The Boost D.L.A. by Tech 21 is an analog delay emulator pedal that uniquely incorporates a clean boost function for up to 9dB of additional volume. The pedal is designed with user-tweakable, "lo-fi" analog technology, intentionally injecting the inherent imperfections of vintage units, which is what makes them seductive and nostalgic. It features a single, continuously- variable Time control providing a full sweep of delay, up to 1000 milliseconds, and parameters engineered to explore and custom tailor delay styles such as digital, vintage tape, and bucket brigade.
Key Features:
- Uniquely combines delay and clean boost, up to 9dB, in one pedal
- Custom tailor a wide variety of delay styles, such as digital, tape, and
bucket brigade
- Highly sensitive controls provide a broader range of tweakability and
maximum flexibility
- 100% analog Mix, Feedback, Tone, and Level controls for warm, organic
sounds
- Up to 1000 milliseconds of continuously-variable delay time
- Flutter introduces modulation which adds a slight shimmering/chorus-like
effect of a vintage tape echo
- Mix control ranges from 100% dry to 100% wet
- 1megOhm high-impedance 1/4” input, same as traditional tube amplifiers
- 1kOhm low-impedance 1/4” output drives long cables without loss of signal
integrity, even in bypass
- Custom, silent-switching actuator
- Buffered bypass eliminates the shortcomings associated with “true bypass”
- Heavy-duty, all-metal construction
- Operable with 9V alkaline battery (not included) or optional DC power
supply (Tech 21 Model #DC2)
The Boost D.L.A. is designed to accommodate instrument-level signals and is recommended to be placed last in the signal chain for optimal performance. The pedal also features a dedicated footswitch for Tap Tempo, allowing coordination with the drummer, and a Trails function that allows the natural decay of the delay signal rather than cutting it off abruptly.
The Boost D.L.A. is a versatile pedal suitable for various musical styles and performance settings, offering intuitive controls in a compact, durable design.
