DL4 Stompbox Modeler FAQdl4 stompbox modeler pedal faq frequently asked questions
Q: Will the Stompbox Modelers work with other instruments besides guitar?
Yes, the Stomp Box Modelers will work with just about any "instrument level" device including bass guitar.
Q: How can I reset my DL4 to the factory presets?
A: You can reset your pedal to the factory settings by powering it up with the A and D footswitches held down - the power is turned on and off on the modeler pedals by inserting a plug into the left mono input jack.
Q: How can I set up my DL4 in an effects chain? What kind of power supply does the DL4 require?
A: For information on setting up your DL4 in an effects chain or power supply information, please click here.
Q: Does the DL4 have reverb?
A: The DL4 delay Modeler does not have reverb. It has 15 different delay models and a loop sampler.
Q: What are some features and functions of the looper?
A: The DL4 Loop Sampler function operates at 14 seconds to summed mono outputs at regular speed, and 28 seconds at half speed. A loop sampled and played at normal speed, then switched to half speed, will drop the pitch an octave. A loop sampled and played at half speed will play back at normal pitch. If the speed is then returned to normal, the pitch will be raised an octave.
When the DL4 is in 1/2 speed mode, the sampling rate and consequently the bandwidth have been halfed. This shouldn't be very noticeable though as this halfed bandwidth is still wider than most standard electric guitar amps. If you were using the unit with a very clean, bright electric guitar (or acoustic guitar)and monitoring through studio monitors, you may notice the change in bandwidth.
While in "Loop Sampler" mode, the DL4 will receive signal through each of its two inputs simultaneously. The input signal will then be summed to mono, sampled and then sent to the two outputs. In order to sample both inputs separately (or in stereo), the unit would have required two separate sample processors and a lot more RAM. Needless to say, this would have increased the cost of the unit dramatically. All other DL4 "Delay Models" will however have a discrete left and right stereo output.
Q: How can I use an EX-1 Expression pedal with my DL4?
A: For information on using an EX-1 expression pedal with the DL4, please click here.
Q: How is the Expression pedal implemented in the loop/sampler portion of the DL4? Can you adjust the feedback level of the loop (so loops start to fade), or just the mix of loop in the output signal?
A: The expression pedal works the same way in the Loop Sampler mode as it does in the regular delay mode. You can set the toe-down position of the pedal to one setting of the knobs (excluding the model selector knob) and the heel-down position to another setting. For example you could have the toe-down position set for the loop mix (mix knob) at maximum, the delay level (tweez) at medium, the delay modulation (tweak)at minimum, the delay repeats at half-way, and the delay time set fast (say 3 o'clock). You could then put the pedal in the heel-down position and set the knobs for the loop level at minimum, the delay level at maximum, the modulation at minimum, the repeats at minimum and the delay time long (say 9 o'clock). Now when you're playing (and the play/stop button is switched on), putting the pedal in the toe down position will give you the loop at full volume, pre-loop delay that is of medium volume volume with no modulation and a fast time. When you switch to heel-down, you'd get no loop (even with the play/stop button switched on)with a long single delay that is very loud. Yes it will remember your settings after you turn the DL4 off.
The loop sampler can either play the loop indefinitely (until you hit the stop button)or play it one time only then stop (Button C). It will not trail off on it's own. You would have to use the expression pedal to ride it's level.
Q: On the stomp-box modelers, how do I turn on the alternate (delay trails) bypass and what does it do?
A: Alternate Bypass will allow the delay to remain in the signal (fade off into the distance) when the pedal is turned off, where True Bypass will stop the delay as soon as the pedal is turned off. Alternate bypass mode should prevent any drop in volume level when the pedal is engaged. In addition, it will not cut off delay trails in a long delay setting.
To switch between true bypass and alternate bypass mode, you will need to hold down the a and c buttons at the same time for at least three seconds while inserting the left mono input(which will turn on the unit) to initialize alternate bypass. It will remember the selected bypass mode. Since it's a simple toggle, if you want to switch back, just repeat the process.
Q: I'm having a hard time getting my bass loops to sync up with my drum tracks. It almost sounds as though the bass loops are slowing down. Is that possible? Or are there some tricks to getting the loops right on the money?
A: What you are experiencing is caused by the fact that it is very difficult to record a perfectly timed loop. Even if the original loop is off by the slightest amount of time, that time will be compounded with every repeat of the loop.
Example: if the end of the loop is 1ms off, after 10 loops the guitar parts are now 10ms faster or slower than the drum parts. After 15 loops it will have a 15ms difference etc...You may need to re-sample the loop if after using it 6-8 times it doesn't match perfectly. With practice, you will get the feel of the correctly timed loop.
Q: Can I make the sampled loop louder without overpowering my guitar?
A: While in the LOOP SAMPLER mode, a simple turn of the MIX knob should enable you to control the level of the initial loops. Also, using the DL4 with a Line 6 EX-1 Expression Pedal will enable you to "morph" between two different MIX settings on the fly, from the floor, in real time. Simply place the EX-1 in the "heel down" position and program the pedal to your first desired setting. Next, put the EX-1 in the toe down position and program your second desired setting. Now, move the pedal back and forth and morph away baby!
More information on the DL4 can be found at our Stomp Box Modelers product page.
Q: What is the "suppressed carrier" frequency of the ring modulator patch? Is it fixed, or does it change with the variable waveform control (tweak or tweez)?
A: It is variable and controlled via the tweak knob. 0 = sine, 10 = square wave.
Q: How do I get the "Alvin Lee" dotted eighth note rhythm or "U2/Edge" delay from the DL4 pedal?
A: The Alvin Lee Dotted Eighth Note Rhythm:
The "Alvin Lee" sound is a single slap-back repeat. To set it up:
1. Tap the dotted eighth rhythm into the Digital Delay model.
2. Set Repeats, Tweak and Tweez to zero and the mix to 1:00. It may seem difficult to tap that rhythm in with your foot, but with a little practice, it becomes pretty easy. There is no preset delay value of a dotted eighth rhythm in the Rhythmic Delay model.
The "U2 / Edge" Delay:
The "U2/Edge" sound has 1.5 to 2 repeats on each of the stereo delays. To set this up:
1. Set the delay model to stereo delay and the unit automatically defaults to the "U2" sound. The Edge delay is actually a dotted eighth rhythm on the left side and a quarter note rhythm on the right side. The way to adjust the delay to this sound is to set the delay time to 11:00, repeats to 7:30, Tweak to 11:30, Tweez to 7:30 and mix to 1:00. If you want the tempo to be faster, just move the Delay Time and Tweak knobs a little counter-clockwise. You will have to make adjustments by ear to get that perfect "dotted eighth and quarter note" sound.
The default Tap Tempo rhythm for the models is a quarter note. It is not possible to change this default rhythm. The only solution would be to save the presets with a different rhythm. This would allow for six presets if you used the optional expression pedal.
