Amp Rack is a powerful guitar amp simulator.
You can combine a choice of amplifiers and speaker cabinets with stomp box effects.
The input and output level meters on the far left and right show the audio signal level.
The main elements of the effect are displayed in a horizontally scroll-able chain:
-
Pre-Effects
Up to six common guitar effects can be placed before the amplifier in the signal chain. Each effect features a stomp-box-style On/Off button and individual parameters.
Tap the "+" button to add an effect, or an effect's name to select a different one or to remove it.
To change the order of the effects in the chain, long-tap on an effect and drag it to another position.
-
Amplifier and Cabinet
Tapping it toggles the bottom panel where amplifier, cabinet and microphone parameters can be configured.
-
Post-Effects
Up to six common guitar effects can be placed after the amplifier in the signal chain. Types and usage are identical to the Pre-Effects.
-
Master EQ
This is a three-band equalizer with a frequency and a gain control for each band. To activate/deactivate an equalizer band, tap the corresponding round yellow button.
-
Tuner
If enabled, the graphical display indicates the currently played pitch as a note. If the played note is flat, the bars left of the middle will light up. If the played note is sharp, the bars right of the middle will light up. If you play the correct pitch, the middle bar turns green.
Tap the display to enlarge it and to reveal all Tuner controls. See the chapter Tuner for more details.
NoteIf the Tuner is enabled, the amplifier and effects are disabled so that you hear the unprocessed tone of your instrument.
-
Master Volume
To change the volume of the output signal, use the volume control. Toggle the Master stomp box to mute/unmute the output.
Effects
- Wah Wah
-
Pedal – Controls the filter frequency sweep.
- Volume
-
Pedal – Controls the level of the signal passing through the effect.
- Compressor
-
Intensity – Sets the amount by which an input signal is being compressed.
- Limiter
-
Threshold – Determines the maximum output level. Signal levels above the set threshold are cut off.
Release – Sets the time after which the gain returns to the original level.
- Maximizer
-
Amount – Determines the loudness of the signal.
- Chorus
-
Rate – Allows you to set the sweep rate. This parameter can be synchronized to the project tempo by enabling the SYNC button.
- Phaser
-
Rate – Allows you to set the sweep rate. This parameter can be synchronized to the project tempo by enabling the SYNC button.
- Flanger
-
Rate – Allows you to set the sweep rate. This parameter can be synchronized to the project tempo by enabling the SYNC button.
- Tremolo
-
Rate – Allows you to set the modulation speed. This parameter can be synchronized to the project tempo by enabling the SYNC button.
- Octaver
-
Direct – Adjusts the mix of the original signal and the generated voices. A value of 0 means only the generated and transposed signal is heard. By raising this value, more of the original signal is heard.
- Delay
-
Delay – Sets the delay time in milliseconds. This parameter can be synchronized to the project tempo by enabling the SYNC button.
- Tape Delay
-
Delay – Tape Delay creates a delay effect known from tape machines. The Delay parameter sets the delay time in milliseconds. This parameter can be synchronized to the project tempo by enabling the SYNC button.
- Tape Ducking Delay
-
Delay – Tape Ducking Delay creates a delay effect known from tape machines with a ducking parameter. The Delay parameter sets the delay time in milliseconds. This parameter can be synchronized to the project tempo by enabling the SYNC button.
- Overdrive
-
Drive – Overdrive creates a tube-like overdrive effect. The higher this value, the more harmonics are added to the output signal of this effect.
- Fuzz
-
Boost – Fuzz creates a rather harsh distortion effect. The higher this value, the more distortion is created.
- Gate
-
Threshold – Determines the level at which the gate is activated. Signal levels above the set threshold trigger the gate to open, and signal levels below the set threshold close the gate.
- Equalizer
-
Low – Sets the level of the low frequency portion of the incoming signal.
- Reverb
-
Type – A convolution-based reverb effect. This parameter allows you to switch between different reverb types (Studio, Hall, Plate, and Room).
Amplifiers
The amplifiers are modeled on real-life amplifiers. Each amp features settings typical for guitar recording, such as gain, equalizers, and master volume.
To select an amplifier, tap it in the chain to bring up the bottom panel, tap TYPE, tap the left drop-down menu and select the model that you want to use. Select No Amplifier if you only want to use the cabinets and effects.
-
Plexi – Classic British rock tone; extremely transparent sound, very responsive.
Plexi Lead – British rock tone of the 70s and 80s.
Diamond – The cutting edge hard rock and metal sounds of the 90s.
Blackface – Classic American clean tone.
Tweed – Clean and crunchy tones; originally developed as a bass amp.
Deluxe – American crunch sound coming from a rather small amp with a big tone.
British Custom – Produces the sparkling clean or harmonically distorted rhythm sounds of the 60s.
All amps provide the following sound-related parameters in the AMP section of the bottom panel, which have a significant impact on their overall character and sound:
- Gain
-
Sets the amount of boost for the amp.
- Bass
-
Allows you to raise or lower the low frequency part of the signal.
- Middle
-
Allows you to raise or lower the mid frequency part of the signal.
- Treble
-
Allows you to raise or lower the high frequency part of the signal.
- Presence
-
Allows you to raise or lower the upper mid frequency part of the signal.
- Master
-
Sets the output level for the amp.
The different amps keep their settings if you switch models.
Cabinets
The cabinets available on the Cabinets page simulate real-life combo boxes or speakers. For each amp, a corresponding cabinet type is available, but you can also combine different amps and cabinets.
To select a cabinet, tap it in the chain to bring up the bottom panel, tap TYPE, tap the right drop-down menu and select the model that you want to use. Select No Cabinet if you only want to use the amps and effects.
If you enable the Link button in the center, the plug-in automatically selects the cabinet corresponding to the selected amp model.
Microphones
To bring up the Microphones page, tap the amplifier in the chain to bring up the bottom panel, then tap MIC.
- Mix
-
You can crossfade between the characteristics of a large-diaphragm condenser microphone and a dynamic microphone.
- Mic Position
-
These microphone positions result from two different angles (center and edge) and three different distances from the speaker, as well as an additional center position at an even greater distance from the speaker.
