Online Guitar Classes (Students) / Boss Katana Presets

Keith Shelley

“I came across Juca after I had purchased a Katana amplifier and was looking for community tone presets to see what the amp could do. Juca’s tones were far superior to anyone else in the community (dead on, every time) and I started following his posts. Little did I know just how prolific and knowledgeable he is about all things guitar and recording.

I have learned more about equalization and how to methodically dial in a great guitar tone for any situation from Juca’s YouTube tutorial series than I learned in an entire year of recording classes in college. He takes a tricky subject and walks you through it in a way that not only makes sense but gets you excited to start experimenting on your own.

Juca has also cultivated a fun, supportive, inclusive online community of guitarists (no easy task). His Facebook group has quickly become my favorite place online and I find myself constantly inspired and motivated by the group and Juca himself to keep learning and have more fun playing guitar!”

Shout out to Juca Nery Campos ! I’m learning so much from my guitar lessons with Juca done over Skype! He’s great at explaining everything, a good teacher!

I played guitar when I was younger but never knew much about theory or techniques. I was “self taught” (meaning I could read tablature).

3 Lessons in with Juca and I feel like I know 10x more than what I knew before I started with him! A+++!”

“I’ve been playing guitar for over 25 years, but like many guitarists fell into a rut. I met Juca as part of a Katana group online and quickly learned he knew his stuff, from Katana to presets to tones to guitar technique and theory. I started taking lessons with him and in just a few lessons I’ve learned more than I’ve covered in years on my own. He really helped me unlock the fretboard, as well as helping explain the ins and outs of the Katana to me so quickly, saving me a bunch of time and really helping me develop as a player. Now I can concentrate on just sounding good and playing well, and people have been noticing the improvements in my playing. He takes the time to do lessons in different time zones, as well as follow up with video lessons and tabs. And the presets and bundles he offers on his sites are amazing. Can’t recommend him enough, and on top of it all he’s a really really good guy. I’m really happy I met him.”
