The Seymour Duncan Mark Holcomb Dark Sun combines a warm and clean digital delay algorithm with a lush Hall reverb, and the ability to route the two in just about any configuration you could want. And, you can shape the EQ of the effect, add saturation, or lush choral modulation, or use Dynamic Expression to control the mix of the effect with your playing.
Mark wanted the ability to change the order of the effects on the fly and assign them to either the left or right channel – so we designed the routing control; a 4-position switch that can create dramatically different sounds depending on how it's set. Running delay first means new reverberations are created with each repeat – while putting reverb first will create a less natural and more dramatic repeat of the reverb trail. Setting Delay and Reverb to the left and right channels allows you to use Dark Sun’s two effects in stereo or as two separate pedals in one.
A complement of filters, gain, and modulation round out the feature set. Applied only to the wet signal, they can totally re-shape the character of the effect. Use the Low Pass Filter to soften and warm up the sound, or the High Pass Filter to cut big low-end repeats, allowing you to use high mix settings without overpowering your playing. Saturation adds gain for pleasant lo-fi effects, tape-like saturation, or shoegaze-style distorted repeats. And, the modulation section can be assigned to the delay, the reverb, or both. The pedal also has 4 tap divisions available – quarter notes, dotted eighths, eighths, and triplets.
