Powering my (loop) pedals from the amp...

[mcinku]

I thought I would ask you guys before I destroy my amp...


The goal here is to get 9V for my delay and reverb pedal and the question is, would this work... or is this even a smart thing to do.

My two cents: why would you want to? Just find yourself a cheap wall wart and a multi-ended extender. I use one of these: http://www.visualsound.net/1spot.htm

Works great, and still works great if you decide to gig another amp. I'm all for diy but sometimes you're just reinventing the wheel, and in this case, seemingly in a way that makes it less useful, not more.

I did exactly that on an amp I built for a friend. He built a foot pedal with a 9V jack on it and has his entire pedal board powered from it. Works great and has not blown up anything. Just make sure the xformer can handle the current and you're golden.

Well... I would like to minimize the gear I carry around... and when I set up my gear I want it fast and simple...
So my idea is to make a board containing Klen, delay and reverb... and when I put that board on top of my amp just plug it into the amp itself... quick and easy

So I'm on to something with this...

What I would do is install a female AC outlet on the back... plug in a small wallwart.. If you do it your way make sure your regulator can also handle the added current with everything running...You might have to heat sink the back of the regulator check it for heat...Should work fine!!

You have seen the pedal snake cables right?

Neat idea but very expensive to implement.

The snake carries audio to and from the front end as well as in and out the FX loop, as well as power for the pedals.

That voltage regulator can take 1A which is more than enough for everything... but I'm not sure how much current that power board before the regulator can put out.

Any ideas?

Be carefull not to cause a groundloop! The 9v power cable provides a ground to your pedal, but so will the guitar cable! I've had the same thing with an fx loop switcher I build. I had to use separate windings from the tranny to make the 9V, with a "floating" ground.

Looks interesting but my way, is way cheaper.

I had same issue once, with an ab switch I built.
I guess I'll see what happens, if I decide to go for it.
