Hi, I need some advice on choosing an amp for my 12 y.o. daughter. I am basically limited to just the following amps due to availability in my country: 1. Peavey KB4 (75watt, 1x15, $427) 2. Peavey KB5 (150watt, 2x10, $590) 3. Laney AH150 (150watt, 1x15, $424) 4. Laney AH300 (300watt, 1x15, $604) All four amps are able to handle bass guitar, keyboards, electronic drums, mic. According to the manual, the Peavey has a frequency range of 20Hz-20KHz. According to Laney Support, the Laney AH300 has a frequency range of 60Hz to 16kHz. She intends to use the amp for bass (about a year from now once she is better at basic guitar), Vdrums (right now) and vocals (right now). She already has a separate Roland Cube 80xl amp for her electric guitar. In terms of planned use: 95% of the time, the amp will just be at home for practice, so weight isn't a real issue, it won't be going anywhere often. But I am trying to consider the 5% of the time she will eventually use it to perform with fellow band mates on a stage/gym which seats 300-500 people. I am hoping the amp will last her for the next 10 years as a student. She just started playing elec. guitar and drums. I've read the comments on 1x15 vs 2x10 and honestly I still don't get it. I am leaning towards the Peavey, but only because of the existence of positive reviews on it. The only reviews for the Laney are older models AH200 and AH100. So my question is: 1. I could use some advice and insight to help me make an informed decision. 2. Would a 75 watt 1x15 be better than a 150 watt 2x10 for bass, drums and vocals in this situation? Thanks in advance, --eric ps. I don't play any instruments at all, so all this is new to me.
