Sound — 2
Cheese. Not good cheese. Much closer to government cheese than any premium Brie. The sound that emanates from the GT-100 is stale, unprofessional and about 20 years behind. It kind of reminds me of my old DigiTech GSP 21 that I had as a kid. I will admit that the GT-100 sounds superior to its predecessor, the GT-10. However, sound is where the problem lies. It has a wide variety of cool effects, they just sound revolting. The delay quality is the only aspect of the Boss GT-100 saving this section of the review from getting a 1. I am surprised that this unit has garnered the amount of praise that it has. I understand how it could be fun for a beginner but not for this price.
Overall Impression — 2
I can't stand it. I think that it would be fun for a beginner at about 1/3 the price. For this price, it should sound much better! Like I stated earlier, for a brief moment, I think I stopped scowling at one of the delays but I don't see many redeeming qualities for the Boss GT-100.
Reliability & Durability — 10
Again, I must give credit where credit is due. This little mother is durable and built to last. I wouldn't be afraid to take it on the road, throw it off of a building or shoot it with flamethrower, put it in a case, lock it in the trunk of my car and then drive it off of a bridge. In fact, that's exactly what I would want to do after listening to its horrendous tones for any length of time. However, if your ears interpret tones in a manner that I refuse to understand, rest assured that this thing will probably outlive the cockroaches.
Ease of Use — 10
Well, it certainly is easy to use. It takes a couple of minutes to get the basics and might take a week to really master but you don't have to be Nikola Tesla to work the thing. It has 200 presets which are immediately accessible and the only real work is creating your own 200 programmable user memory slots. The redesigned user interface is an improvement for Boss. And... The power supply is a standard DC 9V and the knobs all basically do what they're labeled to do.
