Just bought a Pitchblack off Marshall. Good guy to deal with and would happily buy from him again

Cheers chaps, plenty of great advice to think over here

Hi there everyone, I'm looking to buy a pair of headphones for monitoring music production, monitoring recording and the like. My budget isn't massive so something fairly cheap and cheerful but but will give a clean unbiased sound reproduction if possible. Any advice would be greatly appreciated!

Great seller, bought an Ibanez Roadster II and it's great! An honest chap who let me let me know what was going on every step of the way. You can deal with John with total confidence. Cheers mate

Just bought some pups from George, a nice chap didn't want the earth and got them to me quickly. A pleasure to do business with and I'd happily do so again!

Bought some pickups from Alan. Top man, came super fast and very well packed. I can't wait to set them up. Cheers man

Dave, I emailed Zoom about this issue. Does it happen when you use headphones or an amp? They told me it will buzz through headphones because they are not grounded and the unit does not ground itself. I also started this thread in the effects section where amongst other things I've recently Posted Zooms response to my buzzing query. Hope it helps!

It does, yes. Nice they answered quickly and actually gave a decent explanation rather than a dumbed down fobbing off some companies try!

I emailed the zoom people with regard to this and I got a response from the engineer The low volume buzzing he describes is almost certainly due to Zoom's use of a switch mode type power supply and his monitoring the output via a headphone. This type of supply is not grounded as is evident by the use of a solid plastic earth terminal on it's supply connector. Also to conform with electrical approval and CE compliance the output negative connection is normally decoupled to the supply neutral, albeit with a very small value high voltage capacitor, which promotes a condition know as standard mode rejection. All switch mode unearthed class 2 supplies do this and the solution to the buzz is to have a ground connected to the B3 via an output screen connection. This is what would happen normally when it is connected to an amplifier via a guitar lead. The USB connection to a PC would do much the same as it connects the B3 audio earth to the low impedance ground plain of the computer's. All manufacturers are now using switch mode supplies for DC regulated supplies as the price of copper for traditional transformer based adapters is at a premium. This is unlikely to change in the foreseeable future.

Oh ok, so do you reckon the unit is faulty then? Sorry for all the questions!

Do you mean a grounding issue with the B3 as opposed to grounding on the guitar?

Thanks for the replies! It's not being daisy chained and I'm using it's own psu that came with it. Unfortunately I don't have another psu to try to eliminate that but I'm thinking whether to buy one as a back up, the original seems like kinda of flimsy, can anyone recommend a decent one? I bought My B3 from guitarbitz which seems a decent company but they don't have any more in stock so it would probably be have to be sent off for repair if it is faulty. Which is a bummer as I really like it otherwise! One thing I've thought of, each time I use it, it's been on a strip socket multi plug type thing. Could that possibly affect it?

Hi all, I've recently bought a zoom be and it's great apart from one thing, it's pretty noisy. At first I thought maybe the guitar needed more shielding as when I touched the strings the buzzing stopped to a large degree but it seems it may be the power supply as when I use usb power the buzzing stops. I can even power from the plug and as long as I have the usb also connected up to my PC there's no buzzing. Also if I put in a shorted Jack in the input and have a normal plug power without usb it's ok. The buzzing also stops if I hold parts of the case too. I've tried a couple of basses at a couple of different places and same result. Has anyone else had this happen and is it a faulty power supply? Any advice appreciated as it's driving me bonkers!

Olliedf89 sold me a pedal and it arrived super duper fast and in bomb proof packaging. Top man

I think I may have a similar problem with a zoom b3. Silly question but what is a shorted Jack? I'd like to eliminate the guitar out of the problem!
