How Dumb is This?

I picked up a Marshall GV-2 cheap at a GC sale about a year ago and did my usual thing of opening it up, taking a look at the circuit, satisfying my curiosity and chucking it in a drawer, where most stomps belong.

I was looking through my stuff and found it yesterday and remembered there was some mystery about it, then I saw what it was again:

The instructions for using an AC adapter are contradictory.

It says in big letters to use "9V NEGATIVE GROUND ADAPTER," (like keyboards) but the diagram shows the usual stompbox 9V positive ground. The print instructions further obfuscate the matter by saying it uses a "9-volt positive adaptor." Positive what? Pin or ground?

Jeeze, what numbskulls. So, does anyone actually know which grounding these pedals use?

It's a Marshall so it's made in England by people who don't even know that the Queen's English far less being able to speak it!!

Either that or it's made in China with the instructions being wrriten in Mandarin, then being translated into Korean and then re-written when the pedal eventually gets as far as the Marshall factory in England.

Maybe you're best to use a battery!

If you're the guy who pops it open to look at the circuit anyway, just look at the wiring and see where the power leads go from the battery and the plug.

It's normal. The label was wrong.

Heres where my snobery will come into play.
It being a marshall should have stayed in the drawer.
I have yet to find a Marshall product that has appealed to me.

And that was a grammatically correct sentence, was it?

Though you do have a point. Most kids leave school unable to read and write nowadays! :rolleyes:

GV-2 = 9V DC centre -ve 2.1 barrel (Boss Conventional)

If you go to this page (http://www.diago.co.uk/pedal-power/pedal-power/instructions.html) it shows diago's adaptors and their colours - select compatability under "Pedal Power" in the menu and it lists many of the world's pedals and their power requirements. Usefully it also mentions the mA current draw of many pedals too.

I always go here when in doubt. Hope that helps
