Hey guys, first off, I am not very sure as to whether I'm posting this up on the correct subforum. Here goes:

I've been reading up on pedals operating on a higher voltage rather than 9V, giving more headroom, cleaner tone, and stuff like that.

Is it safe to run your typical 9V Battery/Adaptor powered effect (say, an Ibanez TS-7) with a higher voltage (say, 12V) adaptor instead?

Cheers, and thanks in advance. =)

I'm not an expert but i don't think you should do that.

Most pedals can handle 12v without a problem. The caps used in them are usually 16v or more and everything else can handle it for sure. A lot of people use 18v adapters with TS9's but a few caps have to be changed to 25v to do so. That said I don't know for sure the caps aren't lower voltage in a TS7! Next time I open one up I will take a look but for now I don't recommend trying it.

Alright guys, duly noted, thanks.

If there's any other info, go ahead and hit it up here too. =)

Lowest voltage cap used seems to be 16V.

i've used a 9.6 volt adaptor on 9 volt pedals, and i've always wondered if it was hurting them, haha. i've noticed the LED usually tends to be a bit brighter.

hmm, you've got me thinking now... how high of a voltage am i safe to go with with my bloody murder? if you remember what voltage caps you used, haha.

its an early one if it matters, #15

Yea, I forgot I had a schematic to look at 16v is the lowest so a 12V adapter should be fine.

They should all be 25v or 50v. There's only three of them in there and I went through a few brands/types when over time. Open it up and look! The cylindrical metal caps are the only ones that matter and they'll tell you the voltage on the side.

Okay, duly noted!

Makes me feel like opening up my landmine distortion to take a look too. lol.

awesome!

thanks!

Hmmmm just thought I'll shoot another question related to the topic.

Are caps the only responsible factor for running a pedal at a higher voltage than usual (of course, I don't mean to the extent of running it at 100V, that would be insane! =P)?

Pretty much. Resistors aren't voltage sensitive and diodes are usually good for at least 50. I don't know the voltage specs on the transistors in that pedal and I'm too lazy to dig up their data sheets right now but they'll be fine. I know for a fact the opamp can handle it.

That's it!
