Once again Greenchild has knocked it out of the ballpark with the Kursk. This is one powerful well built pedal that to me exceeds the “Klon type pedals”. A lot of headroom and this baby makes my strats sing. My Twin loves this pedal. My favorite of all Greenchild gear. I’m also stacking it with the Thresher which is all I need...get one!

Kursk and Klazo
Written by Mark Stanford on Mar 2nd 2019

I played guitar back in the late sixties. Yeah...I am that old. Anyway...family..job and other stuff got in the way and I stopped playing. When I retired in 2013 I had time , so the journey began again to find that certain "tone" that had been in my head all these years. All us guitarists go through this. Countless pedals and amps later, I have finally found what I was looking for. The Kursk and Klazo used in tandem are the greatest sounding pedals I have ever owned. That creamy overdrive is the most beautiful thing in the world. I am glad I found Greenchild and hope they come up with some other great pedals. If you are on the fence about trying one or both of these fine pedals, go for it! Mark - Seal Beach, CA

Little red box of EVIL

Ok, I LOVE drive pedals, I can list you about 16 of them sitting next to me now, and of those, I own: Greenchild Kursk, Greenchild Mr Boost (always on) Greenchild Klazo Greenchild Thresher Greenchild G777 (green channel is sublime) The Kursk behaves like a Klon, with the amazing added feature of having both a bass and treble knob, either can be boosted OR cut, (Which is so invaluable to me) the difference between all these flavors of drive pedals is mostly the EQ, To be able to take a fairly transparent,overdriven tone, add more jangly top end, or more sharpness and top to Metallica style metal chugging,that’s like tailoring your tone to sound like YOUR pedal,your design.. I like lots of tight,low end girth to my metal tones, the bass control lets me ease up nice low end frequencies, chosen by Mason,to be tight and huge,not muddy..he has a GREAT ear,and knows exactly what he’s doing. I don’t adore every pedal he makes, ( I’m the worlds pickiest pedal guy, I return 4-5 pedals for each one I keep) I can always spot something wrong with popular fx, I hate Phase 90’s because they leak phasey sounding artifacts when bypassed,only I seem to be able to hear this,it seems. I returned The Angry Charlie,The Friedman BE-OD, Wampler Pinnacle,Wampler Ego,TC Mimic,and countless other forgotten,expensive pedals because they screwed with my EQ or the fidelity, if I heard any tone suck or change in EQ, the pedal went back. I can wholeheartedly say,The Kursk is built like a tank, it has this cool brushed,anodized red metal enclosure, it’s tiny, but not Chinese mini pedal-cheap looking. The silent switch and strong jacks are nice,strong..top loaded jacks,so all his pedals fit side to side perfectly,saving space and looking great..little multicolored squares of primary colors,all matching. This builder was some type of Military Engineering whiz in the Navy, so I trust he takes pride in his own work,and uses military grade components where he can,with the discipline and standards of a Navy Engineer. The fact that the builder/designer/proprietor has those high, military-grade standards,and is also this real cool, musician/guitar nerd-family man, like myself.. I really like that,and trust that. I’ve gotten great tips on using his pedals from him, he is always accessible via social media to guide customers on how to use these pedals. The bass and treble knobs are SO good, it’ll be your pedal,once u start fooling w them. start at noon, then ease the treble up, find a sweet spot, repeat w bass.. I tried putting my Mr Boost in FRONT of the Kursk pedal, instead of the usual boosting-an-overdrive method, and I got this raunchy,gritty,unique kind of fuzz-overdrive.. almost Rat-like. But not really, some kind of odd clipping, like an overdrive Sunn amp, I switched back to standard configuration,because it’s cleaner,higher fidelity,but I’ll continue using that sound too, you should try it! This is my first Klone,but of all Greenchild’s overdrive’s I put this one on my board,I think the Mr Boost/Kursk combo will stay on it for a long time. online demos are very accurate, sleeper pedal,this thing should be on every board.

Klon Killer!
Written by Dale Antoniuk on Jan 14th 2019

After spending a few days with my new Kursk, I must say I am very impressed...! Low to med + gain overdrive, works well with single coils and humbuckers. Has a warm tone, never too bright or shrill sounding, very harmonic. Have been able to dial in some really good blues and classic rock sounds with my Strats, Teles and PRS. Through amps running both 6L6 tubes and EL-84s. One thing I have noticed is the volume and gain are quiet sensitive, work hand in hand togeather, and need to be adjusted as so. A slight adjustment of gain will effect your volume / output. Very impressed with the build quality, fast shipping and the hands on customer service from Mason. I've tried a lot of overdrive pedals looking for that perfect tone and drive combination, I think I found it in my new Kursk ! : )
