Sound — 10
I currently using a Ibanez Gio, and a Laney LV300 amp. (I origanaly used the GT3 in the effects loop but afer purchasing a dunnolop wah pedal I put it before the amp.) I found that the GT3 sounds really good and allows you to create a variety of sounds. I was really impressed with the accousitic simulator, noise gate, and distortions in the GT3. The only thing I would say is that the sweep on the wah isnt that great but I don't know whether that is me or the GT3.
Overall Impression — 10
I play a lot of Metal and classic rock, and have been playing for 5 years. Before buying it I really didn't know much about guitar effects but now after talking with some of my friends Who play guitar the GT3 seems like a great purchase, and I haven't looked back after buying it.
Reliability & Durability — 10
I find the GT3 really reliable and I haven't had any faults with it, and neither did the previous own of it. I haven't played any gigs using the GT3 but I practise in a band all the time and I can rely on it to keep working throughout the practise. And even during practise the durability of the GT3 is shown when I need to quickly put in a new patch and edit current ones.
Ease of Use — 10
Before getting the GT3 I had no previous experiance of guitar effects. After purchasing it I was really impressed with the GT3's ease of use, and within minutes I had the sound I wanted from it. I found editing the patches very easy and anything I needed to know was in the instruction maunal.
