Ace is a faithful free digital emulation of a legendary 1950s, American, all tube, tweed, 5W amp. They 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.
For added flexibility, speaker emulation can be switched out in case you want to use a different speaker emulator. Ace also features 2x, 4x, or 8x selectable oversampling.
Simple controls and a conservative CPU usage make ACE easy to use in live settings as well as for re-amping.
Every component and interaction between components in the signal path has been accurately modeled. Since the original amp has a small, 6”, speaker they have used an impulse response of a small speaker for the cabinet emulation. By using an impulse response of a small speaker for cabinet emulation they have preserved the natural bass roll-off, a consequence of inability of a small speaker to faithfully reproduce bass frequencies.
To make Ace more versatile, they have added to the model two of the most common amplifier mods, removal/adjustment of the amount of feedback and addition of grid stopper resistors. The amount of feedback directly influences the gain whereas grid stoppers among other things mediate the blocking distortion.
Ace’s conservative CPU usage makes it suitable for live performance uses.
