The Abyss Bass Overdrive by KHDK Electronics is a game-changing pedal designed specifically for bass players seeking full control over their sound. It features a unique mix control system with separate volume adjustments for the original amp tone and the overdriven tone. The pedal utilizes bi-amp technology with two discrete circuits, allowing for the division of the signal into two paths. One path retains the dynamic and color of the original signal, while the other adds an overdriven sound with fullness and punch. When the two circuits reconnect, the result is a more powerful, fuller, and richer original sound.
Key Controls:
- DIRTY: Controls the amount of distorted signal in the tone.
- CLEAN: Adjusts the volume of the original sound without altering its
characteristics.
- TREBLE: Acts as a passive, natural-sounding low-pass filter with a wide
frequency range.
- LO/HI: Offers two settings - "lo" for a warm, tube-like boost and subtle
crunchy overdrive, and "hi" for added saturation, sustain, low-end, and
compression.
- GAIN: Sets the preamp gain, affecting the amount of compression and
sustain.
Power:
The Abyss operates on a single 9V battery or an external 9V DC (center
negative) power supply.
Specifications:
- Bypass mode: True Bypass
- Dimensions: 120 x 65 x 40 mm deep (Width x Depth x Height)
- Input Connector: Standard ¼” jack – mono/TS
- Output Connector: Standard ¼” jack – mono/TS
- Power Input: Standard 9V Battery or 9V DC (center negative) power supply
The Abyss Bass Overdrive is known for its versatility, offering a wide range of tones suitable for various genres, from mild overdriven boosts to full, always-on distortion, making it a valuable addition to any bass player's setup.
