Alexander Pedals Radical Delay DX
What is the history of the Alexander Pedals Radical Delay DX? Well, we released the first Radical Delay pedal way back in 2015 as an homage to the tones and aesthetics of the 1980s. We were shooting for video games, neon nights, and maybe a hint of ALF.
It’s now 2019, and according to conventional wisdom, we should be fighting with replicants in the streets and competing in futuristic running-based game shows.
Since that stuff hasn’t quite happened yet, we thought it might be time to update the Radical Delay to our Neo Series platform and give it a bit of a makeover at the same time.
What’s new in the Alexander Radical Delay DX?
Inside you’ll find the same great delay and special effects that made the earlier Radical Delay pedals so fun, plus a few new twists. Outside, we’ve added some teal and chrome and intensified the laser grid for your enjoyment.
Controls
Radical Delay DX features six delay modes, all of which are adjustable to play from 24kHz down to 1.6kHz bandwidth using the CLOCK knob.
The maximum delay time varies by mode and clock rate, but it varies from 680ms to over 5000ms. Yep, that’s over 5 seconds of delay time, but it sounds terrible. It’s gross. Don’t say we didn’t warn you.
Each of the knobs on the Radical Delay DX has more than one function.
Turn the knob to adjust the main control, labeled in large text under the knob.
Hold the Select button and turn the knob to adjust the Alternate function, labeled in (parentheses) under the knob.
TIME
Adjusts the delay time. Available delay ranges from 0-1280ms in most modes at full audio quality and over 5000ms at computer barf quality.
ALT:
Controls a different parameter in each delay mode.
REPEATS:
Controls the delay feedback or repeats. The Radical Delay DX will self-oscillate or feed back forever if you want. Be careful with short delay times, the repeats get loud quickly!
CLOCK:
Here’s the magic.
This knob is tied directly to the clock oscillator for the delay engine. Turn it up for full bandwidth and highest processing speed, turn it down for longer delay times and lo-fi fun.
There’s a point where the internal clock circuit has a hard time working, and you’ll hear this as white noise in the output signal. We put it there because it sounds cool, but if you’d prefer less noise just crank this knob up a little. The clock knob will also totally bork the Tap Tempo timing, so if you need accuracy keep this knob full up.
MIX:
Controls the blend between the dry and delay signal. Equal mix is at approximately 3 o’clock, higher mix levels function as a “kill dry” with only a wet signal.
LEVEL:
Controls the overall output level of the pedal, from -20dB to +10dB. Unity gain is near 1 o’clock.
TWEAK:
Adjusts a different parameter in each delay mode. See below for full details. (RAMP RATE): Sets the speed at which the ramp generator morphs between settings.
Bypass and Option Foot switches
Both of the Radical Delay DX foot switches serve multiple functions, as you might expect. BYPASS / (PRESET): Tap this foot switch to bypass or engage the effect.
HOLD this foot switch to advance to the next preset.
TAP / (OPTION):
Tap this foot switch two or more times to set the tempo of the main delay effect. Please note that the tap tempo will be less accurate at lower Clock settings. If you need tight timing, crank that Clock full up!
HOLD this foot switch to activate the Option function.
If Option is configured for Tap Division, holding this foot switch will select the next tap division.
If Option is configured for Ramp, holding this foot switch will trigger the ramp generator and begin morphing to the other ramp setting.
BONUS: If Option is configured for Ramp, you may select the Tap Division by first holding Select and then holding this foot switch.
DELAY MODES:
MOD Digital delay with modulation. Tweak controls the mod depth and ALT controls the mod rate.
BEND Pitch shifted delay. Tweak selects the interval (-12, -7, -2, -1, detune, +1, +2, +3, +4, +5, +7, +12) and ALT puts the shift before or after the delay.
DUAL Dual-tap delay line. Tweak controls the delay time for the second tap and ALT controls its feedback.
REV. Tweak warps the delay from forward to reverse, with “tape stop” sounds available fin between. ALT mixes between the main reverse delay and a forward delay. Just want reverse? Set Mix, ALT, and Tweak to the maximum.
ARP Chiptune arpeggiator delay. Tweak controls the speed of the arpeggiation and ALT selects from 8 scale options.
DYNA Dynamic delay. The delay time sweeps with your picking attack. Tweak controls the sweep amount and direction, and ALT sets the volume sensitivity. Be careful with short delay times – that’s where the laser birds live.
