The Warm Audio WA-C1 dual-pedal brings back the sound of vintage chorus and vibrato boxes before adding some modern perks on the side. This tank also features a 100% analogue preamp and a dedicated vibrato section, which can be dialled in to shape the warm and full sound that helped make legends like The Police and Queen. Accurately tweak the output via the Rate and Depth control pots and pull the effect from a subtle modulation to a deeper, more choppy wave-like effect. The Warm Audio WA-C1: One Step Beyond This pedal is home to a MN3007 Xvive BBD chip: the same one that was responsible for the rich mids and warm analogue modulation delivered by the vintage chorus pedals we all know and love. Beyond that, the WA-C1 is far more flexible than any antique model, so a set of Rate and Depth pots for moulding and shaping the chorus are supplied so you can get as discrete or bombastic as you want. Meanwhile, the high-sensitivity mode adds some clarity and headroom to the mix, broadening the sonic range. Vintage Sound + Modern Design Everything comes wrapped in a solid stompable box fitted with LED indicators to ease effect monitoring, making the WA-C1 the perfect blend of vintage sound and modern ease. The range is also pretty astounding, from warm and earthy '70s-era chorus to the bright and high-amped tone of an '80s chorus - all with a big dollop of vibrato on the side - it's all here.
