Asheville Music Tools – ACV-1, Analog Chorus & Vibrato
100% Analog BBD based Chorus Vibrato pedal
The Analoger™ Series ACV-1 chorus/vibrato/slapback is the latest creation in our series of 100% analog effects. The ACV-1 consists of a modulated BBD delay line with a flexible supporting cast of synthesizer-inspired controls. On the surface, the ACV-1 is simply a highly tweakable classic chorus. In reality, it is a veritable powerhouse of time warping modulation effects: shimmering comb filter swirls, luscious true pitch vibrato, glitchy textures, ringing metallic pipe tones, and even a faux reverb.
This astounding analog modulator was engineered by Hawker to deliver the ultimate time warping experience. With a bit of a mind flip, you’ll be into the time slip—and nothing will ever be the same!
Detailed Controls Overview
Time: Time: Delay time, adjustable from 3.1ms to 59ms. Expanded to 155ms with Expression pedal, control voltages, or LFO.
Feedback: lets you deepen the chorus effect and explore more exotic flange-like sounds. Dial in peaks and notches for resonant pipe/bell sounds, add to the wet feel of chorus sounds, or add deep vocal sounds.
Rate: LFO rate, from 0.1Hz to 14Hz (or faster with use of an Expression Pedal). Modulate your playing for even more sonic possibilities. From shimmery chorus/vibrato warbles to octave shifting and more, the LFO will take you to new sounds with real fractional delay modulation that can only be achieved by true analog delay.
Amount: LFO amount. Control the influence of the LFO on the delay, from light tone enhancing shimmers to mind-bending warbles! Unlike traditional choruses that use a linear modulation, we use an exponential modulator for smooth volt/octave time and frequency shifts that stay musical over the entire sweep range.
Mix: the blend between Wet (effected) and Dry (un-effected) signals. Capable of fully muting the dry signal, ideal for parallel effects loops or vibrato sounds.
Tone: Placed inside the feedback loop. Turn the control counterclockwise for the muted warmth or turn clockwise for a bright punchy chorus or flanging sounds.
Phase: sets phase of both the feedback and mix, thus shifting the notches and producing a deep hollow tone at short time settings.
Bucket Toggle: sets the time range. Use 2 buckets for longer delays, and use 1 bucket for slapback and faux chorus/flange sounds.
LFO toggle: sets the LFO waveform between triangle, sine or square wave. Triangle mode is perfect for classic modulated sounds, and sine works well for the smoother movement of vibratos. The square wave mode can produce musical pitch jumps or atonal chaos!
Bypass Footswitch: effect on/off. The internal switch selects between True Bypass and Buffered Bypass using a JFET buffer for a warm yet natural buffered sound.
Expression Switch: 4 position rotary switch lets you assign CV / Expression control to Time, Feedback, Rate, or Amount. Connect an external expression pedal (internal +5V supplied on ring) or a 0-5V CV input for even more range and control of your playing.
True Bypass / Buffered bypass: Internal slide switch. Select between true bypass (takes the ACV-1 entirely out of your signal path) or a classic JFET buffered bypass to prevent noise and signal loss in your effect chain.
