Grindstein – The ultimate death metal preamp

Unverified overall ratings (5 customer reviews)


Metal producer Kristian Kohle (Aborted, Benighted, Powerwolf, Hämatom, Eskimo Callboy) and KLIRRTON have teamed up for this dirty beast!

We are taking the dirty and fuzzy death metal tones from the 90s into the modern age. You can go anywhere from a ripping chainsaw to a more modern and tight sound with just a touch of grind. It can go from the Swedish HM2 sound all the way to 90’s Florida transistor distortion, but with modern fat lowend and thightness like never heard before! A character beast with many dirty sonic possibilities! The ultimate combination of old school and modern! The pedal is intended to be played straight into the poweramp of a tubeamp with a cranked presence! (You can use it in front of an amp as well, but it’s not gonna produce the sound from our demovideos.)

Plug and Play recording device and livesound:
There’s Kemper profiles and IRs of different poweramps and cabs included. All recorded at Kohlekeller Studios. Using these profiles or IRs you can plug the Grindstein straight into your soundcard. So it’s plug and play even without a real amp both live and in the studio!

Effectloop to mix ANY sound with the chainsaw channel:
There’s an effectloop that gives you the possibility to mix YOUR favourite distortion pedal or tube preamp with the chainsaw channel of the Grindstein and there’s a phase switch for sonic experiments. Endless possibilities! So if you’re looking for something more dirty and charismatic than your everyday modern high gain, this is for you!

BUT BEWARE! The GRINDSTEIN is ugly and fuckin dirty!

    I own this pedal and love it. The Bottom Shaker channel (Mix knob full CCW) utilizes the lower Gain, Treble and Bass is really good on it’s own as I cannot get that sound with any of my other pedals; really nice singing lead tones. The Chainsaw channel (Mix knob full CW) is very aggressive and plays well with the Bottom Shaker. You can also use the effects loops to substitute the Bottom Shaker Channel with any pedal, even another HM-2 clone if you wish 🙂 The boost works well, the phase switch creates really nice tonal options, and the Master has plenty of volume on tap. All in all, a really cool pedal that allows you to mix in different flavors with the Chainsaw channel. I run this into my UA Apollo and use the amp sims, i.e. ENGL, etc., with the preamp section turned off.

    It does everything it claims and more. My neighbors love my brootal chainsaw tone and girls have found me much more handsome! All kidding aside, it’s such an amazing pedal and I’m so glad I own it! Built like a tank and I just can’t stop tweaking it because it has so many useable sounds. I ordered my own Klirrton Oh My Goat 🐐pedal tonight and I couldn’t be more thrilled. I am huge fan of all this company does and they have the best customer service ever 🤘🏼 Thank you Klirrton!
