Not only is Denny a world-class musician, he’s also a professional guitar builder.  These full length feature videos will show you all of the little secrets Denny’s learned from working on guitars over 60 years. You’ll learn things like…

  • How to restring your guitar the professional way (acoustic & electric)
  • How to fine tune your guitar the professional way (acoustic & electric)
  • In depth discussion on strings (when to change, shelf life, what to buy)
  • Simple things that you can do to make your guitar play significantly easier
  • What to look for when purchasing a new or used guitar and how NOT to get taken
  • In depth discussion of the Zager String Science and how to make your guitar play 50% easier

This additional expertise will save you countless hours of frustration, and possibly a damaged instrument. It’s virtually impossible to place a dollar value on what this amount of information is worth simply because so few people have it.  Denny will be adding new guitar tuning & adjustment videos to his online video library all year long.

Ongoing New Lessons, Videos, Tabs & Arrangements


Denny’s always working on new material for his library. Continue to look for new lessons, arrangements, videos, as well as new instruction techniques throughout the year. It’s for this reason the majority of Denny’s students have lifetime memberships.

100% Money Back Guarantee & Lifetime Warranty

graphic_seal_b.gifIf you would like to try the Zager Library Denny insists that you do so entirely at his risk. That’s why he offers a true no risk 100% unconditional money-back guarantee.

Unlike a lot of guitar websites who are trying to make a quick buck, Denny’s program is different for one reason….he’s not in it for the money.  Denny’s already had fame and fortune many times over.

Denny simply loves music and he loves teaching others how to make music, and he wants to leave a legacy that his students can use for forever. You can see this the minute you take your first lesson with him.

Go try all the other guitar courses and compare, but try not to get taken by the fine print offers that only provide a partial refund or worse yet no refund at all. Denny Zager has never done business this way and it’s for this reason he has one of the largest memberships on the world wide web.

Download and print all the manuals, tabs and arrangements (those are yours to keep forever) and use the videos for as long as you like. If for any reason you aren’t completely satisfied simply let us know and we’ll refund 100% of your payment no questions asked. In this way you have absolutely nothing to lose and everything to gain. Denny would have it no other way.

6 Reasons to Try Zager

Learn from a Master
9 out of 10 guitar instructors have less than 5 years of experience. Most people fail at guitar not because of their inability to learn, it’s because their instructor has no real experience. Denny Zager has devoted his life to the guitar, playing, performing, building, and teaching thousands of people how to play over 60 years.

Save Money
The average guitar lesson these days is $40 per hour. When you enter Denny’s Library you’ll have access to 100’s of hours of one-on-one instruction from a 70 year Master player. This would cost thousands at the music store (if they even offered it) and tens of thousands in Denny’s private studio.  Unlimited access to Denny’s entire library costs only $8 a month.

Save Time
Why waste time and energy driving to a music store when you can learn whenever you want, wherever you want and download everything you need instantly from any computer.

No Pressure
Have you felt overwhelmed after paying $40, $50 or even $75 for a lesson with a pro instructor who threw so much information at you that you wished you could rewind everything and play it again?   You can replay Denny’s lessons as many times as you like at no additional charge.

Yours Forever
Denny’s 70 years of work including all manuals, tabs, arrangements and lessons are yours to keep forever. This means you can pass them onto your children to use for generations to come.

No Risk
When you enter Denny’s Library, if for any reason you’re not completely satisfied you’ll receive a 100% refund.  We’re a 47 year old family owned company who treats our customers like family so if you’re not happy you get your money back…no questions asked.
