TECH 21, THE COMPANY
Tech 21 was formed by a guitarist possessing the unusual combination of a trained ear and electronics expertise. In 1989, B.Andrew Barta made his invention commercially available to players and studios around the world. His highly-acclaimed SansAmp™ pioneered Tube Amplifier Emulation in professional applications for recording direct and performing live, and created an entirely new category of signal processing.There have since been many entries into this niche, yet SansAmp continues to maintain its reputation as the industry standard.
With a full line of SansAmp models,Tech 21 also offers effect pedals and MIDI products, as well as “traditional” style amplifiers for guitar and bass. Each product is thoughtfully and respectfully designed by B.Andrew Barta himself with the player in mind. Our goal is to provide you with flexible, versatile tools to cultivate, control, refine and redefine your own individual sound.Tech 21 takes great pride in delivering consistent quality sound, studio to studio, club to club, arena to arena.
PRODUCT OVERVIEW
The Boost D.L.A. is an analog delay emulator pedal that uniquely incorporates a clean boost function for up to 9dB of additional volume.With boost and delay in a single pedal, your solos will jump out with greater dimension.
This pedal is designed with user-tweakable,“lo-fi” analog technology. By manipulating the controls, you can infuse degrees of warmth and life characteristic of vintage delays.The circuitry intentionally injects the inherent imperfections of vintage delays, which is what makes them so seductive and nostalgic.
A single, continuously-variable Time control provides a full sweep of delay, up to 1000 milliseconds. Flutter introduces modulation which adds a slight shimmering/chorus-like effect of a vintage tape echo.The Mix, Feedback,Tone and Level controls are 100% analog for warm, organic sounds.The Boost D.L.A. enables you to explore and custom tailor such delay styles as digital, vintage tape and bucket brigade.
As with each Tech 21 product, the controls are designed to give you the flexibility to obtain your desired sound. It is our hope that the Boost D.L.A. will be a useful tool for stimulating your creativity and, ultimately, providing the inspiration to play your best.
THE INS AND OUTS
1/4” INPUT: 1megOhm high impedance input, same as traditional tube amps.Also switches battery power on/off.To avoid battery drain, unplug when unit is not in use.
1/4” OUTPUT: 1kOhm low impedance output drives long cables without loss of signal integrity, even in bypass.
SIGNAL LEVEL TO INPUT/CONNECTIONS
The Boost D.L.A. is designed to accommodate instrument level signals to the Input, such as the output of a guitar, the output of distortion pedals, etc. For normal operation, signal level to Input should be close to that of a standard electric guitar (approx -10dBm / 250mV).
NOTE: Some amplifier effects loops are line level, which will cause the Boost D.L.A. to distort. It will also compress the signal and reduce the output.The same may hold true for mixing boards. Therefore, you may need to obtain a level matching transformer.
Be aware that line level signals will not damage the Boost D.L.A., however the resulting sound may not be particularly desirable.
GUIDE TO CONTROLS
TIME
Controls the amount of delay.This single, continuously-variable control provides a smooth, full sweep, ranging from 30 milliseconds up to 1,000 milliseconds.At 12 o’clock,Time is approximately 300 milliseconds.You can easily dial in the exact amount of delay desired with one turn of the knob.Turning the Time control while playing will transpose the pitch of your guitar note, just like a vintage analog delay.
TONE
100% analog shelving filter of 6dB per octave. Effects the tone of the delayed signal.At maximum (5 o’clock), it has no effect on the signal of the delay.As you decrease the setting, it will reduce the high-end to round off the signal and add warmth. So that, like an analog echo, each successive repeat will be darker.
Tone Tips: To slightly warm up the sound, experiment between 1-3 o’clock.To radically darken the tone, experiment between 12-7 o’clock.
With the Boost D.L.A. in front of a distorted or slightly distorted amp, set the Tone control to make the repeats darker than the straight signal, between 11-1 o’clock.This will keep the straight and delayed signal from “fighting” with each other.
FEEDBACK
100% analog circuit. Feeds back the delayed signal to the input of the pedal to generate the number of repeats.At minimum (7 o’clock), you will hear one repeat.As you increase the setting, the repeats will follow accordingly until they are almost infinite.
Feedback Tip: With the Boost D.L.A. in front of an amp, the amp will compress the signal and make the low level repeats louder.Therefore you will most likely need to have the setting lower than you would when running through an effects loop. For instance, you may find a Feedback setting at 10-11 o’clock through an effects loop will yield 3-4 repeats. However, through the front of an amp, you may find a setting of 4 o’clock will yield the equivalent.
MIX
100% analog circuit.Adjusts the ratio of direct and delayed signal.While most delay pedals provide a maximum 50/50 mix ratio via a level control, the Tech 21 Mix control offers a sweep from 100% dry to 100% wet.This gives you more flexibility when you want to run through a parallel effects loop without annoying phase cancellation, and to make the delayed signal louder than the direct signal for special effect.
FLUTTER
Introduces modulation which adds a slight shimmering/chorus-like effect of a vintage tape echo.At minimum (7 o’clock), there is no effect.At maximum, there will be a drastic shifting of the pitch, which can be used for extreme special effects.
