| I have tried the G-100. They also have a new b-100.
Anyway, the G-100 is ok. The only really good setting are the clean. The OD (texas i think it was called) is ok, The Distortion is ok. I tried this only with guitar though, not bass. The effects were pretty good...better than the od/distortion options. It sounded really good when I used my own dirt pedals, which defeated the whole purpose to me. When I jammed with my buddy using his GNX 3, the GNX 3 blew it away. I now have a GNX3000 and it is much better. The bass models are ok on it, but only 3 of them are really worth anything, I find real amps sound better though.
Anyway, if you get the G-100 for about $125 or less, it's worth it. |
