Awesome! The 6l6 version? I hope you dig it! The Stealth has some serious balls, especially at louder volumes. It's definitely a tad darker too, which I really like! It's interesting, the blue channel on the 50w was my favorite, but the red channel on the Stealth is my favorite. It's like they took everything I disliked about the red channel on the 50w, and completely improved it, whereas the blue channel on the Stealth doesn't seem to be as tight/smooth as it is on the 50w, but it feels thicker/bigger. I think that's the nature of 50w vs 100w amps in general though. My 50w recto was tighter than the 100w, but it lacked the notorious sag/bottom end that rectos are known for. Btw, the hiss these amps make drive me bonkers! I don't care about the dirt channels being hissy (that's what gate pedals are for), but I can't stand the hiss on the green channel. Gate pedals don't work, because you can hear the hiss again as soon as you start playing. So as a quick tip, I use an MXR 10 band eq in the loop and turn the gain on the pedal all the way down. This seriously kills 90% of the hiss. Just throwing that out there. Also, the green/clean channel has an insane amount of gain. To get a true clean tone, keep the gain low, and turn up the volume. A 12AU7 in V1 also takes away quite a bit of the gain as well, but It also takes it away from all channels. Anyways, enough jabberin, enjoy the amp!
