What to know before buying

Listing details to confirm

Listing details are inconsistent: the specifications give corded-electric power, 9 volts and 30 milliamps, while the feature listing says 9V battery or 9V DC adapter, 40mA and no 18V operation. Dimensions and weight also differ between the details and feature listing. Confirm the selected unit’s power requirements and physical measurements before purchase. The included-components field lists a power adapter, but the feature listing does not establish whether one is supplied.

Customer feedback reports positive impressions of the overdrive, sound, gain, reliability and build quality. That feedback may matter to players seeking a dedicated overdrive with adjustable Gain, Treble and Output, but it does not resolve the listing’s conflicting power and size specifications. The aggregate ratings are mostly five-star, with a smaller spread across lower categories, so experiences are not uniformly positive.
