I like both of them. Reeves 18. I snagged one of these over on the Gear Page and it's a great match for the SG. With the volume knob you can get really clean and chimey tones, but it gets nice and dirty too if you want it to. Loud as all heck for only 18 watts! I also have a Reeves Studio/Stage and it's more like 20/40W. Killer tone from that amp. I don't think they make them anymore, but it's a sweet amp ... that one is made in the UK and sold over their as a Hiwatt. :) Hiwatt DR103. This to me is the ultimate SG tone. A SG with P90s sounds the best I think. The amp is so touch sensitive, it's almost a religious experience. It's also freakin loud, so you need a good attenuator and fuzz pedal.
