Boss Joel's gears... Baby G Power Amp, iPod LOD to RCA, and JD Labs V3 Tube Buffer...
Night Shot...
The Tube Buffer may not look like much as compared to it's good looking commercial counterparts, but it sure does it's job extremely well, like what a real vacuum tube buffer should be. With a 470K input impedance, high enough for all available signal sources and an output impedance better than < 200 ohms.
