I spent some time this past summer looking around for a good Leslie-type effect for my stage rig—not a Uni-Vibe or something like that (although there are plenty of
Then the DLS RotoSIM came across my desk, and I have to say that while it didn’t light me on fire, it does have everything I was looking for—and a real shot at finding a spot on my pedalboard. For starters, it’s got individual horn intensity controls for Bass and Tweeter, independent rotation speed knobs, ramp time control and a footswitch to toggle between fast and slow settings—all necessary features in my book. In addition, there is a built-in overdrive with an On/Off switch and gain control. At high gain, the overdrive clipping is a little harsh for my taste, but it’s quite good if you just want to throw a bit of dirt in there.
Stereo output is also a must-have option for truly convincing Leslie swirl. The DLS’s stereo output feature goes even further, as it provides two separate inputs. Use the stereo input and get a lush, even spread from the dual outputs; or, use the other input and the two outputs then offer slightly different tonalities for you to choose from. In this setup, Output A is more transparent, as advertised. Output B is thicker sounding, and seems to have greater presence. If these or any of the other tonal elements don’t suit your liking, there are seven internal trim pots for extra-tweakable volume, gain, blend, response—everything. I played this unit through several different guitar/amp combinations, mono and stereo, and I was very pleased with the way it handled everything I did. – CB
