DISCLAIMER: This is all guesswork and I assume no responsibility if you wreck your guitar.

Let's think ... four 1.5 Volt cells will probably provide almost 6.5 Volts when new so I'd assume the guitar requires 5 Volts for the electronics. You could check that by running it on three brand new batteries, that should give you nearly 5V.

PSU's providing regulated 5 Volts are widely available, all you'd need to do is connect it (the right way round!) to the battery compartment and add some kind of socket somewhere on the guitar body to plug it in. I'd make sure it's a well-regulated supply as PSU noise could be a problem. Most cheap PSU's aren't properly regulated, they're just rectified and filtered but a 5 Volt regulator is very easy to construct. The only unknown would be the current draw which I'd imagine would be fairly substantial to drain batteries so rapidly. Maybe a couple of 9 Volt batteries in parallel with a 5 Volt regulator and a heatsink would work?

As everyone's been saying, the Roland people did a bad job on the VG electronics. They knew the power requirement, they've got considerable experience with designing battery powered musical equipment, why did they build such a turkey?


Sorry. Very poor design requiring mods to the guitar body and two cables running to the guitar. Read my two posts describing how to do this with one cable and no body mods.


I was thinking out loud rather than offering any kind of ready made solution. I wouldn't claim to be able to solve all the PSU problems without having looked closely at a VG strat.

Did the PSU need a voltage regulator? I've always found the cheap ones introduce a lot of hum.

The question really should be..why didn't they provide what we're talking about in the second generation guitar. My guess is that they were trying to one-up the Line 6 guitar which is also none but a battery powered rig. Anyone have any knowledge of similar issues with that make?


Speculate all you like. I'll go out and build a cable and power supply for the OP and sell it to him. Cost will be $200.00. :lol: :lol: :lol:




Well, I won't really, but it's not rocket science.

To answer ZZDocs question, probably the same reason many things aren't done to provide something we would like to see: minimal return on investment.

For the record, Line 6 uses a lithium ion battery (probably like a laptop battery) with 12 hours of life.

Not sure this would work, and I take no responsibility for it damaging your axe, but the USB port on a laptop computer puts out 5V DC (not sure of the amperage, but I'm sure that that information is available) perhaps simply plugging a USB cable into a laptop or a universal USB phone charger at the "pedalboard end" and creating an adapter at the guitar end would work. From other posters, it seems that the voltage needed is between 4.8 and 6V DC.

just a suggestion, take it for what it's worth.

Sorry. Didn't mean to jump on you like that. :oops:

Very few wall wart power supplies used with pedals are regulated to my knowledge. Batteries certainly aren't. There may be some sort of regulator built into the guitar.

The OP seems to have vanished. I guess if he can't buy what he wants ready made, he is not interested in hearing about what could be done to solve his problem. Hope he has a LOT of batteries. :roll:

Easy now. Don't take it personally. Your expertise and creativity are appreciated. He might just not be interested in mucking around with the innards of that piece. I've got one. I'm conscious of the instructions relative to troubleshooting and repairs. I certainly would not want to be doing something irreversible to it.
The same attention to details applicable to any battery supported gear has to be undertaken with this piece. It's really a no brainer.

I don't but it really is not that hard of a problem to solve.

Yes the new Roland G-5 POWER SUPPLY will work on your Fender VG Strat contact Roland they have them . It is call CN-1 power pack you will also have to have a Boss PSA power adaptor 9 Volts it is sold seperate . They just started selling them I got mine today .

That's an about-time accessory. Always hated having to pull the box inbetween usages or long down periods when batteries can leak. I take the battery out of my Claptons for that reason. However....the Roland website gives little in the way of visual information. How long a cable can be provided for the connection??

The CN-1 is Great the power cord is long it will work on stage . It does make the VG sound much better you are getting a full 9 volts . You can contact Roland they will sell you the CN-1 no more batteries . You will have to also to order off amozon or e-bay a BOSS PSA 9 volt power supply . I seen them on ebay for 6 bucks. The phone number for Roland in California is 323 890-3700. The CN-1 does away with the batteries you just place it in the back of the Fender VG it has a auto switch if you forget to turn the switch off on the back it has a auto on off after 9 hours it will turn the power off . You will need to strap the Boss PSA wire to your Guitar cable going to you amp or foot pedal board. It is great works perfect Axe sounds great BECAUSE YOU ARE GETTING FULL 9 VOLTS OF POWER . :mrgreen: :lol: :lol: :lol: :lol: :lol: :lol:

Hi, just on this power problem now, the CN-1 is not on sale any more...
So was thinking on making one? wonder if the terminals that the box has is delivering 9V? or maybe it has a regulator inside for 6V?
Can someone who has the CN-1 and a multimeter check for me please?
Thanks.

Regret not having grabbed one the minute I learned about them. Put too much faith in Roland's reworking of that guitar and it remaining available for any decent ;enght of time.
