Description
Most chorus pedals are designed with electric guitars in mind, which means acoustic players routinely lose tone and level running through an unbalanced input. The Rivera Acoustic Shaman fixes that: it’s a balanced-or-unbalanced input analog Chorus/Vibrato pedal built ground-up for acoustic-electric signal chains, and it’s the only chorus pedal specifically optimized for Taylor’s balanced ES pickup output. Feed it an unbalanced signal on any other pedal and you’re leaving up to 6dB of level – and a chunk of your guitar’s real tone – on the table.
Under the hood you get two independent LFO sections, so chorus sweep and vibrato warble can be dialed in separately rather than fighting over one rate/depth control. A three-position Mode switch moves between distinct Chorus and Vibrato voicings, while a 2-band EQ lets you push shimmer or warmth depending on the guitar and room. The Ef.Blend knob dials the wet signal in precisely rather than forcing an all-or-nothing mix, and the pedal runs equally well in stereo or mono setups.
Rivera builds the Acoustic Shaman with the same parts-bin discipline found in their amp circuits: WIMA polypropylene capacitors, Analog Devices OP275 op-amps, discrete low-noise FET and bipolar transistors, film resistors, and metal barrel jacks throughout. It’s the descendant of the modified chorus circuits Rivera has been refining for over 35 years – the same lineage heard on records by Supertramp and Larry Carlton – now reworked specifically for low-noise, wide-dynamic-range acoustic use.
