blackbox quicksilver delay price : $475.00

features:
separate short/long delay settings selectable on the fly via a stomp switch
variable bandwidth control over the delayed signal for brighter tape delay sounds or darker analog delay sounds
delay time modulation for fast vibratos, ring modulation effects, tape delay wow and flutter, chorusing and out of control pitch bend effects.
runaway feedback effects
effects loop for routing the delayed signal through external effects.
continuosly variable delay time for great divebomb pitch effects and delay time pitch bending madness
expression pedal control over delay time
1.2 seconds delay time
separate wet and delay mix outputs
true hard bypass switching
and yes, amazingly enough, it runs off a 9v battery! (and dc power too)

controls:
delay l - controls the longer range delay time setting
delay s - controls the shorter range (slapback) delay time setting
tone - controls the tone of the delayed signal. brighter for tape delay type sounds, darker for analog delay sounds.
mix - controls the delay signal level
wobble - controls the amount of modulation applied to the delay time
speed - controls the speed of modulation (fast for vibrato and ring mod effects, slower for tape delay wow and flutter)
repeats - controls the number of repeats. from one slapback to runaway feedback.
input gain trim - this is an internal trim pot for adjusting the input gain for the delay section only. it does not affect the dry signal gain. the quicksilver is factory adjusted for the largest amount of headroom with most guitar pickups. the input gain trim is located on the back of the circuit board through the hole in the topmost circuit board (located in the lower right hand corner of the circuit board as you are looking at it from the back of the quicksilver. if you are getting distortion or clipping in the delay section, adjust the input gain trim counter clockwise. to get more gain out of the delay section, adjust the input gain trim clockwise. adjusting the trim pot with the pedal powered up is not recommended. be careful not to force the trim pot or over adjust it or to touch the screw driver to other components or traces on the circuit board.
long/short switch - selects the long or short delay setting. the led indicators will light up to let you know which one is currently active. red for long, yellow for short.
bypass switch - bypasses the delay effect and routes your signal straight through for true bypass.

jacks:
in - effect input jack
out - effect output jack
loop/wet out - feedback effect loop output and 100% wet output.
loop in - effect loop input
exp - expression pedal input for control over delay time

suggested uses:
where do we start? there are way too many possible uses for this thing there is no possible way to list them all. here are a few to get you started on the road to delay heaven with the quicksilver.

effects loop:
the quicksilver allows you to process the delay feedback loop through external effects. to use the quicksilver with other effects or processors in the effects loop, refer to the diagram at right. connect the loop/wet output to the input of the first effect or device in the signal chain. chain together as many devices as you like and then connect the output of the last device in the signal chain back into the loop in. adjust the "repeats" knob for the desired regeneration level. now, every delay repeat will be routed through this signal chain. as the delays repeat, the signal becomes more and more processed as the audio is repeatedly routed through the same effect chain again and again. bypassing the quicksilver also bypasses anything in the quicksilver's effect loop. effects that create gain (overdrive, fuzz, etc.) will cause the quicksilver to feedback more quickly so back off on the repeats knob.



put a volume pedal in the feedback loop and turn the repeats all the way up. you can now control the repeats using the volume pedal. bring it all the way for runaway feedback delays and then roll the volume pedal back to bring it back under control. to really nail the tape delay sound, put a compressor (such as the blackbox oxygen) in the feedback effects loop of your quicksilver. turn the tone knob all the way clockwise, set the modulation speed all the way counter clockwise, set the modulation amount (wobble) to taste and voila. put an eq or filter in the feedback loop to tailor your delay tone to your liking. other suggestions for things to stick in the effects loop are: fuzzes (back down the repeats to avoid runaway feedback), tremolo, phasers, wah pedals, delays, and on and on. as the signal delays, it becomes more and more effected as the signal is repeatedly routed through the effects chain in the feedback effects loop.

expression pedal:
to control delay time using an external expression pedal, simply plug a standard expression pedal (a volume pedal will note work, make sure it has a stereo or trs plug) into the exp jack. set the delay time sweep range that the expression pedal travel will control using the front panel delay time control. important! do not plug audio cables into the exp jack!

other suggestions:
for ring modulation effects, turn the modulation speed all the way clockwise and turn up the wobble to taste.
for vibrato effects, set the modulation speed between 2-4:00 and turn up the wobble to taste.
for subtle chorusing effects, set the the speed between 11:00-1:00 and turn up the wobble just enough until you start to hear a slight pitch modulation.
for stereo delay, use the regular output and the loop/wet out in combination. you can turn the mix down to get a dry signal out of the regular output. the loop/wet out outputs a 100% wet delay signal.

unplugging the cord from the input jack when not in use will switch the quicksilver off and will prolong battery life significantly. when using the dc jack, use a 9v dc filtered and isolated power supply. tip negative, ring positive. we recommend using a dc power supply but if you need to use batteries, we recommend using long life alkaline batteries. low batteries or underpowered dc adapters may cause your quicksilver to function incorrectly. installing a fresh battery or using a higher amperage rated power supply will resolve this issue.
