Put 21 different reverb effects under your feet with the BOSS RV-500 pedal, intended primarily for electric guitar. Rooms, halls, plates, springs, it’s all here, alongside more esoteric processes, such as octavized shimmering, as well as the characterful Lo-Fi, Slowverb, and Storm. Classic Roland units have also been emulated, such as Space Echo (the RE-201), and SRV, based on the SRV-2000, a popular unit in the 1980s. The RV-500 provides its sound using 32-bit AD/DA conversion, 32-bit floating-point processing, and sampling rates of 96 kHz. With a panoply of parameters in every effects type, you’ll be able to control your tone to an extensive and deep degree. In addition to dedicated panel knobs for pre-delay, effect level, and tone, you’ll also be able to perform extensive editing via the LCD screen and quadrumvirate of push-buttons. A tap tempo/control footswitch offers more in the way of on-the-fly manipulation. A and B footswitches not only provide bank selection tools—they also give you the ability to engage two reverb as once in a variety of modes (series, parallel, and parallel to different amps/destinations come to mind). In terms of I/O, the RV-500 gives you a bevy of possibilities, what with its dual inputs for stereo instruments, dual outputs, expression/control jack, and MIDI I/O. All in all, you’ll find 297 built-in patch memories in the unit itself, though you can also interface via USB with Editor/Librarian software on your computer for remote editing, storing your custom patches, and more. This pedal runs on four AA batteries, or by means of a power adapter, available separately. A/B Simul Mode and Independent Delay By means of its DSP engine, the RV-500's Dual mode provides two independent reverbs at once; you can feed them both with a full-range input, or with divided frequency ranges on each input to build rich, multi-range sounds. And when you employ A/B Simul mode, you can use any two RV-500 reverb patches at the same time, with your choice of series or parallel connection order and mixed or split A/B output. What's more, each patch also includes a digital delay with a full set of parameters including modulation and EQ, plus the ability to set the reverb and delay effects for series or parallel operation on a per-patch basis. Intensive Real-Time Control The RV-500 offers freely assignable switches and extensive real-time controls. By default, the A, B, and TAP/CTL switches offer control for patch/bank selection and bypass, plus tap tempo or real-time adjustment of one or more parameters. However, the switches can be customized to access three different mod patches, A/B Simul mode, and other functions. Via the rear-panel CTL 1,2/EXP jack, you can plug in up to two footswitches for further control, or an expression pedal to adjust wah, effect rate, and other parameters. MIDI I/O is also included, enabling further creative possibilities with advanced setups. Key Features at a Glance
