This is our main bass amp (we have others...), a Hiwatt PA head, 200w of KT88 valves. Headroom to the sky, and clean all the way up. Power..? It can double as a concrete buster for reducing war-time Omaha Beach bunkers to dust. We seldom need, nor want, to dial up beyond 9 o'clock. The HH cab helps, of course. How much does it all weigh..? A little less than Jupiter (but not much...)...
