Reverb Pedal: A Complete Buyer's Guide

Buying a reverb pedal means deciding whether you want a single, focused reverb sound or a multi-algorithm reverb pedal unit with presets, expression control and MIDI integration. It also means understanding power draw, physical size, and how the reverb pedal will sit in your signal chain. The right reverb pedal choice depends on your setup, your playing style and your budget.

Single-Purpose vs Multi-Reverb Pedal Options

A single-purpose reverb pedal does one reverb type—spring, plate, hall or whatever—and does it well. These are usually smaller, cheaper and simpler to operate. They're ideal if you know exactly what reverb sound you want and you're not going to change your mind on stage. Classic examples include the Boss RV-3 or the Electro-Harmonix Holy Grail, reverb pedal units that have been around for years because they sound good and they work.

Multi-algorithm reverb pedals offer several reverb types in one unit, often with presets so you can switch sounds instantly. They take up more board space and cost more, but if you play different genres or want options without swapping your reverb pedal, they're worth considering. The Strymon BigSky, for instance, offers numerous reverb algorithms and can store hundreds of presets, each with custom settings. The trade-off is complexity: more knobs to learn, deeper menus to navigate, and firmware that needs occasional updates.

What to Check Before You Buy A Reverb Pedal

Power is the first practical question. How much current does your reverb pedal draw? Some reverb pedal designs are efficient enough to run on a simple 9V battery or a modest power supply. Others, especially stereo reverb pedal units, can draw 300mA or more. If you're already running a full pedalboard, adding a power-hungry reverb pedal means upgrading your power supply—an easy thing to overlook until you're at a gig and you have a clicking noise that didn't exist in the rehearsal room.

Check the polarity: most reverb pedals use center-negative 9V, but some use centre-positive. Connecting the wrong polarity will damage your reverb pedal. If the reverb pedal uses 18V or 24V, make sure your power supply can deliver it.

Look at the footprint. Does your reverb pedal fit your board? Does it interfere with nearby pedals? A large reverb pedal board unit might have side-mounted jacks that stick out. A compact reverb pedal saves space but might have controls so small they're hard to adjust live.

Check the bypass type: true bypass means the reverb pedal is completely removed from the signal chain when off, preserving your tone. Buffered bypass is fine for most setups but can interact unpredictably if you're chaining long cable runs. Some reverb pedals offer "trails," allowing the reverb to continue after you bypass the reverb pedal—useful for live transitions, not useful if you want silence.

If you're using stereo, confirm the reverb pedal handles your I/O setup. Stereo operation on a mono guitar rig is redundant unless you're recording or using multiple amps.

MIDI, Presets and Expression Control

Modern reverb pedals often include MIDI control, letting you change settings and recall presets from a MIDI controller or even a keyboard. This is powerful for anyone playing longer sets or multiple songs with different reverb characters. Expression control—typically an expression pedal input—lets you sweep parameters like decay or mix in real time, adding dynamics to your reverb pedal sound.

Preset storage is useful if you need more than one reverb sound. A simple reverb pedal with three knobs and no presets forces you to dial in your sound fresh every time. A reverb pedal with 50 preset slots lets you store a different setup for each song, instant recall. However, preset functionality also means more menus and possibly a small screen—something to live with on stage.

Sound Quality and Algorithm Design of a Reverb Pedal

This is harder to judge from a spec sheet. Some reverb pedals use algorithmic processing—mathematical models that simulate reflective spaces. Others use convolution, which captures the acoustic fingerprint of a real space (or device, like a classic spring tank) and applies it to your signal. Convolution reverb pedals often sound more realistic because they're using actual recordings of real spaces. Algorithmic reverb pedals are more flexible and can offer sounds that don't exist in the real world.

The only real way to know if a reverb pedal sounds good is to hear it. Many manufacturers offer demo videos or audio clips. If you can, try it in person at a guitar shop, playing through your own guitar if possible. A reverb pedal that sounds lush through a shop amp might sound thin through your amp, or vice versa.

Budget Considerations

Budget reverb pedals (under £100/$120) are often surprisingly good. The Boss RV-1, for example, is compact and affordable. Mid-range reverb pedals (£100-300) offer better sound quality, more algorithms or presets, and often include features like expression control. Premium reverb pedals (£300+) are where you find boutique sound design, deep customization, stereo operation, and the kind of build quality that survives years of touring.

For most players, a mid-range reverb pedal is the right balance. You get good sound and useful features without the premium price. If you're just starting out, consider a budget option first—learn how to use a reverb pedal, figure out what you actually want, then upgrade if needed.
