Yes, a tube amp still injects those gentle overtones that make a synth feel alive. The distortion is natural, not a hiss you tune away, and it rounds off the high frequencies nicely. But if you’re chasing absolute clarity, you’ll need to match the amp’s gain carefully—too much gain and the synth’s nuances get buried. In short, a tube can revive a synth, but only if you treat it like a component, not a crutch.
