The Funny Little Boxes 1991 is a dual-drive overdrive pedal handmade in the UK, first released in 2021. Its whole reason for existing is Pearl Jam's debut album Ten: the builder's stated aim was "to capture the sound of the Ten album by Pearl Jam and the blueprint for the sound is a mid-forward drive pedal being pushed into a cranked, high-gain amplifier"1. Rather than one clipping stage doing all the work, it runs two cascading gain stages, so you can set a light edge on the first and let it drive the second into heavier saturation.

Guitar World describes the circuit as two gain stages, the first in the ballpark of a Tube Screamer driving a second, Marshally gain stage, on the basis that Stone Gossard and Mike McCready pushed their JCMs with overdrive pedals on Pearl Jam's debut2. The pedal is handmade in the UK by Andy Ilgunas and sold for £99, approximately $13023.

The controls

The control layout is straightforward: six knobs, no switches, no menus. Gearnews noted when the pedal launched that it has two gain knobs for its two gain stages, where the first one drives the second, plus a three-band EQ section and a standard master volume control5.

ControlWhat it does
Gain 1First gain stage; offers a Tube-Screamer-style edge4
Gain 2Second gain stage; brings JCM800-like saturation and punch4
Bass, Middle, TrebleThree-band EQ section5
VolumeMaster volume control5

The two gain knobs are the heart of the pedal. Because the first stage feeds the second, you can dial in anything from a gritty boost to full-blown lead tones4: a low Gain 1 setting into a higher Gain 2 keeps the Tube Screamer-style midrange edge in front of the heavier stage, while running both high stacks the two stages for the saturated, punchy character the maker compares to a JCM8004. Gearnews' Jef summed up the layout at launch: "Overall, I quite like the simple control layout, and the demo video below sounds pretty good as well."5

History and versions

The 1991 was Funny Little Boxes' first original pedal design, launched in 2021 and priced at £99, with the first two batches already sold out at announcement15. It grew out of a challenge from the YouTube channel Let's Play All1: Matt Webster, a Pearl Jam tribute band guitarist who runs the channel, challenged the builder to recreate the Ten tones, and Gossard and McCready's Ten-era sounds became the design inspiration2. The circuit itself was a collaboration between Andy Ilgunas, Marc Dunn of SoundLad Liverpool, and Simon Andrews of JSA Effects3.

The original run used a distinctive pink enclosure. In June 2024 that changed: the supplier ran out of that particular shade of pink and could not source any more, so the builder moved to limited edition colorways, starting with a Gold Sparkle finish6. The Gold Sparkle is the first in a line of new finish runs6.

The Gold Sparkle 1991 is a cosmetic difference only. The builder confirmed at the time: "I can assure you it is a cosmetic difference only. The circuit is still exactly the same in every way and completely uncompromised."6

There is also a DIY route. GuitarPCB publishes a build document for a bonus PCB based on the Funny Little Boxes 1991, described as a unique dual-drive overdrive inspired by the tones of Pearl Jam's Ten era, combining two independent gain stages with a 3-band EQ4. That PCB is only available as a free bonus with qualifying orders and is not sold on its own4.

What reviewers said

MusicRadar's review team found the pedal stands on its own merits rather than trading on nostalgia. Their overall verdict3:

"Beyond any grunge nostalgia, this is an excellent drive pedal from a UK builder and its mid-focussed character provides a huge appeal for us."3

MusicRadar review team3

The mid-focused character is a direct consequence of the design: the first gain stage sits in Tube Screamer territory2, which pushes the second stage the same way Gossard and McCready's overdrive pedals pushed their Marshall JCMs on Ten2. Guitar World notes the album's distorted tones are thought to have been made using a combination of Marshall JCMs, Ibanez SD9 or TS9 pedals and a SansAmp Distortion1, so players chasing that sound with separate pieces can compare the 1991's two-in-one approach against a Boss SD-1 vs Ibanez TS9 style pairing.

Questions

What pedals did Pearl Jam use on Ten?

The distorted tones on Ten are thought to have come from a combination of Marshall JCM amplifiers, Ibanez SD9 or TS9 overdrive pedals, and a SansAmp Distortion, with Stone Gossard and Mike McCready pushing their Marshalls with overdrive pedals. The 1991 pedal puts that two-stage recipe, a mid-forward drive into a cranked high-gain amp, in one box.

Who designed the Funny Little Boxes 1991?

The 1991 was a collaboration between Andy Ilgunas, Marc Dunn of SoundLad Liverpool, and Simon Andrews of JSA Effects on the circuit design. It began with a challenge from Matt Webster, a Pearl Jam tribute band guitarist who runs the Let's Play All YouTube channel, to capture the sound of Ten.

Is the Funny Little Boxes 1991 true bypass?

Yes. MusicRadar's review lists the 1991 as true bypass, so with the pedal switched off your signal passes through without buffering. It runs on 9V DC only at 11mA, so plan on a power supply rather than a battery.

Is there a DIY PCB for the Funny Little Boxes 1991?

Yes. GuitarPCB publishes a build document for a bonus PCB based on the Funny Little Boxes 1991, a dual-drive overdrive with two independent gain stages and a three-band EQ. The PCB is not sold on its own; it comes as a free bonus with qualifying orders.

Does the Gold Sparkle 1991 sound different from the pink one?

No. When the original pink enclosure color was discontinued by the supplier, Funny Little Boxes moved to limited edition colorways starting with Gold Sparkle. The builder confirmed it is a cosmetic difference only and the circuit is exactly the same in every way.
