How we ranked these multi-effects pedals
Every pick has at least 100 customer ratings on Amazon and a listing with real specifications. The order mixes two things: how each model compares on the specs below (higher share of the best value in this group scores more), and how widely it is bought. The spec score runs from 9.0 to 9.8 and only compares these picks with each other. A spec the listing does not state is left out and the other specs are re-weighted; a listing with fewer than 2 stated specs is scored at half. We do not test gear in person. Full method.

Buying advice: bass multi effects processor
Count effects and amp models first
Effect counts and amp models decide how many sounds one pedal covers. The SONICAKE QME-20 runs over 130 effects, the Matribox runs 130 effects with 40 amp models, and the BOSS GX-10 runs 170 effects with 32 amp types. The LEKATO pedal runs 9 amp models with 8 IR cabinets, and the Zoom B1X Four runs over 70 bass effects with 9 amp models. Compare the counts first, then check the looper and the preset slots.
Check the looper and preset slots
A looper records a phrase and plays it back while you add parts, and preset slots store your chains. The QME-20 adds a 20-second looper with 100 preset slots, and the Matribox adds a 90-second looper with 198 presets. The LEKATO pedal holds 3 preset modes. If looping matters to you, compare the looper length first.
Check power and recording options
Power decides where you can play, and USB audio decides how you record. The QME-20 runs on a built-in battery for up to 3.5 hours and adds USB audio. The LEKATO pedal runs on a built-in battery for 6 to 8 hours and records to a PC or phone. The Matribox runs on corded electric power and adds USB audio with OTG. Pick the power source that fits your setup, then check the recording path.
