I need your opinion about this bass guitar Peavey?

Well, it at least has two pickups on it so, it will be find for you to learn with. The amplifier is not good for much of anything except practicing in your room. As soon as you can afford it, you should try to get a BOSS ME-20B or ME-50B bass effects processor. That will provide you all of the bass effects you might need so you can learn what they sound like and how to use them. Then, when you are ready to play with a band, get you r self a good 150 to 300 watt bass amplifier like the Behringer Ultrabass. With a 150 watt bass amp and a BOSS bass effects processor, that bass should sound pretty decent so, unless it has really poor hardware and electronics, it will even last you a while before you need to trade up. Your sound comes primarily from the effects processor and not the bass itself.
