The 15 and 30 watts have the same features, except that the 30 watt has a 10" (or is it 12"?) speaker and footswitch capabilities.

from the 75 watt upwards, the amps have more features and more sounds...but all in all, porbably the best value for money around.

I've got the 30, and it's got a 12" celestion speaker (the 15 has like a 10" no-name speaker I believe) it's got the footswitch capabilities, and it also has a line out for headphones or direct recording. other then that it's the same 4 channels as the 15, but the 75 has like either 6 or 12 channels (can't remember) but 75W of power was alot more then I needed.

btw, he meant he wanted an ibanez guitar (good choice btw ;) ) not an ibanez amp.

also, you didn't mention what price range you had, what style of music you play, and what you would be using the amp for (gigging, practice in your bedroom, etc.)

since you've only been playing for 6 months, I assume you are just using it for bedroom practice, in which case 40W of power is waaayyy too much. you shouldn't need more then 15 or 20. more wattage doesn't mean more sound quality. and I think you would be best off with a spider II 15, as it's cheap, versatile, and won't kill you neighbors.
