Deep Dive into the Effects of the POD HD Multi-Effects Processors: Dynamic Delay

The Dynamic Delay effect in the POD HD multi-effects processors is, in my opinion, the cleanest sounding digital delay model in the entire device. It should be. It’s inspired by* the famous T.C. Electronic® 2290 Dynamic Digital Delay, a true industry standard in the music world throughout the late 80s into the 90s and even today.

Brief History of T.C. Electronic®
T.C. Electronic® was born in 1976. A Danish company, it was the brainchild of brothers Kim and John Rishøj. During the early years, the company focused on developing guitar effect pedals but eventually branched out into the rack-mounted effects products world. Jump ahead to 2002 where T.C. Electronic® became the T.C. Group® after acquiring several smaller musical instrument companies including TC-Helicon®, makers of various harmony effects and vocal processors.

Some New Parameters
The Dynamic Delay effect model has many of the same tweakable parameters as the other traditional analog and digital delay effects in the POD HD multi-effects processors. Mix, Feedback, and Time are all in there. However, we are introduced to a couple of new parameters you may not normally see in other more “traditional” delay effect models.

Ducking: Depending on how you play, echo effects can sound cluttered and, well, not very defined. The Ducking parameter will actually force your repeats to “duck” (volume wise) below the next incoming guitar signal and then bounce back up once that signal has passed. Pretty cool!

Threshold: The Threshold parameter works in tandem with the Ducking parameter. Basically, you set this parameter to tell the effect to duck only when the input signal is a certain strength. If the signal doesn’t reach that strength, the delay will not duck.

If you’ve been following my blogs about the FX in the POD HD multi-effects processors you’re familiar with the fact that I always post a few tones on Custom Tone for you all to check out. This week is no different except now I’ve added sound clips as well! You guys asked so you shall receive!


The Dynamic Delay effect model allows you to dial in great slap back delay tones. I’d venture to say this slap back tone sounds almost as good as some of the other slap back delays I dialed in using the Analog Echo and Tube and Tape Echo models. I’m using the Blackface Dbl Nrm amp model here as it’s one of my favorite models and really makes the slap back tone come alive.



The Divide 9/15 amp model is capable of generating some great crunch tones similar to what you might here on various punk rock albums. I added a touch of Dynamic Delay to this tone to bring it all together.



Here’s something a little heavier for you high-gain folks out there. I’m using the Treadplate amp model here. You might hear a tone like this on some of the more modern punk rock albums, i.e. NOFX, Less Than Jake, etc. It would also work well for metal. I added only a touch of the Dynamic Delay model to give it more of a reverb- type quality as opposed to a true delay sound.



I love the little Super O model on the POD HD multi-effects processors. If you’ve been reading my blogs you already know this. This particular amp model breaks up beautifully when you drive it and in my opinion, is very easy to dial in. This tone highlights the Ducking and Threshold parameters on the Dynamic Delay effect model. When I attack a note you can hear the delay duck a bit. This would be a good tone for a softer intro in a song, right before it explodes!


Next time we’ll talk a bit about the Stereo Delay model which is perfect for high gain tones to create huge 80’s hair band tones. Fun!
