The Caline CP-505 Wave Machine is a chorus pedal, a modulation effect that splits your signal, detunes a copy of it and blends the two back together to produce a shimmering, widened tone. Pedal of the Day, reviewing it in August 2023, describes it as providing "lush, rich shimmering chorus" and says it is "based on a classic 1970's analogue circuit", placing it in the tradition of vintage chorus designs1. It sits alongside Caline's other modulation pedals, including the Caline CP-13 Super Chorus and the Caline G-003 Orca Chorus.
What it does
The Wave Machine takes a single guitar signal and produces the doubled, slightly detuned character that defines chorus. According to Pedal of the Day, it covers a wide range within that: "offering endless possibilities from a subtle watery sheen to full on psychedelic vibrato"1. At one end of its range it adds a light shimmer behind your core tone; pushed further, the modulation deepens into vibrato territory, where the pitch itself bends rather than simply doubling.
A Level control sets how much of the effected signal sits against your untouched tone. Pedal of the Day notes that "an added Level control lets you dial in the perfect amount of the effect to your dry signal", which matters for players who want the chorus felt rather than heard, or who need it to cut through in a band mix1.
What reviewers said
Pedal of the Day reviewed the Wave Machine on 4 August 2023, alongside the CP-506 Multimod, and came away favorable on both1:
"The Wave Machine and Multimod add gorgeous modulation to any rig, creating lush, vintage-sounding tones that ring out for days."
The reviewer's emphasis falls on vintage character: the 1970s analog circuit basis and the lush, ringing quality of the tones it produces. For a player comparing chorus pedals, that positions the Wave Machine as a traditional analog chorus rather than a modern digital multi-mode design, with the Level blend as its distinguishing extra control1.
