The Sanyo Pedal Juice is a power supply pedal that runs from a 9v rechargeable Lithium-Ion battery contained within the pedal. You'll then be able to run a huge chain of 9v pedals directly from the pedal for seemingly limitless hours.

This one is definitely worth a look as a tool for convenience, an investment and even an upgrade for a mains supply unit.

Now it's no secret that I love pedals, I spent a good few years on The Gear Page spending every bit of my earnings (and a huge chunk of my student loan) on whatever good quality pedals I could read about. I can do everything from make my guitar sound like an organ, to a square wave 80s synth sound for some serious electronic vibes. The problem is always power; any purist will tell you that batteries are the only way to go, but the spiraling cost of duracell 9v cells and the added frustration of having to mess around with screw drivers lead me to pick up a Trex Fuel Tank - until now.

The gear snobs are so set on batteries because a mains fed power supply is ultimately dealing with huge currents which it's managing and distributing to your effects chain. An inevitable byproduct of this is that you will usually pick up some sort of hum - and this will vary depending on where you've got it plugged in. In an isolated plug in a studio the hum would be minimal, but if you were plugged into an extension cable that's also feeding a computer, two moniters, speakers, an amp etc - you're going to have some real buzz. With the pedal juice, this will never happen and no matter where you are you're guaranteed to get the exact same high quality power supply for all of your musical needs.

That word "musical" is key - this pedal isn't only limited to guitar players and our stomp boxes. This power supply will run anything at 9v. You could use it for a loop station, a keyboard, a drum machine, or even a travel amp like the Roland CUBE street. So this pedal could help you out in a situation where plugging in to a wall isn't even an option; perfect for those impromptu busking sessions. You can even run a small multitrack recorder from this pedal so the applications are limitless.

Of course, everyone reading this will probably be using this as a tool for their guitars and effects, so lets take a little bit more of a look into how the pedal works and how It can benefit you.

The pedal is a standard box size (65 x 42 x 120mm) weighing less than 300g. It has only 3 connectors on the back - two 9v DC outputs capable of supplying anything up to 2000mA of power (more on that later). There's also another input for the unit's charger (supplied). The only other user interface is the big power button on the top of the unit. Press it and the unit turns on, but the real nice touch is that pressing it again won't turn it off, you won't accidently turn this off. You need to press the button and hold it for a few seconds.

It's also worth noting that the unit has achieved a JIS IPX3 water resistant compliance level rating - so there's no fear that this will get a bit of rain or beer spilt on it and suddenly you'll loose your power. This pedal has been designed to withstand all of the hazards the gigging musician might face.

So let's talk figures, what is this unit capable of?

Well, as I mentioned previously this pedal can supply up to 2000mA of power, now that is an excessive amount of power - your average analog effect pedal (like the JTK Alchemy pictured above) will draw about 10mA of juice. So in theory I could have a chain of over 100 stomp boxes and this unit isn't going to break a sweat.

When we translate this information into the real world you can probably deduce that the more you're drawing from the Sanyo Pedal Juice the shorter the battery life. Though short is a relative term.

We could run a single stomp box for around 50 hours of continuous play, and a small chain of 3-4 pedals (your average gigging/clinic setup) would have plenty of energy 25 - 30 hours. So unless you're playing a freakishly long gig - you'll drop dead of exhaustion before your pedals do. The incredible thing about this pedal is that it will not struggle to run an entire board, in fact to test it I ran my Hellcat Molly rig overnight and when I woke up we still had power. If a standard 9v battery has a load of 500mA it will last for under 30 mins - The Sanyo will give you over 4 and a half HOURS.

The LED on the top of the pedal is an incredibly useful guide as to how your battery is doing and when you should recharge it. It will light up in either green, amber or red - this is a direct indication of how much battery life you have. When the Pedal Juice is glowing green you have over 60% power left, if it drops to amber you're between 30% and 60% of your power, the red means you're under 30% - but that still doesn't mean you should panic as you have plenty of time to finish your gig - In fact if you were running a full board on a gig and you hit red in the first song you'll make it to the end of the gig no worries.

With a list price of $199 this unit certainly isn't cheap (about $130 street price) but you really need to do the math to see why this works out as a great deal. For starters a high quality mains power supply will cost you anywhere from $200 (The T Rex Chameleon) so you're already looking at a saving if you're in the market for a power supply. Of course, thats without taking into account the benefits of having a battery power unit like this.

The tougher sell is for those using batteries - currently on Musician's Friend Duracell 9v batteries will set you back $10.99 for a packet of two. My current gigging board requires 7 batteries, plus there are at least 5 other pedals that are in constant circulation, making appearances on pop gigs, country gigs and even just one or two in my gig bag for my students at The Academy. That's 12 batteries already ($65) and these wont last me more than a couple of months - so in the short term it's a big expenditure - but in the long run I'm saving a small fortune. I've been using this pedal for close to a year now so it's already paid itself off against batteries I would need for the smaller board.

That's all I need - It makes financial sense, It will last me for years and it makes going out and doing shows so much easier as I dont have to take a huge board with me If i'm only going to need a little compression and delay. The Pedal Juice represents great value for money and extreme portability - It's certainly worth your time.
