How we ranked these guitar pedals

Every pick ranks in Amazon's best-seller list for its category and has 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: small guitar pedal

Match the effect type to your needs

Effect type decides what the pedal does. The Donner shifts pitch with 7 shift types and 3 tone modes. The EX and the IOppWin shape tone with EQ bands, 7 on the EX and 5 on the IOppWin. The HOLY WAR adds distortion with 3 modes, and the reverb pedal adds space with 9 modes. Pick the effect type first, then compare controls within that type.

Check size, weight and power

The Donner and the reverb pedal carry Mini in their names, the EX and the HOLY WAR carry compact designs, and the IOppWin EQ is called tiny. Weights run from 0.4 lb on the EX, the HOLY WAR and the reverb pedal to 0.6 lb on the Donner, with the IOppWin EQ at 0.5 lb. For power, the Donner, the EX and the HOLY WAR run on 9V DC adapters, and the reverb pedal also accepts USB-C power.

Check bypass and knobs

True bypass appears on all five pedals, which means the pedal passes the signal untouched when off. Knob layouts differ: the Donner gives WET and DRY knobs, the EX gives a LEVEL knob, the IOppWin gives a master level control, and the reverb pedal gives Dry, Wet, Time and Level knobs. The HOLY WAR switches modes with a toggle instead. Compare knobs against the controls you adjust most.

Frequently asked questions

What does true bypass mean?

True bypass means the pedal passes the signal untouched when off. All five pedals here give true bypass, so the guitar tone stays intact with the effect off.

Do these pedals include a power adapter?

No. The Donner, the EX and the HOLY WAR each need a 9V adapter bought separately, and the reverb pedal takes a 9V adapter sold separately or USB-C power.
