Ace

Ace free amp-simulator by Shattered Glass Audio

Ace is a free amp simulator VST, Audio Unit plugin developed by Shattered Glass Audio. Compatible OS(s): Windows 64b, macOS.

Ace is a faithful digital emulation of a legendary 1950s, American, all tube, tweed, 5W amp. We have added to the model two of the most common amplifier mods: adjustment of the amount of feedback and addition of grid stopper resistors, both of which can be turned off for the original amp sound.

Simple controls and a conservative CPU usage make ACE easy to use in live settings as well as for re-amping.

Features:

Accurate modeling of the whole circuit to capture dynamic interactions between amp stages.

Authentic 12AX7 and 6V6GT vacuum tube models.

Models of the two most common amp mods.

Adjustable strength of the input signal with up to 12 dB boost.

Cabinet simulation that can be switched on or off.

Selectable 2x, 4x, or 8x oversampling.

2-Band / 4-Band

2-Band / 4-Band is a free routing VST plugin developed by rhythminmind.net. Compatible OS(s): Windows.

4-Band and 2-Band are 100% transparent Four/Two-Band Frequency Divider VST plug-ins for use in modular mixing environments. They split the audio into bands whilst keeping the audio integrity intact. This can be used for frequency dependent FX and mastering purposes. It uses subtractive phase techniques as opposed to minimal phase EQ. In other words the basic signal flow design framework won’t change or color your audio (You can test this by double bussing & inverting the phase).
