This amp sounds really good and feels great playing it via Unison preamp in Apollo Twin X on MacStudio. One thing to note however is even with proper gain staging on Apollo Twin X Guitar input, the presets are way too loud as is and red line the pre-fader metering like crazy. You have to turn way down the master volume on plugin or turn down the power soak control. Once you get used to how all the controls interact the amp sounds great and you can get really good lead or crunchy rhythm sounds. Add a bit of room reverb and you’re set for very realistic sounds.
