Though the compressor on the Tumbleweed is first-class, it’s the boost function—and the ability to use them together—that really sets the pedal apart. Using the same settings and setups I used for the Telecaster and McGuinn tests, I used the boost and attentive use of the guitars’ volume controls to lend more girth, attack, and—with the guitar volume maxed—a range of higher-gain tones that resulted in a controlled harmonic bloom or a very musical and manageable feedback.
