Different from the early 90s typical multifx units. Strives for controlling or accounting for various specific parameters of amp emulation (power tube, output transformer, guitar speaker, cabinet, and mic), not just speaker simulation. Doesn't go into the level of amp-emulation detail of the ADA Ampulator, but is miles ahead of more typical preamp/multifx processors such as the DigiTech 2120 with "programmable speaker simulator" which has little more than two settings: on or off.
Strives for total tube-amp emulation, not just "speaker simulation", breaks out of the mere, so-called "preamp" league -- which says "pre" "amp", which means *not* amp-like.
Might have a badly needed feature, pre-distortion eq.

>The Tom Scholtz Rockman also does a lot of eq tricks.
What sort? This intelligent design seems to have been carried over into all of the Rocktron products.

http://www.rocktron.com/grt/austin.html - Brush the dust off your boots and get ready to plug into one awesome Overdrive pedal as the Austin Gold joins Rocktron's pedal family. A superb blend of light overdrive that enhances, without changing, the sound of your favorite amp. Unique to the Austin Gold is its "Pre-Bass" control... eliminates problems with too much "fuzzy" bass, or the opposite problem of being a weak and thin sounding overdrive. With the Pre-Bass control, many overdrive textures can be exploited. It's almost like having an entire arsenal of various overdrive pedals in one, by simply adjusting one control! With its simple control layout of "Drive", "Pre-Bass" and "Level", the Austin Gold is very simple to use. By adding a maximum of 30dB of gain, it will not overprocess, but instead will add an entirely new dimension to your amp setup! Review.

The VARIAC ADJUST parameter adjusts the level at which the preamp stage in the Chameleon begins to distort. A Variac is a voltage attenuating device that plugs into an AC wall outlet and adjusts the voltage level to any device which is plugged into it. For years, many guitarists have plugged their amplifier heads into a Variac and reduced the voltage coming into the amplifier from the AC wall outlet. This allows the amplifier tubes to reach saturation at a lower input level and increases the gain produced. The VARIAC ADJUST parameter operates in a similar manner as a conventional Variac - where lowering the parameter value lowers the level at which saturation will take place.
official product page for Rocktron Chameleon - " No other preamp offers the tone shaping tools like pre and post distortion EQ capabilities, Variac, High and Low Gain modes, and slick extras like Pentode, Triode, and Solid State preamp voicings. Ask anyone who has used the Chameleon in the studio and they will rave about the untouchable Speaker Simulator. Instead of a limited graphic EQ (or even no EQ) like most preamps, the Chameleon offers: Speaker Size (8", 10", 12", 15", and full range settings). Mic Placement allows a good cut without the "buzziness", while the patented Reactance parameter renders serious chunk and low frequency options that are not available on any other preamp or mixing board EQ section. Using the stereo XLR outputs makes it a natural for live direct-to-P.A. applications as well. Of course, the Chameleon On-Line also has a healthy serving of Rocktron's world-famous effects.
