The reason is simple; DLS Effects™ is all about the ultimate in sound quality, feature rich products, and ultra quality construction.

DLS Effects™ are custom high quality effects designed by engineers who are also musicians. These effects were designed for the professional musician looking for fabulous sounds, extreme warmth, great versatility, robust construction, and great value!

We give the musician the controls to dial in the sound they are after while still keeping your natural instrument sound intact. These effects are also quiet.

Our effects are all constructed and manufactured in the USA using extra-heavy gauge steel enclosures, steel pots, and steel switches to withstand the roughest road environments. Plus, we use powder coating instead of painting for extra durability and a first class finish.

Product Highlight: After nearly 2 years of R&D, our beta testers all gave us a thumbs up to produce this unit, and believe me they are tough to please! Forget lugging around a rotary speaker cabinet any longer. The RotoSIM™ has all the controls and versatility any musician would need to get the rotary speaker sound you desire.
