Sushi Box FX More v2

The Sushi Box FX More v2 is a fully tube-driven harmonic enhancer in pedal form, designed to bring out the best in an existing rig rather than change its core character. The maker describes it as delivering "the warmth, punch, depth, and touch sensitivity of a real tube preamp stage," with clean tones becoming deeper and more dimensional and driven tones feeling tighter and more focused¹. It builds on the original MORE concept with a refined circuit, developed in collaboration with guitarist Doug Weiand¹.

Delicious Audio frames it as "a high-end studio tool designed to take a great rig and simply make it more alive," not something meant to fix a flawed signal chain². It operates as an always-on enhancement tool, and Bass Musician Magazine's review of the original More noted that many players use it that way, adding subtle tube flavor to an otherwise solid-state rig or pedal chain³.

A tube-driven harmonic enhancer

The More v2 sits in the preamp pedal family, but its job is enhancement rather than tone shaping. Delicious Audio describes what it does as adding "natural upper-harmonic richness, sustain, and clarity, making clean tones more dimensional and driven sounds tighter and more focused"². The maker's own description is similar: harmonic richness, sustain, clarity and a tactile response that makes every note feel more alive and more connected¹.

The tubes inside are a carefully selected NOS 12AV7 paired with a 12AT7¹. The maker states the tubes run in genuine thermionic emission, meaning real tube operation rather than a solid-state circuit voiced to sound tube-like, at around 340V internally¹. That internal high voltage is what separates it from low-voltage tube pedals that run their filaments but starve the plates.

The main control added in v2 is a bass cut switch. The maker says it "allows you to control low-end bloom and tighten up high-gain or extended-range instruments" without sacrificing body¹. Delicious Audio puts it the same way: it tames low-end bloom and tightens extended-range or high-gain setups without stripping away essential body². For bass players and anyone using extended-range guitars or modern high-gain amps, that switch is the practical difference between the v2 and the original.

Power: at least 600mA

This is the part a buyer needs to get right. As a tube pedal, the More v2 requires a high amount of current to operate correctly. The maker recommends a 9 to 12V DC power supply capable of delivering at least 600mA¹, and Delicious Audio's coverage repeats the same requirement². RockBoard's PedalPedia entry for the More lists 9V DC center negative and 600mA as well⁴.

The pedal is sold in two versions: $250.00 for the pedal alone and $263.00 with the power supply included, as listed in October 2026¹.

The original MORE and this version

The More v2 builds on the original MORE concept with a refined circuit¹. Bass Musician Magazine reviewed the original in November 2023, calling it "the spartan, aptly named 'More'" and describing it as "designed as a tone enhancer to bring more sweetness, complexity, and punch to your sound"³. That review noted the original contained two tubes, a 12AU7 and a 12AT7³, so the v2's NOS 12AV7 replaces the 12AU7 of the first version.

The v2 also adds the bass cut switch described above, which the original did not have. Both versions share the same basic idea: an always-on tube stage that enriches what is already there. RockBoard's PedalPedia classifies the More as a booster⁴, which reflects how many players use it, though the maker positions the v2 specifically as a harmonic enhancer¹.
