The Line 6 Helix HX Effects is a floor multi-effects pedal built around the Helix effect algorithms, without amp modeling. It carries a large library of effects, up to eight of which can run at the same time, in a unit weighing 1.5 kg1.
What it does
The HX Effects takes the effect side of the Helix platform and puts it in a pedalboard-format floor unit. GuitarPlayer's buying guide counts 104 effects1, while Guitar Pedal X's review puts the total at approximately 117 effects2; the two publications disagree on the exact count, so both figures are given here. Either way, the set spans the effect types a player builds a board from, and up to eight of them can run simultaneously2.
Because there is no amp modeling, the HX Effects is positioned for players who run a real amp or another modeler and want Helix effects around it, rather than players looking for a single-box rig. It sits in Line 6's Helix family alongside the full Helix Floor, the Helix LT and the smaller HX Stomp XL1.
Size and footprint
The HX Effects is a large pedal. Guitar Pedal X's reviewer Stefan Karlsson compared it directly against the Eventide H90 in an October 2024 head-to-head and found the difference stark2:
"Obviously the HX Effects is huge - being more than twice the size of the H90"
Its footprint measures 274 x 201 mm, which Guitar Pedal X calculates as 55,074 mm2 of board space2. That size is the trade-off for a floor unit with eight simultaneous effects and room for footswitches, but it is worth measuring against your board before committing.
Price
Guitar Pedal X's October 2024 review lists the HX Effects at $6492.

Questions
Does the Line 6 Helix HX Effects do amp modeling?
No. GuitarPlayer's buying guide lists it as a multi-effects unit with no amp modeling, focused on the Helix effect algorithms rather than amp and cabinet simulations. Players who want amp modeling in the same family would look at the larger Helix models instead, while the HX Effects is aimed at players who already have an amp or modeler they like and want Helix effects in front of or behind it.
How many effects does the HX Effects have?
The published figures differ. GuitarPlayer's 2026 buying guide counts 104 effects, while Guitar Pedal X's 2024 review puts the count at approximately 117. Both agree on the headline capability: up to eight effects running at the same time. The exact number depends on how the effect set is counted and on firmware, so treat both figures as close to one hundred.
