Used Universal Audio UAFX Del-Verb

The Universal Audio Del-Verb Ambience Companion is a high-quality, dual-engine effects pedal that brings together Universal Audio's acclaimed reverb and delay algorithms from their individual UAFX Golden Reverberator and Starlight Echo Station pedals into a single, compact unit. It's designed for guitarists (and other musicians) who want studio-grade ambient effects with intuitive controls and vintage authenticity.

Here's a detailed description:

Core Concept and Philosophy:

• "Desert Island" Reverbs and Delays: The Del-Verb is curated to offer three "go-to" reverb and three "go-to" delay sounds, aiming to cover a wide range of classic ambience needs without overwhelming the user with endless options.
• Award-Winning UAFX Engines: It leverages the same powerful dual-engine UAFX processing found in its larger, single-effect brethren. This allows it to run separate, stereo instances of both the reverb and delay simultaneously, creating lush and immersive three-dimensional soundscapes.
• Sonic Authenticity: Universal Audio is renowned for its meticulous digital emulations of classic analog hardware. The Del-Verb aims to deliver the sonic character and nuances of the original units it models.

Reverb Section: The Del-Verb features three distinct reverb algorithms, drawn directly from the UAFX Golden Reverberator:

1. '60s Spring: Emulates the tube-driven spring reverb tanks found in classic American guitar amplifiers (like Fender Blackface amps). It's known for its drippy, splashy, and vibrant character, perfect for surf, rockabilly, and classic rock.
2. Plate: Recreates the sound of a vintage German plate reverb unit (likely an EMT 140). This type of reverb is prized for its smooth, dense, and slightly dark character, often heard on classic vocal and guitar recordings.
3. '80s Digital Hall: Inspired by early digital studio reverb units from the 1980s (such as the Lexicon 224). This provides a lush, clear, and spacious hall reverb sound, excellent for ambient textures, soaring leads, and creating a sense of grand space.

Delay Section: The delay side of the Del-Verb draws its algorithms from the UAFX Starlight Echo Station:

1. '70s Tape Echo (Maestro EP-III): Emulates the iconic Maestro Echoplex EP-III tape echo, including its warm, slightly gritty repeats and the characteristic wow and flutter of a real tape machine. It's great for vintage slapback, rhythmic echoes, and psychedelic textures.
   • Color Knob: Adjusts the tape record level, allowing for saturation and mild overdrive.
   • Mod Knob: Changes the "tape type," from new/clean tape to older/worn tape, affecting the warmth and warble.
2. Analog Delay (Electro-Harmonix Memory Man): Recreates the thick, colored, and somewhat dark repeats of a classic bucket-brigade analog delay (like the EHX Deluxe Memory Man). It's known for its organic decay and ability to self-oscillate musically.
   • Color Knob: Adjusts the input gain to the delay circuit.
   • Mod Knob: Controls modulation type (vibrato below noon, chorus above noon).
3. Precision Delay (UA Original): This is Universal Audio's own pristine, studio-grade digital delay. It offers clean, high-fidelity repeats with dynamic and inspiring modulation options, suitable for modern ambient sounds, rhythmic delays, and pristine echoes.
   • Color Knob: Acts as a tone control for the delay repeats (darker to brighter).
   • Mod Knob: Controls modulation type (flanger below noon, chorus above noon).

Controls and Functionality:

• Dedicated Knobs: Each effect section (Reverb and Delay) has its own set of intuitive knobs:
  • Reverb Side: A single large Reverb knob controls the wet/dry mix for the selected reverb type. A three-way toggle switch selects between Spring, Plate, and Hall reverbs.
  • Delay Side: Time, Feedback, Mix, Color, and Mod knobs. A three-way toggle switch selects between Tape, Analog, and Precision delays.
• Dual Footswitches: Two footswitches can be configured for different functions via the UAFX Control app:
  • Default: Left footswitch toggles Delay on/off, Right footswitch toggles Reverb on/off.
  • Alternate Modes: Includes an "Effects | Tap Tempo" mode where the left footswitch toggles both effects on/off, and the right footswitch becomes a tap tempo for the delay. There's also a "Delay | Tap Tempo" mode where the left controls delay, the right is tap tempo, and reverb is always on (controlled by its knob). This limitation regarding simultaneous tap tempo and independent reverb bypass is a common point of discussion among users.
• Stereo I/O: Features dual 1/4" TS inputs and outputs for full stereo operation, allowing for expansive soundscapes. It also offers analog dry-through to preserve your core guitar tone.
• Buffered Bypass: Maintains signal integrity over long cable runs.
• UAFX Control App (Bluetooth): This is a key part of the UAFX ecosystem. Via a Bluetooth connection to your smartphone or tablet, the app allows for:
  • Tap Tempo: Enables tap tempo for the delay (as mentioned above, depending on footswitch mode).
  • Custom Voicings: Download additional "voicings" for each effect, which are essentially curated presets or variations that expand the sonic palette beyond the physical knobs.
  • Firmware Updates: Keeps the pedal up-to-date with the latest features and bug fixes.
  • Settings Adjustment: Fine-tune certain parameters not directly on the pedal.
• USB-C Port: For connecting to a computer for firmware updates and app communication.
• Power: Requires an isolated 9V DC power supply (not included) with a minimum of 400mA, center-negative.
