From Mesa Boogie:
The THROTTLE BOX EQ™ combines the enhanced tone shaping power of our popular Boogie® Five-Band Graphic Equalizer with footswitchable HI/LO performance Modes and easy “Top Panel” access to the previously internal BOOST feature of the original THROTTLE BOX™.
With the worldwide success of the THROTTLE BOX™ overdrive, we saw potential for an even more powerful version that included our classic Five-Band Graphic Equalizer. With the added shaping power the on-board Five Band EQ creates the THROTTLE BOX EQ can go anywhere you want to take it stylistically. The middle range of the GAIN control delivers tight, stinging overdrive that–depending on whether you choose LO or HI GAIN Modes–can cover everything from Blues to Modern Metal with plenty of attitude and an urgent percussive nature. Cranking things up into the upper one-third of the GAIN control in HI unleashes a hot-rod that’s blistering with searing top-end harmonics.
For Hard Rock and Metal our Graphic EQ set to the popular mid-scooped “V-Curve” has over a four decade track record of creating the heaviest sounds around. With limitless curve possibilities, the Graphic expands the potential for sonic diversity across all styles as well as being able to unleash Mayhem.
Like the original, this expanded THROTTLE BOX includes two Modes but here they are controlled by a HI/LO footswitch that enables you to have two gain regions to choose from during live performance. There are also dedicated HI LEVEL and LO LEVEL Output controls, allowing you to set the desired volume level for each Gain Mode individually. The EQ can be assigned to either or both of these Gain Mode choices so that it becomes active with the desired Gain Mode selection. In addition, we’ve fitted a MID CUT control that allows global scooping of the mids in addition to whatever you might do with the Graphic sliders. And finally, the internally selectable BOOST switch hidden under the Bottom Plate on the original THROTTLE BOX appears on this EQ version as an easily accessible Top Panel BOOST switch for extra girth and a bit of gain enhancement. We’re confident this pedal will exceed your expectations and provide an inspiring tool for expression.
? The Atlas III is a medium-gain preamp booster. While staying relatively clean and transparent, the Atlas III adds subtle color and harmonic overtones, which become more apparent as you increase gain.
Specifically created for pushing the front end of tube amps, the Atlas III was designed to do so in a rich, warm way; while adding a touch of sparkle in the highs, and never muddying up the lows. The net result is a very natural sounding gain, without over-emphasizing any specific frequency range. The Atlas III obtains this tasteful organic coloration via its discrete preamp design.
The gain control is completely useable throughout its full rotation. Plenty of gain to overdrive your amp's tubes, without melting anything (probably).
Inside of the Atlas III you will find a mini switch which allows you to select the phase of the pedal's output, in or out of phase with the input source signal. This is extremely helpful when using a multiple amp set up, and for studio situations where phase becomes an extremely important factor.
The Atlas III is completely hand-soldered and handmade in Portland Oregon to the highest degree of quality possible. These are truly artisan-crafted tone devices, sparing no detail within or without. The Atlas III utilizes true-bypass switching via the heaviest duty mechanical footswitch available, while your tone is transferred via quality open-frame Switchcraft jacks. Open one up and you’ll see an unparalleled display of craftsmanship; with immaculate hand-soldered PCB, detailed military-spec wiring, and custom Spaceman heavy-duty battery connector. On top of the USA-cast aluminum enclosure sits a durable, engraved vinyl faceplate and vintage dim-able indicator light. This pedal is truly built to last a lifetime.
The Chrome Edition Atlas III features triple-plated "show chrome", vintage Daka-Ware control knob, and heavy-duty vintage Aerospace dim-able indicator. The Copper Edition features double-plated polished copper, oxblood vintage-reissue control knob, and vintage dim-able indicator. The Light Blue Edition features a sparkle metallic light blue powder-coat, vintage-reissue control knob and vintage dim-able indicator. The Black Edition features a textured black powder-coat, vintage-reissue control knob, and vintage dim-able indicator.
