UPS should be delivering my bass any minute now, but I need an amp. At a local music go round they have a CRATE BX50DLX for $149.99 and a Kasino Concert (this is just based off the website). I have no idea what sounds good, I went to guitar center yesterday and played on a little cheap Crate BT10 and thought it sounded just fine, but I haven't heard better amps and hardly have an ear for the bass yet. I don't really want to go over $150 and want to buy today. I was leaning toward the Crate BT10 or BT15. WIll these be decent beginner practice amps, they are $89.99-$119.99, respectively.
