100% Analog 12-Stage All-Pass Filter, Dynamic Phaser, Vibrato Pedal The Analoger Series APH-12 is a 100% analog 12-stage phase shifter with deep functionality in a compact footprin t. It delivers not only classic phaser tones, but many features and sounds not normally associated with traditional phasers. With a selectable number of all-pass stages from 1 to 12, and our signature control voltage processing, multiple flavors of modulation sit at your fingertips. The APH-12 delivers classic or extreme phase shifting, faux Leslie warble, vibrato and tremolo, vocal envelope followed filter funkiness, and striking multi-peak EQing. Designed by Hawker, this pedal continues the legacy of high stage count phasers and adds some surprises and special features. Instead of simply updating a lost 12-stage phaser of the past, we rolled our own from the ground up. At the start of the APH-12 Phaser project, we spent much time deciding how to bring something special to the table with our unique Asheville Music Tools touch. We knew it had to go beyond the usual expectations of phasers to achieve new sounds coupled with cross-generational appeal. It couldn’t just recreate what Hawker or others had done in the past. Furthermore, it needed to be in a guitar and pedalboard-friendly format that balanced size, features and sound quality to keep it approachable. At its core, the APH-12 nails that classic 12 and 6-stage phaser sound with warm overdrive on tap. From there, we went a little wild. We exploded the low stage counts and out of phase odd stages to create vocal and filter sounds that are rarely heard in phasers. We know of no other phaser that has done this. Did you know that a 1 stage phaser is a high pass filter and makes for a great tremolo sound? Or that a 2-stage phaser is a notch filter? Or that 3 stages (with envelope control) can challenge any auto-wah out there? From there we created a uniquely sculpted regeneration circuit that sums the feedback at a different part of the loop than most phasers. This accentuates the notches of the comb filter and gives more pronounced resonance, for an attention-grabbing intensity without uncomfortable sibilance. Next we knew we had to add the envelope follower, based on our AFG-1 flanger circuit, to the APH-12 as well. This feature adds funky, expressive capabilities to your playing dynamics in a way that typical asynchronous modulation just can’t touch. If our beta testers are any indication, you will get lost in it!Then there are all of the signature AMpT touches you have come to expect, including our new saturation circuit with drive, our smooth and natural sine wave, exponential (rather than linear) LFO modulation, a two-speed LFO switch, and a calibrated mix switch to give you three distinct phaser sounds from subtle to deep phasing and vibrato. And of course, we added external expression or control voltage capabilities for those adventurous enough to go beyond the front panel controls. Developing the APH-12 was a fascinating learning experience: with all the excitement of a 12-stage phaser (and of course, there is nothing quite like a 12-stage phaser with a 2 minute sweep) we were surprised to learn how much we loved the under-explored character of the out-of-phase 3 and 5 stage modes, or the utilitarian tremolo-like sounds of 1 and 2 stage modes. Add on top of that the power of envelope followed modulation, and we knew we had something special. Far from a simple phase shifter, this is a versatile modulation toolkit for discerning guitarists and bold sound designers alike. Phase Module Sweep: Filter center frequency. Manually adjusts the All-Pass filter’s frequency from about 25Hz to 10KHz. When modulated this becomes the center frequency for the LFO or the start frequency for the envelope control. Resonance: Affects how much signal is fed back into the filters to adjust the intensity of the effect. Increases both the peaks and valleys of the comb filters. Extreme settings will produce self-oscillation, providing drone tones that are tuned by the SWEEP knob. Mix Switch: FX Mode: Favors the dry signal, tames intense settings.Phase Mode: Balanced mix, calibrated for deep phasing.Vibrato Mode:100% wet signal for true vibrato tones. Drive and Control Module: Drive: Controls a JFET-powered preamplifier with 2nd JFET saturation circuit for up to 30dB of boost with increasing saturation and mid emphasis as gain is increased. Use for level matching or to add harmonics to the filters.Stages: 8 position switch giving you the choice of 1-6, 9, or 12 stages of all pass filtering. Odd number stages are out of phase for a unique expressive tone. Lower stage counts act as tremolo or a notch filter. LFO, Envelope and Modulation Rate: Adjusts the sine wave modulation from imperceptibly slow to audio rate modulation depending on the Modulation switch setting.Amount: Adjust the amount of bi-directional LFO modulation in LFO mode or the start of modulation in Envelope mode. Modulation Switch: Up: Slow LFO from Show more
