A Powerful and Sensibly Sized Wah Adds Fire to Your Filter Sweeps

The PG Morley 20/20 Wah Boost Review.



Compact, smartly sized footprint. Sweet sweep. Switchless operation.

No independent boost switch. Spring-loaded pedal makes set-and-forget parked-wah sounds difficult.


Morley 20/20 Wah Boost


Ease of Use:



Morley’s original chrome optical wahs were amazing pedals. Not only were they beautiful (and freaking big), they produced some pretty fantastic tones. I used an original Power Wah Boost for a long time. The optical wah was super-easy to control and had a long throw that made really precise colorations possible. The boost, meanwhile, was amp-bustingly monstrous. The new Morley 20/20 Wah Boost re-imagines the Power Wah Boost as a more compact pedal, but it makes a few design trade-offs that affect its versatility. It lacks the original's independent boost bypass switch, but makes activating the boost and wah together an easier one-step process. The spring-loaded treadle also makes holding fixed wah positions difficult. Still, it is a potent and expressive filtering machine.

The new Morley 20/20 Wah Boost re-imagines the Power Wah Boost as a more compact pedal.

If you’ve never used a Morley wah before, they are a joy. The treadle sweep is longer, with a more tapered filter curve than the average Cry Baby or Vox, and the optical circuit tends to produce more vocal, vowel-y filter sweeps. It’s a nice, if subtle, shift from classic, canonical wah tones. When used with a twitchy toe, it produces tones much closer to an envelope filter. And while the 20 dB boost cannot be operated independently of the wah, its ability to foreground the wah’s lovely tones for a solo—or tuck it in the background for softer passages—makes this mini-Morley a deceptively big bag of tricks.

This rare English Tonemaster was made circa 1957.

The Valco-produced English Tonemaster is a rare, lap-steel-inspired gem from the 1950s—when genres and guitar design were fluid.

The 1950s were a peculiar time for the electric guitar. Innovators, designers, and tinkerers were pushing the boundaries of the instrument, while musicians were experimenting with various playing techniques and sounds. There was an evolution of sorts (or de-evolution, depending on your slant) from solidbody “sit-down” guitars, like pedal and lap steels, to “stand-up” or “upright” solidbody electrics. If you look at an early Fender catalog—let’s say from 1953—you’ll see the Telecaster (and Esquire), the Precision Bass, and then a whole bunch of steel guitars. There was a shift underway, and many manufacturers began to blur the lines of what a guitar should look, sound, and play like.
