TASCAM MP-GT1 Portable MP3 Guitar Trainer 

A great piece of kit, once you understand it's issues.
I have had a lot of problems getting the MP3's that I load onto the device to play and display correctly. The manual gives a few hints, but the main issues are:

Songs wont play
Songs are distorted
Title or artist won't display

After a lot of playing around with the MP3's, I got the definitive setup to make them work every time:

MP3's recorded with a bit rate of 44100hz, 256kbps, stereo

ID3v2 tags with no cover art or lyrics (the MP-GT1 only needs 'Title', 'Artist' and 'Album' but it fails to display correctly if there is too much extended ID3v2 info)

Once I got into the habit of applying these settings to any songs I loaded to the trainer, I never had any more problems.

Other than this, the kit is great, although slightly bulky. My iPhone does exactly the same thing with an iRig attached and various different apps, but the Tascam is far less fiddly.

I bought this over a year ago and it has been a good tool. However my laptop has all this and sounds better. The GT1 is however quite portable and great for sitting on the couch practicing. I've used it on the treadmill a number of time when my wife would not let me use her IPOD.The GT1 doesn't like varible bit rate files though. Its locked up over those and then you have to get out the paper clip.I'm not crazy about the overdrive and distortion sounds but thats not its forte.Battery life seems reasonable and it has a good amount of memory.It has good mixing and playback level options.Would I buy it again....Yes.

If you are an older player like me who learned to play years ago but haven't played consistently for a long time, the TASCAM MP-GT1 trainer is for you. Finally, I can learn those classic licks which have always seemed to escape me.The loop feature allows me to learn at my own pace and the number of effects combinations is almost endless. My only complaint is you must use MP3s recorded at 128kbps (most of my library is at 192kbps) and the sound is a little muddy at very slow tempos. These are minor inconveniences when weighed against the speed at which I am now learning. Buy this gear and become the rock star you've always wanted to be.

I have found this device (Tascam MP-GT1 Guitar Trainer) to be indispensable to me for learning songs, although honestly I have found the build quality to be lacking - in fact, I have had several units break or die on me, but in each case found no other product that offers the same combination of features that make the MP-GT1 so useful for me (certainly not in such a portable and affordable package), and have continued to replace it by looking around for good deals. The three features that make it invaluable for me for learning songs for my various cover bands are: the ability to loop parts; the ability to slow down parts without changing the pitch, to learn those fast solos and runs (I don't care that much that the sound quality deteriorates when you slow it down, I'm just trying to pick out the notes); and the kicker (that a comparable IPhone or computer app doesn't have), the ability to feed my keyboard into it with a 1/4" cable, and listen to myself and the mp3 together in headphones - thus being able to work on my songs without keeping the wife and kids awake or just driving them crazy! Since I play keyboards and not guitar, I don't use or care about the effects section. They should market these machines to us keyboard players, they are just as useful or more for us than for our guitar-slinging brethren I think.

I got an MP-GT1 a few months ago. I've been very happy with it. The slow-down feature is great for learning licks (if you slow down a lot, the music does get distorted, but I have a feeling that's more due to the lossy nature of MP3 encoding rather than the unit). The loop feature is great for practicing alone, or when you're getting an arrangement down with a band. The key-changing utility is great, too, since my band frequently plays songs a step or a step and a half down. The built-in guitar effects processor is not the best, but it works well enough to get the job done (I've even used it for practice when I forgot my pedal board). I have not hit the unit's capacity yet, and I've got a lot of songs on it. Managing the files on this device is easy to do from Windows. I have not had any problems creating or browsing folders and subfolders on this device.

It has rugged metal frame because you are going to drop eventually. It's easy to load mp3s from windows. The sounds are a not what you would want from a guitar processor but they work well for learning. I rarely use headphone with it. I usually run it into the CD input on my amp and play along. A little pricey but cheaper than lessons. I'm really more of a bassist so I have the bass trainer also.

I've had my unit for about 6 months now and have been quite satisfied. The only thing that I felt could have been designed better is the power switch, it's like a little combo-lock. Other than that it helps me learn licks I need for our worship band that I need to play. For the price, I doubt that there is anything else like it available. I'm glad they kept working on it from the CD version (which I own) I'm sure we'll see this continue. I can't wait to see what shape this will take in a few years.

This product has recieved mixed reviews, but I thought I'd take a chance on it. Man, I'm glad I did. I live in an apartment and have always had to practice with the amp volume turned down low. Now I can practice the guitar with my favorite songs cranked up. As an added benefit, I ordered a 3 foot guitar cable and installed a simple, self adhesive belt clip. No more cable tied to the amp. Now I'm free to walk around the room or sit anywhere while I play.I've only had this for a couple of weeks, but I love it. It's definately taken my guitar playing up another level.

Purchased this devise after playing with a friends CD version. This devise does exactly what it is advertised to do...Guitar Trainer. It's not an amp, or an IPOD, I did not expect it to be. Only complaint is it does not have an output feature that would allow it to be put inline with my amp. I love the tempo adjust while maintaining descent tone. Helped me through learning solos.

I just got it and I just can't put it down. all features work as advertised. Pith change, distortion, flanger effects work fine, This is the perfect trainer. The guitar canceation feature has very low volume but accomplishes it purpose (practicing). If you are interested in guitar in anywa, buy this product.
