Asheville Music Tools APH-12 Plus Analog Phaser

The APH-12+ is a member of our “small batch” family, released occasionally in limited quantities. It brings you variations and options that we were unable to include in our standard release, including new features, topped off with a premium color-shifting finish.

When designing the original APH-12, we were limited to 8 of 12 stage choices, simply because we were unable to find a rotary switch that mechanically worked with more positions. While we hated leaving sounds on the cutting room floor, we chose the 8 settings that were the favorites of the AMpT team. For the APH-12+, we provided a second switch to unlock the stages between 6 and 12. Now you can get your 7s, 8s, 10s, and 11s on. And yes, this phaser now officially goes to 11. We always asked ourselves, “If 6 was 9...” now you can hear for yourself. Let your purple phaze fly.

In addition to more stages, we added a 2nd assignable envelope follower, tuning it with slightly longer attack and release times to provide a unique slope with variable modulation parameters. Thanks to John at EAE for pushing me to include this feature, which was begrudgingly omitted from the APH-12 due to space constraints. This addition doesn't just allow you to use the LFO and envelope simultaneously; it also allows the envelope to be assigned to any of the EXPression inputs when an external expression pedal is not in use. To facilitate this, we added an input sensitivity control with both pre- and post-gain sources, along with both positive and negative modulation. Furthermore, we modified the CV input to accept bi-polar modulation and redesigned the power supply and preamp to significantly lower the noise floor. These additions greatly increase the range of sounds available to bring you the ultimate analog phaser toolkit.
