Always on plug

Just take a 1/4 in jack and short the tip to sleeve. On the vintage ones it's an RCA jack but the concept is the same.

 

^^^^^^
I haven't looked at the schematic, but those switches use a TRS plug for reverb and trem. Would using a regular shorted plug to the sleeve not also shut off the reverb?

It may be necessary to get a TRS and determine whether the tip or ring is the tremolo and short only one of the terminals.

 

Milocj you're probably right. I was thinking they just changed from the two RCA plugs on the originals to two 1/4 in jacks. But one TRS plug would make more sense. (I only mess with the smelly old stuff)
In that case you'd just have to figure out which part of the sleeve to short to the tip. The one that doesn't kill the reverb.

 

Tip is vibrato - ring is reverb - here's a section of the schematic blown up for you.

From my balanced headphone cable page:



Connect the Tip and Sleeve to turn tremolo and reverb on.

Just saw this on CL - someone is probably making good money by taking advantage of the soldering iron-challenged:

Just because it hasn't been said yet... you can't use a standard 1/4" jack because the reverb (ring) would short and disengage when you plug it in. The reverb is already "always on" with these amps.

1: You need a stereo plug
2: short out the tip and sleeve (one tiny wire)
3: Plug it in... and both the vib and reverb will be engaged at all times.

It's the first thing I did when I got my DRRI. I didn't need footswitch control, I just want access to the trem when I want it.

Saw them on the Minneapolis CL this weekend. Really ten bucks isn't bad for someone that can't make their own.

 

Just get a right angle plug like those on Craigslist and put a wad of aluminum foil in it you have a shorted jack and your tremelo will work.
I keep one in my tool box for testing amps missing their footswitch.

 

That will kill the reverb in this amp because of the dual use jack.

 

Robrob, Yup, your right I missed the amp model he was talking about. It will work on some other Fender amps with seperate jacks
.

 

I think I came across the wrong way Rob.
Absolutely, as always your explanations are dead on... I was actually referring to a reference earlier about a 1/4" plug... and was trying to stress that it absolutely needed to be a stereo plug.

 

No, if anybody came across wrong it was me. I didn't need to make that post. Sorry.

 

Look at this on eBay http://www.ebay.com/itm/181839887452

I use these. No affiliation.

 

That won't work for the OP's dual pedal.

 

Stereo quarter inch male to mono quarter inch female adapter? Otherwise a dummy plug would be fine.

 

The ebay item you linked to is a mono plug with a switch installed. The OP's dual footswitch uses a stereo TRRS plug. You have to leave the reverb connection open but short the tremolo to have both effects on.

 

Unless you already have a soldering station set up and ready to go, have solder and and buy the plugs in bulk quantity and have a use for the remaining ones, it's going to cost you $6-8 for that first plug PLUS the time to set up and tear down from soldering, any materials, plus whatever time, mileage and gas you spent shopping for the plug, plus testing time. Nothing wrong with making your own if you're so inclined but it really doesn't make *economic* sense to make a single plug, unless you value your time well below minimum wage. Not to mention about 50% of novice solderers will end up with a cold solder joint on the ground...due to cheap soldering iron and poor technique.

Better to buy one for $10 and be done with it...and spend your time on practice and play, in my opinion.
