I recently acquired an older DOD FX70 Flanger pedal. It's a basic simple flanger, which was all I was looking for and works well with what I want it to do. There's only one thing I don't like about this pedal. It's the 1/8" (3.5 mm) jack for the DC power supply.  It calls for a 10vDC power on the tag, but if it runs from a 9v battery I'm thinking any 9v 250mA power supply would work. My question is, has anyone swapped out the 1/8" (3.5mm) jack for a conventional barrel type jack on one of these old DOD pedals? Did it work? Any special things or gotchas I need to consider in making this swap? Happy Trails Cynical One |

I assume "older" would imply no PCB inside, or at least not one to which a power jack might be directly mounted. If the power jack is mounted directly to a board, it may be tricky to remove/replace it.
But the more basic question is "why"? It would be a whole lot easier to either:
1) Rewire a new 1/8" plug onto your chosen power supply OR
2) Make a 1/8" male-to-barrel plug female adapter OR
3) Use a 9V battery clip to give you the two power leads running out through the battery door, and wire to the power supply.
With any of those methods, no modification of the pedal itself is needed. The only reason I can think of to swap out the jack inside the pedal would be if you were gigging with it, where reliability would dictate fewer connections.
But for home/studio use, I'd just make up an adapter. That way, the adapter could be used with other DOD pedals in the future should you buy another.
I have an old DOD Chorus with the 1/8" power jack. Luckily, my Godlyke daisy-chain power supply came with exactly one adapter to the DOD style jack . . .

With the 1/8" socket, is it -ve to the sleeve, and if so, is that conected to or insulated from the case?
The Boss-type barrel connectors that Ive bought are bulkier than most 1/8" sockets, so that may be an issue. I'd do what newey says.

AFAIK all the DOD pedals have that 1/8" jack.* It's always positive tip and the sleeve will not be isolated from the enclosure.
There's no reason you couldn't replace it with a Boss-style jack, but I have to second the "why". To be compatible with your existing power supply it'll have to be negative tip, and therefore isolated from the enclosure. You'll have to resize that hole and either use one of the more expensive all plastic jacks or devise some other scheme for isolation.
I personally prefer the 1/8" phone plugs. They are much easier to solder than the Boss style when making the power cables. They also snap into place a bit better when inserted into the jack, whereas it's really just friction that holds those barrell things in.
*Except the really old ones with the 1/4" power jack. Pretty sure it wasn't till Digitech took over that they started using the Boss-style.

I've got the DOD Thrash Metal(hot pink) and just made up a 3.5mm to 1/8" adapter. Not much room under the hood to change the jack. Everything is hard wired also so be careful if you haveto remove the board for anything. The in/out jacks are a pain butt too. They're molded to fit the interior contours of the case

Well there was one answer here which kind of tried to answer the actual question ... but failed. I mean, the question really wasn't which kind of a cable/connection one should start manufacturing but just how to make an effect box have power and make noise - even if you don't have any tools or capability to make some f...king cables or connectors. So please - how would this work, without making your very own and special cables? Are there some adaptors? What? Thanks!!  |

Haddock- Hello and Welcome to G-Nutz2! Your post seems to have a bit of attitude, which you should dial back. Cynical1's original question was not how to power the pedal without soldering up a connector. He was contemplating going into the pedal and replacing the 1/8' phono power jack with a barrel-style jack. He asked if anyone had done that modification, and whether it would present any pitfalls. I suggested that it would be difficult to do so if the jack was mounted to a circuit board. I suggested it would be easier to wire up an adapter cable. Others pointed out the added pitfall that the negative signal was contiguous with the enclosure, and that it would need to be isolated from the enclosure to use the barrel-style jack if it were wired with the tip of the barrel as the negative, as per the usual Boss practice. So, I don't see were the original question was not fully answered. Apparently Cynical1 was satisfied, since this thread is well over a year old and he hasn't re-enquired.  To answer your (different) question, I know of no commercially-made adapters to do this. |

My (modern) TS808 came packaged with just such an adaptor. Maybe the Ibanez distributors in your region could help?
