DLS Effects RotoSIM
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 good ones out there), but something that would get me close to real rotary speaker sound, without me having to lug around another heavy cabinet. I wanted a unit that offered fine control over all the different aspects of an authentic Leslie speaker unit, and could give me stereo output, but didn’t sound canned. I found some good-sounding gear, but nothing really enticed me.

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

Rig Rundown: Adam Shoenfeld

Whether in the studio or on solo gigs, the Nashville session-guitar star holds a lotta cards, with guitars and amps for everything he’s dealt.

Adam Shoenfeld has helped shape the tone of modern country guitar. How? Well, the Nashville-based session star, producer, and frontman has played on hundreds of albums and 45 No. 1 country hits, starting with Jason Aldean’s “Hicktown,” since 2005. Plus, he’s found time for several bands of his own as well as the first studio album under his own name, All the Birds Sing, which drops January 28.

Diatonic sequences are powerful tools. Here’s how to use them wisely.



• Understand how to map out the neck in seven positions.
• Learn to combine legato and picking to create long phrases.
• Develop a smooth attack—even at high speeds.

Knowing how to function in different keys is crucial to improvising in any context. One path to fretboard mastery is learning how to move through positions across the neck. Even something as simple as a three-note-per-string major scale can offer loads of options when it’s time to step up and rip. I’m going to outline seven technical sequences, each one focusing on a position of a diatonic major scale. This should provide a fun workout for the fingers and hopefully inspire a few licks of your own.
