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.
- Effects weight 2
- Looper weight 1

Buying advice: multi effects processor
Count the effects and amp models
Effect counts run from 60 to 250 here, and amp models run from 11 to 23 where the unit gives a count. The HX One has 250 effects, the GX-1 has over 140 effects and 23 amp types, and the Valeton has over 100 HD effects. The Zoom has 70 effects and 13 amp models, and the ME-90 has 60 effects and 11 amp models. A bigger count gives more choices, not better tone, so compare the effect types you actually use.
Check battery power before you buy
The Zoom runs on batteries, the Valeton has a rechargeable battery, and the ME-90 runs on batteries. The GX-1 runs on an AC adaptor, AA batteries or USB bus power. The HX One runs on a 9V power supply. If you play away from outlets, a battery-powered unit matters. If you always play near an outlet, ignore power and compare effects instead.
Look at memory and footswitches
Memory slots and footswitches decide how fast you change sounds while you play. The GX-1 has 99 preset and 99 user memories with three footswitches, and the ME-90 has 36 preset and 36 user patches with 8 footswitches. The HX One has 128 preset slots, and the Valeton has 100 patch slots with dual footswitches. Compare memory and footswitches against how many sounds you use.
