jam man pedal broken

[paul]

I have a digitech jam man looping pedal. the stop pedal doesn't work
sometimes, but it's kind of an infrequent occurence. a few questions:

1) can I fix this myself? I have basic tools, not sure what parts I
would need or how to take the pedal apart, although I'm sure it's not
rocket science.

2) anyone know anyone in NYC who fixes stuff like this? iirc the pedal
was at least 300 bucks so it's probably worth getting it fixed.

By "doesn't work", do you mean it just completely turns off sometimes?
If so, it might be an easy problem with the power. Does it make any
difference if you wiggle the power wire or use a different power
supply?

I just mean that pressing the "stop" pedal doesn't stop the loop. I'm
guessing it's some problem with the switch mechanism.

back in the day, the switch on my wah pedal would wear out from all
the forceful stomping. I could easily see it being as simple as that
with the jam man. If so, it's a simple fix if you can locate the
right replacement switch. I would definitely open it up and test that
switch if you can.

ok, follow-up. For kicks I just pulled the back off mine. Very easy,
just those 4 allen screws. The switch is actually just a very small
little componant soldered into the skinny little board you'll see at
the bottom when you're looking into the open back.

one of three things is probably happening:

1) switch itself is bad. Should be an easy fix with a soldering iron
if you can find a replacement. I'm sure at some online electronics
place it'll be about a buck.

2) The board has somehow dislodged so that stepping on the pedal no
longer creates the mechanical contact point with the switch. This
seems possible but unlikely. But it would be the easiest fic too.

3) over zealous stomping cracked the board. Worst case scenario also
seems unlikely.

Probalby # 1. That little board lifts right off its mount enough so
that you could pull the switch out easily after melting the solder
joints. Same goes for putting the new one in.

If that's the only thing wrong with your pedal you should be able to
fix it this way easily, the hardest part might be finding the
replacement part. But I haven't looked around, maybe that's easy too.

Another possibility is that the solder joints connecting the switch to
the board have become broken from stomping. In this case, merely
reheating the joints with a soldering iron might solve the problem.

If it's the same as the Boss pedals there's a rubber bung which presses on
the switch. If that's got compressed or lost its elasticity then the actual
switch below won't be pressed in the same way as when new. Either way you'll
be able to tell if its the switch or the rubber part which is faulty.

thanks kevin, I cracked open the pedal and determined that it is in
fact a bad switch. I'll order a switch and a soldering iron.

damn, usually I am good at googling but I have no idea what to search
for here. "effects pedal switch replacement" and similar aren't
working out. anyone have any ideas, or a better term? I'm trying to
replace the small switch that's soldered to the circuit board of my
pedal.

Some of these are momentary and some are latching. Usually momentary is
used, but they're cheap enough to get one (or more of each) when ordering.

If there is a part number on the switch, Google that. Or try
contacting Digitech. They might sell replacement switches. It might be
very difficult to locate the exact type of switch otherwise.

I ended up emailing digitech and they gave me the part number, which
is 44-0077. and you can order it at the online outlet store under
Resources>Outlet Store>Switches at www.digitech.com.

cool, should be pretty easy to replace. And cheap too!
