Sound — 10
The most important thing to look at when evaluating a new power supply is whether it is truly CLEAN power, or whether it adds any noise or other artifacts to the signal. Running solely off of a Pedal Juice, powering a Suhr Riot distortion pedal, no additional noise was added in comparison to the pedal being plugged directly into the AC outlet.
Overall Impression — 8
It seems the best use for the Pedal Juice would be for a guitar or bass player using a dedicated multi-FX board as their amp simulator as well, direct-in to a P.A., and allow them the cleanest and quickest setup possible, with the fewest number of cords and connections to deal with at a gig. While every gig I have played has had a power strip and an extension cord available to me, this device could also be very handy for people playing outdoor gigs, or who want to play in an odd part of their house or rehearsal space where an outlet may not be handy. However, most guitarists or bassist still plug into a traditional amp, which still requires a power outlet in most cases, so the situations where this is truly necessary are somewhat limited. While the situations where this may come in handy are a bit limited, the Pedal Juice does come included with everything needed to get up and running, and further it provides enough power to handle some medium-sized pedal boards. This is a novel, new category in the musical instruments category, and there is undoubtedly an audience for the Pedal Juice.
Reliability & Durability — 7
The plastic housing on the main battery unit seems to be the same toughness and quality as, say, a television remote control. It's not terribly heavy, and that's worrisome, as a box like this, mounted to a pedal board, will get jumped on and stepped on in the madness of a rock show. The cables themselves all seem typical, and everything worked as advertised. A fully loaded (2000 mA) power drain will only last an hour, which makes this difficult to use for a larger pedalboard setup, but this can last 15-20 hours between charges for a multi-FX board (I.e. Boss GT-10), which seems like a perfect mate to the Pedal Juice. The charge times were 3-4 hours on an empty battery, as expected.
Ease of Use — 10
The Pedal Juice pedal, from Sanyo, is a rechargeable power source for 2 standard Boss/Ibanez 9v guitar or bass effects pedals, and can also power some multi-FX units as well, depending on power draw. The Pedal Juice is branded as part of Sanyo's Eneloop rechargeable lithium-ion battery technology line, and carries the same clean, modern look to the components with a white finish and rounded edges in a hard plastic case (not unlike many Apple iPod/Mac/etc products). The idea is simple; use the included AC adaptor (not a wall wart!) to charge the battery box, and then you can power a small pedal board of two pedals or a multi-FX unit plus another pedal, for up to 50 hours without needing to plug into a wall for power. The main battery unit is a little smaller than a typical Boss-style pedal, and can be mounted to a pedal board to keep it in place. The included charger plugs into the top, and will fully recharge in 3-4 hours. Two 9V DC cables are included, that run from the output jacks to the effects units. A polarity conversion cable is also included. The Pedal Juice can handle up to a 2A (2000 mA) power draw, which is enough to run a Boss GT series power board, as an example, and more than enough to handle two typical 100 mA pedals. Further, if paired with a 1-Spot or similar type of power splitting cables, several pedals could be handled simultaneously.
