  • Learn to jump freely between all fingerings, everywhere on the fretboard.
  • Build any position, "on the fly", without memorizing box shapes.
  • Spice up your playing by learning new creative improvisation ideas.
  • Expand your improvisation skills, and learn how to navigate the fretboard freely and creatively.
  • Lifetime Access (including future updates) on all your devices.


"When I first tried out Prokopis' system, to my amazement I 'immediately' began to map out the scale sequences with SFS. Prokopis is certainly a talented musician and teacher.”

Karl Sartin

“The very visual approach of SFS has already unlocked my mind to the fretboard. Having bought many many books and videos etc, I can safely say this is the very best system for me.”

I am a music geek fascinated with learning new things, and improving my guitar skills. But I'm also very passionate about helping others do the same!

After studying in the Greek National Conservatory, and Berklee College of Music, I began performing and teaching privately in 2001.

Since then, I have been developing new methods for effective musical training. My mission with String Systems is to share them with the world :-)

“…When I first watched a few of your videos, I instantly knew there was something different about this system. I cannot believe all guitar players are not taught this way. It’s so simple and it makes sense so quickly.”
