I listened to an interview with John Entwistle on the King Biscuit Live CD, at one point when discussing his gear he says he would run two Sunn amps, 'staved into to one another to make them distort'. Does anyone know what he means by this? It was a pretty awesome tone he was getting.
I'm assuming he said "slaved", as Sunn amps were commonly used as slave power amps. Slaving is basically running the preamp of a head (called the master) into a separate power amp (called a slave). This would essentially add extra power and allow you to use more cabs.
Maybe he meant deliberately damaging (slicing) the speaker cone so it would distort. Apparently that was a practised in the early days when amps did not produce enough distortion on it's own. Wasn't The Who famous for destroying their equipment on stage?
Back when, all power amps were called slaves. You'd have a basic amp, say a mixer amp for P.A. and add slaves and speakers to increase the wattage. The first 1000w P.A. that I saw / heard, was The Who's, a 5 channel Wem Audiomaster mixer, yes a whole 5 channels, driving 10, 100w Wem slaves all stacked on top of each other in a tower. The slaves were driving Townsend's old and smashed cabinets, 16 per side.
Typo. He meant his amps were "Steved", as in modified by noted London underground amp tech Sir Reginald Steve Chesterbottom
If we go with the verb form of the word, it was Pete who did all the staving, as seen at the end of this vid:
maybe he meant hee was running the line out into the inst level in. That will distort for sure. I've heard of some bands running SPEAKER level out into the inst level input. But I understand it was for recording and would blow the amp in about 20 minutes.
