| I've tried to use both the Boss RV3 and a Boss Chorus pedal with a 9 volt battery (both were new batteries) yet neither worked with the device. Both work fine using the power supply adapter. Anyone else had this trouble, and if so, is there a fix? Thanks steve t |

If it were just one pedal I would suspect a dirty or bent power jack----the jack where the DC adapter plugs in has an extra leg that opens the battery circuit, diverting the power flow to the adapter. If this part of the jack failed to close the circuit when the plug is removed, the battery circuit will not function. This would either be a bent or a dirty part. However on two pedals? I don't know.
I can tell you, though, that running an RV on batteries is a futile endeavor. You won't get more than a couple of hours out of a fresh battery. Don't know about the chorus. |

| Just a thought. Most stomp boxes when using the battery mode need to have a cord plugged into the input jack before the LED lights up. When using the power supply, the LED will light up as soon as power is supplied to the unit. |

I agree with John...a bad DC input jack. The internal switching blade can be bent by using a wrong-sized DC plug. I used to see that frequently in Boss pedals, and others. So, I wouldn't be surprised to see more than one with that problem.
The RV-3 does eat batteries very fast. The PSA adapter should be used on that one.
By the way, those PSA adapters are regulated power supplies, which means they maintain a clean 9v. output...unlike generic adapters.

Just for reference, I use a Digitech Distortion Factoy pedal that I can put a new battery in at the beginning of the (4 hour) gig, and by the end of the gig, the battery is dead. So, I just use power supplies for my effect pedals.

Here is a shot of a typical Boss Pedal. You can see that the AC adapter jack has a contact that must close when the ac adapter is removed to allow the battery negative to connect. Battery tip is negative and battery plus is at ground potential via the 1/4" Tip/Ring/Sleeve (stereo) input jack. The ac adapter has a blocking diode and 100 ohm resistor in series with its shield and then goes to ground. This prevent an improper supply from doing damage. The battery itself goes to ground via a short between tip and ring on the input jack, when a Tip/Sleeve (mono) 1/4" guitar cord is plugged in. That is basically the battery on/off switch.
