DYNAMIC
Based on* the TC Electronic 2290 Dynamic Digital Delay.
This is a sort of “smart” volume control for your delay effect’s echoes, which automatically sets the loudness of the delay repeats based on how
hard you play. While you’re playing, the Dynamic Delay keeps the volume of the repeats turned down, so that they don’t overwhelm what you’re
doing. Then, when you stop playing for a moment, the volume level of the repeats turns up to allow the repeats to be heard.
The TWEAK knob sets the Threshold—as your input signal is analyzed, this is the breakpoint where this automatic volume control stops working and lets the delay repeats through at
full volume. The TWEEZ knob adjusts the level of the “ducked” repeats—higher settings will reduce the delay level down more aggressively. Try setting TWEAK and TWEEZ to around
50%, and hear how the delay effect gets partially muted while you play, helping to avoid that unwanted “muddy” sound.
TWEAK adjusts the Threshold from -20dB to -60dB.
TWEEZ adjusts the Ducking from 0 to -138dB
AUTO VOL
A Line 6 original.
This model gives you two effects in one. The Auto-Volume part of the equation is a volume fade-in swell, like the attack time on a synthesizer’s envelope
generator. Since, unlike other effects in DL4 MkII, the swell affects your dry signal, this can be used for a bowing effect, like the one you get by turning the volume knob on your guitar
quickly up from zero just after you pick a note. Higher settings for the TWEEZ knob will give you a longer swell time, so that the sound slowly fades in, like a wave.
The other effect is an echo, complete with tape-style wow & flutter modulation goodness, adjustable via the TWEAK knob.
TWEAK sets Modulation Depth from 0% to 100%.
TWEEZ sets Ramp Time for the auto-volume swell. Range: 0.030-1.900 seconds
TUBE ECHO
Based on* the 1963 Maestro EP-1
This Maestro unit was the first of a series of “Echoplex” designs distributed by the company and made by Harris-Teller in Chicago. As touted in a Maestro
advertisement, the Echoplex’s “...special effects range all the way from a controlled high speed reverberation to a full, throbbing echo!”
The Echoplex design centers on a special cartridge of looped 1/4" tape that wraps past separate record and playback heads. The position of the playback head
can be moved to adjust the delay time from 60 to 650 milliseconds. Your DL4 MkII’s Tube Echo emulates the classic Echoplex tone with the extra advantage
of up to 2.57 seconds of delay time (and you’ll never need to buy new tape cartridges!).
TWEAK adjusts the emulated tape’s Wow and Flutter from 0-100%
TWEEZ adjusts Drive, which is the amount of distortion created by the unit’s tube electronics and tape saturation.
