The ultimate stacking preamp, vintage drive, booster, distortion, and much more.
With an internal voltage boosted up to 34v, the 112+ runs hot and pushes its circuitry to the boundaries of what it can do.
This pedal sounds good at pretty much any setting, but it really rewards you for taking the time to sit down and getting to know it, as the sheer breadth of the range of sounds that are possible might not be obvious at first glance.
Details for Nerds
The 112+ takes a standard Boss-style 9.6v, center negative Power supply connector as used on most guitar pedals. Internally, however, an LT1054 charge pump is used to boost that up to 34v for an insane amount of headroom.
From the input, the signal encounters a discrete JFET preamp where it gets a big [mostly] clean boost. Even when your Drive Control is turned down to 0, this clean boost will be present, giving you a the ability apply a nice sizzly boost with an active EQ .
After the preamp, the signal encounters the 'Voice' control, which sets how much bass is passed into the drive section. The way this is set will affect the overall character of the drive's saturation (clipping).
Minimizing the amount of bass being driven into clipping leads to a vintage rock sound, whereas letting it all through provides a fat, heavy dirt tone. Halfway between the two, you get a more standard drive sound - a bit of sculpting that accentuates the guitar's primary frequencies and suppresses anything that might overlap with a bassist's playing.
Next, the drive section is found. The amount of gain applied is controlled by the 'Drive' Knob. The more gain, the bigger the signal. Once big enough, it overcomes the clipping threshold and distorts in an interesting, dual-stage way.
The signal then gets re-amplified before being sent off to a 3-Band Active EQ, offering boost/cut capabilites for each band, as controlled by the 'Bottom', 'Mid', and 'Top' conrols on the front panel. These controls give you the ability to tailor the sound for the purpose you intend to use the pedal for. From relatively transparent, to bright treble boost, to chunky, to crisp, to mid-heavy, to scooped, you have enormous control.
Finally, an active volume control lets you control the final volume, from bedroom-friendly levels all the way up to slam-the-clean-channel-of-your-amp-so-hard-it-becomes-a-dirt-channel loud.
