Running the Jam Man off a power supply

Which JamMan do you have? The one with the vacuum-style switches or the one with the pad-style switches?

After the first year of production the vacuum-style JamMan Stereos were made to be able to accept either AC or DC. Look for the manufacture date on the bottom and we'll see which version it is.

 

Don't do it yet, let me find out on Monday if there is an easy way to tell which one you have.

 

I just found out this morning.

The conversion took place in August of 2012. According to the engineer, if you are unsure if it is the new version it won't hurt the unit to plug in a 9vDC PSU to check. It will either work or not.

The JamMan Stereo uses <9w, which at 9vDC comes out to 1000mA max. That's far too much for most supplies (the PP2+ has 250mA max from two of its outputs, and 100mA max from the others).

 

Ah yes, good catch. Make sure your DC PSU has a robust mA rating since it does draw some current. It's not quite 1000mA, but it's close.

 

Anyone know how to date a Jamman? Do they have a build date stamped on the pedal?

 

When I was looking into this, I decided I'd be safest going with a PSU that had a courtesy AC input that I could plug directly into - and had just about settled on a Cioks. Then I bought a EHX 360 nano looper instead, which has more ordinary supply demands, is much smaller and covers most of my needs when I'm out of the house (in the house, I still use the Jamman sometimes but less and less) - including saving loops. Unlike the Ditto, the 360 will save 11 loops.

 

It is one thing I wish my Jamman Stereo would do is run off of DC (it was almost the deal breaker for me since I live off the grid), but I would not take a chance unless I was certain that it has the updated modification. I just might pursue this though.
After August 2012 at 1000mW dc?
