I remember how
 awesome it was to finally get the Peavey JSX amp when I was 13, that thing
 shredded.  At the time, I was beginning
 to play more performances, which called for a louder and more versatile
 amp.  The JSX amp is actually a tube amp,
 which are higher performance that normal amps, and the JSX in particular requires
 a few minutes of warming up the tubes before any sound starts to come
 through.  There are two dials on it, one
 is power and one is standby.  If you flip
 off the standby switch, the amp would remain warmed up, yet wouldn’t be
 on.  Almost like a rest mode to keep the
 tubes warm.  I remember  deciding between a half stack and a combo amp
 (pictured), and ultimately went with the combo amp because of its value and
 versatility, while buying a separate head and body amp could add up expenses.
