Asheville Music Tools ACV-1

ACV-1 Time Warping 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! At the heart of every chorus is a short delay whose time is modulated by a low frequency oscillator (LFO). The ACV-1 uses a 1024-stage X-Vive™ high-voltage MN3007 BBD chip for its delay line. Mixing that delay back in with the original signal produces the familiar, lush sound of chorused voices in unison. Many choruses keep the delay time fixed, but our Time knob lets you warp through the decades of chorus. Start in the middle for a tight 70’s-style chorus. Go longer for a drippy 80’s chorus and a warm slap delay, or go shorter for flanging tones. Another uncommon addition is our Feedback knob with phase options. This lets you deepen the chorus effect and explore more exotic metallic or vocal sounds. At high feedback settings you can use the Time knob to dial in peaks and notches for resonant sounds, like a pipe or a bell. The Tone control changes the frequency response of the feedback loop to make your chorus more shimmery, or more dark and haunting. Utilizing the phase switch you can produce hollow, deep vocal sounds akin to a talk box. Our LFO includes multiple waveforms: triangle for classic chorus sounds, sine for gooey vibrato, and square wave for rhythmic glitches and pitch jumps. The Rate and Amount controls have a huge range from subtle dimension to complete time warping madness. Or you can zero out the LFO to explore double-tracking effects, static comb filtering, and short delay. The Mix control has a range from fully off to 100% wet, which lets you dial in subtle sounds or go all-in for true analog pitch vibrato. These settings are great for Leslie organ sounds or tape-like warble. The Tone control is even more useful here, as a way to sculpt the overall tone of your wet signal. Finally, the CV jack rewards more intrepid sonic explorers with an even wider range of control. Increase the feedback into self-oscillation, push the LFO beyond its limit to audio rates, or drop the delay time into a lo-fi, ring-modulated soundscape. With its thoroughly engineered set of features, the ACV-1 synthesizes decades of time warping modulation effects to inspire a whole new dimension of sounds. Features: -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. -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 switch: 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. description Manual Needs: 9VDC 250mA Center Negative
