Hiwatt Custom 20
A lot easier on the back than the Custom 50, the 20 watt version is ideal for most band gigs. Although only 20 watts it has enough grunt to compete with any drummer.
Unlike the 50, this amp with break up when when driven giving a great classic British rock sound. At normal stage volumes it also takes pedals very well.
It has a very mid-range focused sound, with heaps of tube saturation even on the cleans. And the soft response of a classic vintage amp which I love for the extra interactiveness with the guitar and playing style that it gives.
