounded as pure as an April breeze and, again were defined by that sense of rightness and euphony that I think of as sweetness.

If you subsist on a musical diet heavy on pop, rock, country, reggae, Afropop, metal, or R&B, the Fezz amp is likely to delight you. And its price can only be considered a flat-out bargain. Wholeheartedly recommended.
