How we ranked these overdrive 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.
- True bypass weight 2
- Runs on batteries weight 1
- Stereo in/out weight 1
Buying advice: overdrive pedal for blues
Start with true bypass and the knobs
True bypass is a feature each pedal here shares: the signal stays untouched when the effect is off. Knobs differ across these pedals: the IOppWin has Volume, Tone and Drive, the Shaevle has Volume, Tone and Gain, and the Aestivate has Drive, Tone and Level. Match the knobs to the controls you reach for while you play.
Check weight and size for your board
Weights here run from 0.3 lb to 0.7 lb: the Aestivate weighs 0.3 lb, the IOppWin 0.4 lb, the Caline 0.6 lb and the Shaevle 0.7 lb. The AFOT measures 3.7 x 1.5 x 1.5 inches, the IOppWin 1.9 x 1.25 x 3.6 inches and the Aestivate 3.0 x 1.0 x 1.0 inches. Match the weight and the measurements to the space on your board.
Plan for the power adapter
The power adapter is not included with the AFOT, IOppWin, Caline or Shaevle pedals, so plan to buy an adapter if you do not own a 9V adapter already. The IOppWin runs on DC 9V at 6mA, the Caline uses a 9V center negative adapter and the Shaevle works with DC 9V 500mA adapters. Check the voltage and current figures against the adapter you own before you buy.
