A Legacy of MidsIn the past decade, the Tube Screamer has continued to evolve with new editions such as the TS7 Tone-Lok, the TS808 reissue, the TS9B—the first Tube Screamer for bass—and the 2010 introduction of the Tube Screamer amp—an ultra-portable, low-wattage amp (available in head and combo versions) that incorporates a selectable Tube Screamer circuit in its preamp. So far, 15-watt head and combo models are available, although models with varying wattages are rumored to be in the works.

Despite the Tube Screamer’s many variations, Ibanez electronics merchandiser Frank Facciolo says its legendary sound is rooted in its characteristic midrange presence. Lomas agrees. “It’s still one of the best things to overdrive any tube amplifier with,” he says. “It just does magical things to tubes.”
