Jump on GRAMPS+ to daze and confuse. Which of course will make your band and audience gratefully amazed. Or use it on all guitar tracks on all your recordings for that not so shimmering, bowl movement provoking, beautiful sound.

Like the rest of the Himmelstrutz pedals GRAMPS+ will sound great at any volume. Just more wild, more fuzzy. Of course its also capable of generating lovely musical distortion sounds which will transform your sleepy, boring life into a creamy, distorted, versatile mess.

Even though GRAMPS+ sounds great by itself, used as anything from a Boost, a gentle or more driven Overdrive/Distortion or finally into a dark, addictive, provocative FUZZ* it also matches perfect with any other Himmelstrutz pedal—stacked in whatever order you prefer. 

—This sounds like visiting Hell, in Finland? Or Hell-sinki? Or Noise Hell!

—That’s a lot of questions…

—Well, in short, you mean this pedal includes a noise gate?

—No, as the Himmelstrutz’ pedals don’t generate much unwanted noise.

* GRAMPS+ will never get way-out-of-control (weird gating/sick octaves/oscillating etc)—at least not when played by itself.
