Here is a blast from the past, the Yamaha KS-100 keyboard amp. Bought it cheap. It has a small horn, 4 imputs, 15" speaker and rated for 100 watts (I think RMS). It's heavy but not too bad. On the back it says "200 watts", but it is 100. Never tried it yet with drums, but it has some features I really like. The 4 imputs are what I need since I have 4 outputs, each assigned, snare, kick, toms and cymbals. The price was so good I had to buy it. It kicked the keyboards out really good so it should work ok for drums. I couldn't stand in front of it with the key boards cranked. The lows sounded good. I'll post further findings when I hook my rig up to it.
