Peavey JSX Guitar Amplifier Half Stack

JSX Head
Peavey and Joe Satriani set out to create an amplifier that would give the widest range of EQ options and gain structures possible.

This amp delivers sounds ranging from the Classic 50 to vintage British to the modern Triple XXX and all tones in-between. The versatile and comprehensive control section supplies a master volume pot and independent volume knobs for each of the 3 channels (ultra, crunch and clean). Tone shaping is accomplished through passive controls for bass, mid and treble on the clean channel, while the ultra and crunch channels utilize active low, mid and high controls. The clean channel is pristine yet warm and is specifically voiced to work well with effects pedals. The ultra and crunch channels have gain controls and fat switches to further assist in taming this thunderous tube-powered beast while achieving killer sound. Global resonance and presence knobs increase control of high-end tones, while a noise gate on the crunch and ultra channels cuts down on the excess noise generated by running the gain and EQ controls on high settings. Since the gate is fully adjustable, you can really clamp down, leave it slightly open or just turn it off.
