The Duende really was phenomenal. I just couldn't justify keeping it solely for a studio/practice amp. I built a Tweed Deluxe 15W clone with my dad, and decided to just keep that for super low volume gigs, since it was a combo (and sounded great). But I miss the Duende at times.
The Duende tones were great. Very Fender blackface deluxe-y clean. And a slightly more vintage sounding Shiva-esque drive channel. With the gain boost engaged, plenty of nice saturation too.
I own a Metropolis too. Totally different ballgame than the Shiva. More like a BadCat Matchless Voxy type amp. Class A tones. Squishier, chime-ier.
