Asheville Music Tools ACV-1

Analoger Series ACV-1 100% Analog BBD Based Chorus / Vibrato Time Warper

Controls (specification subject to our tweaks/changes or the whims of our overlords)

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 sounds like a pipe or a bell, 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, or vibrato warbles to octave shifting and more the LFO will take your delay to new sounds with true fractional delay modulation that can only be achieved by true analog delays.

Amount: LFO amount. Control the influence of the LFO on the delay, from light tone enhancing shimmers to mind-bending warbles! Unlike traditional delays 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.

Tone: Placed inside the feedback loop, turn the controls 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 shifting the notches and producing a deep hollow town at short time settings.

LFO toggle: sets the LFO waveform between triangle, sine or square wave. Triangle waves are perfect for classic modulated sounds, sine for the smoother movement of vibratos and square wave can produce musical pitch jumps or atonal chaos.

Bypass Footswitch: effect on/off - 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 control the Time, Feedback, Rate or Amount with 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: Select between true bypass (takes the ACV-1 entirely out of your signal path) or a classic JFET buffered bypass to give drive and keep your signal chain from undesirable tone suck, noise and signal loss.

• Type: 100% Analog signal and control path

• Bypass Footswitch: effect on/off user selectable True Bypass or JFET Buffered (Accessible by removing ACV-1 Cover)

• Power: 9VDC @ <150mA. 70-90mA typical. Up to 250mA start up. Standard pedal center negative 2.1mm x 5.5mm barrel.

• Delay Time: 3.1ms - 59ms. 1.9ms - 95ms with LFO and to 155mS with external Control Voltages

• Feedback: 0 to near infinite. Capable of self-oscillation using tone or EXP input coupled with knob position.

• Rate: LFO RATE, from 0.1Hz to 14Hz (28Hz with CV control)

• Amount: LFO depth control from OFF to 60% of TIME sweep

• Mix: Center 50%. Adjust from full wet to full dry

• Tone: ~740Hz center tilt filter. Center = Flat to 0.3dB

  High +5dB to -10dB, Low +4dB to -7dB.

• Phase Switch: 180° phase shift of wet signal and feedback signal.

• LFO: Selectable Triangle, Sine or slewed Square wave

• Expression Switch: 4 position rotary selects Time, Feedback, Rate or Amount external control. All controls are additive to the front panel knob adding extended range. TRS jack usable with CV or Expression pedal, (CV range is 0-5V). Ring supplied current limited 5V output. Control input on Tip.
