3 Methods To Accurate Metal Riffing

I can only say to do it. Best thing I've done in a long time.

After a year with Karri there is a huge difference in what I can play.

One thing Karri is especially good at is teaching alternate picking and down picking; how to break through plateaus and play really fast with good tone and consistent timing. Strongly recommend working with Karri and also practicing a lot. If you combine these two it's impossible to not get a lot better.

I was watching other lesson videos online and never really got anywhere. I was playing for hours and hours huting my picking hand while doing that. Eventually I found Karri and reached out and started working with him. We have been working for 6 months together and my skills have gotten so much better. My speed is way up and we have solved a lot of problems in my playing.

Prior to learning from Karri, I had been playing for a few years but my technique had plateaued. This got frustrating, especially if you love metal the way that I do. I started Googling for techniques to help, tried a few and never really got anywhere, then ultimately found Karri's YouTube channel and started working with him. This has been one of the good decisions I've made in my life as my playing has materially improved since.

I’m a former guitarist of Scar Symmetry and a professional musician since 18.

Before working with Karri, my technique was a mess—my hands and shoulder hurt when playing fast, and YouTube tutorials weren’t helping. Karri showed me what I was doing wrong, fixed my technique, and gave me a real practice routine.

Now I play faster, more synchronized, and pain-free. In three months, I’ve learned more than in the last 20 years. If you want real progress, I highly recommend working with Karri!

I’ve been taking lessons with Karri for over a year. Before that, I was stuck—I’d learn riffs here and there but never made real progress.

That changed when I found Karri on YouTube. He didn’t just teach me techniques—he helped me break through plateaus I thought I’d never overcome. My alternate picking, down picking, and speed have improved massively, and I finally have a solid technical foundation.

Karri’s ear is incredible—he catches the smallest mistakes, even over Skype. He tailors lessons to what I want to play, making practice both fun and effective. If you put in the work, it’s impossible not to improve with him. Highly recommend!

Before taking lessons with Karri, I struggled to play the extreme music I wanted.

After winning a free lesson on his YouTube channel, I quickly saw how much he could teach me. He helped me set clear goals, improve my technique, and understand music theory and composition—things I had never worked on before.

Karri knows exactly what students need (and don’t need) to progress. His lessons aren’t just about guitar but about music as a whole. Highly recommend!
