Game changer for learning guitar

I've been playing guitar for a few years and learning scales has been most annoying because of having to constantly look away from the neck to learn the shapes and notes. The same is true for learning tabs for songs, solos, etc... The Fret Zealot allows you to focus on the neck at all times and makes it easy to ensure you are always hitting the right notes. It's an amazing technology that will definitely help new players and skilled players alike. In addition, the LED lights look really cool 😎. It has definitely helped my playing and speed in jamming to different keys. I highly recommend.

Thanks so much for the kind words! We're hard at work on more features and content as well, so look forward to lots more to come!

Very good start

Fret Zealot is a very good learning tool in my opinion. However, in order to get the LED strip to fit my Schecter S1 custom fret board. I had a hard time getting the fret strips to fit within the actual fret spacing on my guitar and after I did and went to bend the LED strip over to attach it to the neck the difference in fret position ALMOST caused me to nearly kink the strip in several places. Thankfully I caught it before damage was done but now the strip that runs up the side of the neck is a VERY wavy line instead of a straight one which caused problems with adhesion under the strings and along the side strip as well as an uncomfortable feeling for my thumb that runs along the side of the neck while playing. I’m not sure how to fix this but something needs to be done. I got the 25.5” that said it fit the Schecter Guitars. VERY Disappointed in the fit and finish of the LED strip to the point I nearly took it off and tossed it in the trash but for $200 I thought I would give it a try. So far it has been easier to learn guitar on than any other method I have tried in the past. I would expect better fit for $200 but so far that is my only complaint. That is why only 4 stars rating I almost went 3 stars but decided to give them a break.

Thanks so much for this feedback! What model Schecter do you have? We're happy to look into why the fit wasn't perfect. Also, what did you not like about the finish of the LED strip? We're always improving and are a company of engineers, so we can make incremental improvements and love customer feedback to do that. Feel free to email with pictures if you like and we can continue the conversation there!

So close

I love the concept but there are a few problems.

They must and I repeat must better fit the fretboard better. This is a real problem...I had to raise the action to get it to play right. Because it doesn’t fit right...and the strips being made of rubber bending the strings as you go up the fretboard makes a difference in playability. The connection from the fretboard to the unit is a crucial connection and it is way to connection severed when it got caught on a mic was a day old! They charged me $53 to replace the led strip!

The app is too basic. I like the scales but the songs? Seriously? Every track has 5 or 6 guitar parts and they don’t all play at once. Not only that but if you are trying to learn a song you have to cycle through all the parts and try to figure out how they fit together to try to make a single track from end to end.

Did you guys look at successful tab apps (tab pro) before making yours?

I understand the complexity involved (I made the same thing for my keyboard...but you probably went with a binary protocol making conversions from midi or tabs a freakin nightmare.

Cmon guys get it together. You spent a lot of time on the hardware charging us $200 to recoup costs...but you have compromised the usability by cutting corners!

You can still recover, but if you want to cater to serious players you need to make a pro level product.

Hi RSH- thank you for the feedback! We'd actually love to talk to you directly if you email (or we'll try and email you) so we can continue to fine tune Fret Zealot (both hardware and app).

Regarding when you caught your unit on a stand and broke it- we have questions. We purposely made the audio cable able to disconnect at either end for exactly that reason, so we're surprised the cable broke instead of the cable just releasing.

For songs, we spent 1000s of hours on a transcoder and it's getting better every month. We don't source from tabs (they don't have timing data), so we're coming from MIDI. It is not a simple binary protocol by any means.

Yes- we know tab pro. We're trying to talk to them to have them incorporate our SDK rather than us trying to reiterate all the hard work they've done. It's a great help if you email them and say you want them to support us! Our SDK would let you use Fret Zealot right from their existing app :-). We already have a few other partners lined up for this, including GuitarPro files. That's next on our development plan!

Hopefully we'll be in touch to discuss these items further!
