RockAmp is a high gain tube guitar amp simulation.
No specific hardware simulated, no advanced circuit emulation algorithms used – just tuned to sound good. It is useful for rock and for low to mid-gain sounds, but it is also capable of some high-gain tones.
Features 3 drive modes – CLEAN, ROCK and METAL which differs in gain amount but also in distortion character and pre-equalization used.
BRIGHT switch engages algorithm which accentuates higher frequencies dynamically. It is very sensitive to the input signal level (this can be adjusted by INPUT).
PRE Equalizer not only shapes input signal frequencies but in ROCK and METAL drive modes also significantly affects the drive level and character.
POST Equalizer shapes output signal frequencies.
GATE features low pass filter on input signal controlled by envelope follower. Useful particularly for higher gain sounds, should be turned off for quiet lower gain sounds.
TIGHT affects how fast is the drive response to signal (the more tight – the faster drive amount falls).
FAT adds even harmonics to the signal.
BODY adds some middle and higher mid-range and some more aggression.
MOD is modulation effect which can be set up like chorus, flanger or vibrato. In mode I there is one delay line, in mode II there are two delay lines creating richer chorus effect.
DELAY is simple delay effect with overdrive and filter in feedback loop – it can be introduced by THRESH amount.
This is only Amp simulator, it does not feature Cabinet simulator. For cabinet simulation you can use some free Impulse response VST plugin like Ignite Amps NadIR.

Tube Amp applies asymmetric tube triode overdrive usually found in single-tube microphone pre-amp boxes.The sound this plug-in produces varies from a mild warm overdrive to a fuzzy distortion. Tube Amp also includes a -6 dB/oct low-pass filter that is built-in into plug-in’s valve modeling equation, and can be used to imitate a lower-quality tube triode.  Beside that, Tube Amp has a switchable output saturation stage which can be used to additionally overdrive the output signal. It features all standard advanced Voxengo plug-in features like full multi-channel operation, channel routing, built-in oversampling and other functions.

• Asymmetric tube triode overdrive.
• Stereo and multi-channel processing.
• Mid/side processing.
• Preset manager.
• Contextual hint messages.
• Two processing modes.
• Internal channel routing.
• Up to 8x oversampling.
• Undo/redo history.
• All sample rates support.
• Additional output saturation stage.
• Channel grouping.
• 64-bit floating point processing.
• A/B comparisons.
• Zero processing latency.
