JHS Pedals 3 Series Hall Reverb

The JHS Pedals 3 Series Hall Reverb is a compact reverb pedal from JHS Pedals' budget-minded 3 Series, released in November 2021 alongside the 3 Series Phaser and Flanger¹. Where the original 3 Series Reverb covers everything from small rooms to long ambient washes, the Hall Reverb is aimed squarely at the big end of that range: JHS says it is "inspired by the sounds of large reverberated spaces, cathedrals and halls," spaces favored for their naturally long decay times²¹.

For a player, that means a pedal built for depth and size rather than subtle room glue. MusicRadar's Jonathan Horsley described it as offering "huge ambience space for your electric guitar tone to sink into"³, and Delicious Audio called it a fit for "players who are searching for massive, infinite and even otherworldly reverb"⁴.

What the Hall Reverb does

The pedal sits in the middle of JHS's two-reverb offering at the budget level. The original 3 Series Reverb is described by Delicious Audio as "an extremely versatile unit that allows you to create the perfect amount of space for your guitar, from small room sounds to nearly endless washes of ambiance"⁵. The Hall Reverb narrows the focus to one flavor: the long, cavernous decay of a large hall or cathedral, the kind of space players reach for when they want a note to bloom and hang in the air²¹.

Guitar World's news coverage of the November 2021 launch noted that the Hall Reverb "aims to emulate the sounds of large reverberated spaces, think cathedrals and halls, which" are favored for their naturally long decay times¹. It arrived as one of three new $99 pedals that branched the 3 Series into modulation and expanded its reverb options, bringing the range to ten units at that point¹.

The controls: three knobs and a modulation toggle

Like every 3 Series pedal, the Hall Reverb keeps the control set minimal: three knobs and one toggle, a layout JHS says is "perfect for beginners and" experienced players alike².

The toggle is the pedal's one twist. Delicious Audio's coverage of the launch highlighted that the switch works by "adding modulation to the Hall Reverb," giving the decay a moving, chorus-like character rather than a static wash⁶. With only four controls total, there is no menu diving, no presets and no screen: everything on the pedal is on the surface.

Power comes from a 9V DC supply with a negative center plug, drawing 70mA, the same spec as the Phaser and Flanger released with it²³.

How it differs from the 3 Series Octave Reverb

The Hall Reverb's closest sibling in the lineup is the 3 Series Octave Reverb. Both are $99, three-knob reverb pedals with a single toggle, but the toggles do very different things⁷².

The Hall Reverb's toggle adds modulation to a conventional hall decay⁶. The Octave Reverb instead layers octave-shifted pitch into the reverb's tail: "Toggle up layers in upper octave sounds, while toggle down layers in lower octave sounds," in JHS's own description⁷. Delicious Audio described the Octave Reverb as an effect that "mixed ambient reverb and octave effects in the reverb's decay," and Pedal of the Day framed it as JHS's take on Brian Eno's shimmer effect⁷.

In short: choose the Hall Reverb for a big, natural-sounding space with optional movement, and the Octave Reverb for a synth-like, pitch-shifting wash. A player who wants both size and pitch shifting in one box may also want to look at JHS's newer PHERB.

Where it is made and what it costs

Every 3 Series pedal is made by JHS in Kansas City, Missouri, with the maker citing its own parts sourcing, quality control and attention to detail⁸⁹¹⁰. Guitar World's budget reverb buying guide called out this point directly:

The list price is $99.00 USD, the figure JHS still publishes and the price shared across the 3 Series lineup². At launch in November 2021, MusicRadar reported it as "available now, priced £/$99," with the UK price at £99³. Delicious Audio also noted a Sweetwater sale price of $84.15 in December 2021, so street prices can dip below list³⁶.

What reviewers said

Published coverage of the Hall Reverb has been positive and consistent about its intent. Guitar World reported it as suitable for "massive, infinite and even otherworldly reverb"¹, and MusicRadar's launch coverage emphasized the sheer size of the effect, calling it "huge ambience space for your electric guitar tone to sink into"³.

The broader 3 Series reverb line has drawn praise on value grounds. In Tone Island's 2026 reverb pedal comparison, Adam Connell named the JHS 3 Series Reverb his budget pick, calling it "a sensibly priced reverb pedal that punches well above its price point"⁷¹². Pedal of the Day, reviewing the Octave Reverb, summed up the lineup's appeal: "with the entire 3 Series lineup priced at only $99.00, it's a pretty hard deal to beat!"⁷¹³
