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-tweak-able 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
Buy if … you’re looking for a versatile, authentic-sounding rotary
effect with stereo output.
Skip if … you’ve got the roadies to haul your vintage Leslie cabs.
Seymour Duncan SFX-07 Shape Shifter
This tap tremolo was made to reproduce the rich classic tremolo
sound of vintage fifties tube amps, but the Shape Shifter also
offers new parameter controls to make your tremolo do things
those amps could never do—warble, sputter, flutter, even a helicopter chop. Some settings approach a filter effect vibe, and others even sound like delay.
