My little Egnater Tweaker head is 15 watts, and I use it at very low volumes. However it is pretty loud when I turn it up, Deluxe Reverb loud. I do not use controlled feedback, but I do use a tube overdrive stomp which imitates controlled feedback and under/overtones to a small degree, so I just use the sustain of the pedal to get a small amount of that. Of course it is not like my long gone hundred watt Plexi and the Sunn 6-12 cabinet, but it suffices for home use. If I played out of course I would use my Hot Rod Deluxe, but I do not foresee that happening in this lifetime. I think the Tweaker head could stand up to a moderately loud situation however. I was surprised at how loud it is back when I bought it.
