I have a old Boss Digital Delay sampler that sounds great but it will eat a battery in 2 hours. If i put it on a power supply ( boss wall wart) it does not sound near as good. I have tried ajusting my amp bass and trebble to no avail. any soulutions thkks

I bought it new in the mid 80's and it sounds best on a 9v battery (but drains it quick) . would a 1 spot sound better since its not a boss walwart. the manal says it uses a psa . There is a sticker next to the power supply jack that says PSA adapter 9V DC and the wall wart says PSA 1201 and does not sound as good as the battery |

May be a problem because it's digital, which generally have a larger current draw compared to analog pedals. Don't know whether your PSA adapter would supply enough power (although it should if it's a boss power supply). I have a 1 Spot which supplies 1000ma which is more than enough for the majority digital pedals I have (if not loaded up with multiple pedals that exceed what it's rated to provide).
Compare the rating of the PSA adapter to the rating of the pedal. Potentially could be the root of the problem.
If that's OK then it's possible the connections from the pedals power jack could be corroded, causing high resistance and reducing the current draw to the pedal. An '80s pedal is fairly old and natural degradation could be a problem. Not saying 100% it could be the cause but am trying to think out of the square.
Edit: As a side note I don't use any Boss power supplies with my Boss pedals (which I have analog and digital examples). I use either the 1 Spot, Strymon Zuma or a generic 1000ma filtered wall wart I picked up years ago. Never had any problems.

No surprise that it eats batteries. Digital delays and reverbs are very hungry. But am surprised that there is any difference in sound. If we were talking about an analog, maybe, but digital? *scratches head*

"If i put it on a power supply (boss wall wart) it does not sound near as good." Your power plug may be going bad...they run hot, and the filter cap(s) in them take a beating. The heat makes the caps expand; they leak electrolyte and go out of spec. When that happens, the PSU cannot supply stable current. You can test it for proper voltage with a DMM, but unless you have a clamp meter you cannot test it for the current it can supply under load. Try another PSU and see if that improves the sound. Me, I have one of these:  |

If we were talking about an analog, maybe, but digital? *scratches head* I'm thinking the same thing. The Boss PSA supplies 500ma which should be sufficient; I've never experienced a situation where it wasn't enough for a pedal, especially one from the 80's. But then Peegoo mentioned caps going bad. I've had some experiences with that, but only in an old Acer computer where the caps started bulging on the top. It was easy to identify the bad caps, just by looking at them. And after replacing them, the problems I was having disappeared. It might not hurt to take a look inside at the caps....? |

Bedroom player here, but I do have information.
I bought a fuzzbox from Target about 15 years ago. I haven't used it in some time, since I have since purchased a modeling amp that has an overdrive channel. But when I got it, I noticed it did eat batteries. I used an adapter with it, but I did find that when I used a power supply that I was using with my keyboard instrument, it worked much better. The keyboard's power supply was a 1-amp (IIRC) and the other power supply was I think 500ma.
Bear in mind, it was a "universal" power supply with multiple voltages and several plugs that could be used with either a positive or negative tip. It worked great. But I needed it for my keyboard instrument.

Nice rig Peegoo. I have been thinking of inserting a small multimeter into my rig. Being the geek that I am I thought I might like to see the actual numbers rather than lights.

I have a digidelay that will drain a battery in no time. Currently I use a One Spot to power it and my other pedals. It works great and my pedals all sound great . It does sound like the power supply might be defective.

Your Target sounds much cooler than mine.
As for the thread, count me in the "find a different power supply with a higher current rating" camp.

I live in an old house with no-so-good wiring (ungrounded outlets, etc), and everything makes noise.
If you live in a place with old wiring, too, then that may be the source of your noise as well.

It’ll start doing wonky things like make noise when it starts going bad. |

Wow. That actually looks promising. |
