This is the first time I've been able to find a headphone practice amp that has realistic sweet sounding overdrive and I've tried a few!- gorgeous! All comments about poor flimsy construction can be ignored, as long as it is used for it's intended purpose i.e. with headphones as a practice amp and not live in the stadium whilst head banging, head butting the bass player, doing Pete Townsend impersonations or allowing a roadie within 15 feet of it...
