I can't see any reason to do that unless the battery gets old. When you plug in the adapter, it automatically switches off the battery.

Hi, i need to know the exact power plug so i dont have to run the pedal on battery power.i know i need a 9v power supply but i dont know the size of the jack that goes into pedal..many thanxs..


Unfortunately, battery jacks and plugs similar to the type you're describing do not have any real standardization - unlike the outlets and plugs in homes and businesses have.

You best bet is to either bring the plug / jack to a shop to match it or contact the instrument's manufacturer to obtain the connector specs for physical dimensions

Be sure to obtain the power requirements in either watts or amps so that you can obtain a power source capable of delivering what you need without overheating during longer periods of use. Adding 25% to 50% more amps or watts to the minimum required should provide years of trouble free service. Example: 9VDC at 50 watts should be supplied by a 9VDC 62 watts or even 75 watts; or in the case of a rating of 9VDC at 6 amps should be supplied by a 9VDC at 7.5 amps or even 9 amps. With DC powered devices, make sure you observe proper polarity! Good luck!

My boss metal zone pedal power light wont come on when i hook the ac adapter to it i get nothing but a hum and no output clean or distortion,then when i plug a 9volt battery in it gives only clean tone...


There is a switch contact that connects the battery when you unplug the AC adapter. These commonly get sprung and cease to make contact leaving the battery disconnected when adapter is unplugged, resulting in no power. Verify the battery is being connected and see if the unit works properly. If so the adapter is either the wrong one or defective.
In other words, there may be two problems.

The zoom g1x is dead. no power. tried adapter from my other zoom pedal but nothing. opened it up and everything seems in tact. was working fine saturday, dead sunday. only one month old.


The first thing i would check is the ac adapter .Make sure you are getting the correct voltage from the adapter.If you know how to use a voltmeter or know someone that has a volt meter,check it with it unplugged from the guitar pedal,most of these have a voltage range from 9 to 12 volts dc.you could also take it to your local radio shack or local repair shop and they will be glad to check it for you for free.after you confirm the adapter and it is ok then the next thing you will check is the input jack assy on the pedal,input jack assy are soldered onto the board at the factory,these jacks ,no matter what it is are famous for cracked solder joints where the pins of the jack go into the board because of stress delivered to it during plug ins and plug outs.if you dont know how to use a sldering gun or dont want to you will have to take it it to your local repair shop-cost should be around 15.00, 20.00 tops,make sure that your guitar cables are good,check the 9volt battery inside the unit if it takes one,if its dead that could be your problem,if all above fails i would send it back to the factory or wherever you bought it.,good luck been playing for about 30 years myself,rock on

How do I open the unit to replace the 9volt battery?


Many of these units the pedal actually tips up on its hinge exposing the battery compartment.

Guitar pedal power problems


Wow! All these are supposed to have a standard polarity connection.

Verify that this pedal has the opposite polarity of the power.

Frankly, having a second supply is expedient solution... The only other way is with blocking transformers or capacitive coupling...

I have never heard of a pedal having opposite polarity. PLEASE fill us in on this problem for future reference.

BOSS DD3 STAYS ON AND WILL NOT TURN OFF


It's supposed to do that. An extra lug on the input jack is connected to the battery and/or power supply's ground.

So the only way to power off any pedal is to disconnect the input jack. If you use a power supply and power multiple pedals you can simply disconnect the power supply to cut power and avoid unplugging each one.

How to set up with amp and distortion pedal


With everything switched off. I will surmise that you are using the onboard battery with the foot pedal and not a power supply.
1. Plug lead from guitar/instrument into INPUT side of pedal
2. Plug lead from OUTPUT side of pedal into amplifier INPUT.
3. Turn amplifier volume to about 10 o'clock - to stop blowing your ears out.
4. Turn volume up on guitar to acceptable level.
5. press foot switch on pedal and adjust pedal controls to suit your type of distortion.
6. Play like Hendrix.
Good Luck
ps Just as an after thought rechargeable 9volt batteries are the way to go. I've been using them for years as I always get caught up in the power cable.
If you're going to add another pedal like a Phaser, Compressor, Flanger or what just use small connect leads between each pedal but always, always put the compressor pedal last in the line.
