The JSX Mini Colossal combines a 12AX7 preamp tube and an EL84 power tube in a class-A topology that has no negative feedback. The new Peavey-exclusive Power Sponge™ output attenuator continuously adjusts the power output of the amplifier from 5 watts to 0 watts while maintaining the distortion characteristics of the class-A power amp at any volume level.
A built-in transformer-balanced XLR direct output with a unique microphone simulator allows players to send the amplifier signal to a recording device or front-of-house mix without the use of a microphone, while an onboard optical tremolo circuit with speed and intensity adjustments adds a vintage-amp vibe.
“There’s a dynamic thing happening with class-A amps that is completely different from modern- style amplifiers,” said Satriani. “A modern amp like the JSX Head allows you tons of gain, regardless of the amount of pressure you play with, but when you play through a class-A amp and hit a note very lightly, it doesn’t sound like it has any gain behind it. With each little increment of force that you add to the picking stroke, the amp goes into more and more overdrive.
“I found that when I write, I get myself into situations where a class-A amp is what I need to make the track work. That led us to create the Mini Colossal. It provides an entirely different guitar dynamic from the three-channel JSX, yet it’s very complementary on recordings where I used the amps together. Artistically, it fit what I was trying to convey.”
The JSX Mini Colossal will be available from authorized Peavey retailers in Q1 2007.
