From the vendor
Lemmy.
Iconic in every way.
We can't give you the attitude and good looks, but we can give you a box of badass that'll help you get that signature sound.
Tight and aggressive, with enough clarity to take the lead in any mix. An internal charge pump gets you around 20V of headroom from your 9V supply. Nice.
Sounds great on guitar too - honest!
