Noise Issue

I currently use the hot rod deluxe amp for gigs.. and I have a noise I can not seem to find which is rather loud and an anoyance to me and even at times the audience will complain.. the noise only occures when I am in the full boost position with my guitar set at any of the 1 3 or 5 positions... (useing fender strat guitars) while I am in the 2 or 4 position there is no noise and it happens with any of my 3 fender guitars. I also have a gibson LP standard and a PRS, neither of these guitars in any position make the nosie... sort of like its an odd phasing issue.. also.. the noise does vary according to my standing position with the amp.. worst areas are the sides Lt and Rt.. or dead center, moving around can sometime elimanate the noise..

It has me concerned and it is a problem I can not live with. so please help with advise if possible

thank you

your problem is the pickups are making the noise,you can shield the pickups with foil,or get noiseless pickups,or try a noisegate between guitar and amp,it is quite common to get pickup noise with alnico's,where as humbuckers you wont get noise issues.

You may want to get a high quality cord. Also if you have a cell phone on in your pocket, that can cause all kinds of problems. I had to change the preamp tubes to tame all the noise in the drive channels. A noise gate will change your tone. Single coil pups in general are a bit noisy. If you couple that with the cheap tubes that come stock in the HRDlx, the noise is just off the hook. I always cut the volume on the guitar down a little bit when I use the more drive channel.

thank you so much for your imput... I use wireless... and also cords no difference... so I'm going to rule that out for now...

but I am goin to try the pickup isolation.... I found a few packages made of copper...

might take me a couple weeks to get it done... but I'll report back

again I thank you

Noise was found, believe it or not, the problem is with having power converters such as wireless, effects panels, drum preamps and etc.. if they are used in the same line either in your set up or within the building or source line seems to trail back, efi's did not help, keeping the amp powered on a line seperate from any such devise and I am noise free.

thanks for past advise

Using a good power conditioner is always a good idea too. Lots of clubs have less than ideal stage wiring. Sometimes you have no choice but to have your amp/effects plugged into the same circuit as everything else.

From everything that I understand a power conditioner IS a voltage regulator, that is part of it's power conditioning, not a power STRIP.
I use a fulman, and so far it's worked well, but does little to nothing for noises that I've had to deal with. Line shock is something that has been around forever and yeah it bites like hell at times, but usually a line reverse will cure that problem, the only time that's a issue is with older wiring with out a seperate ground or not being wired correctly. 2 prong connector instead of 3, in the modern building all those grounds go to a common buss, in older buildings with 2 prong connectors you'll need a line reverse, which most modern equipment is no longer equiped with, so it's something to be carefull of, but in the whole it's not that terribly dangerous unless your standing in water, it just bites a lil bit Razz

If you have something on the lines of the Furman AR-15 or their P1800 AR, then it is a voltage regulator. If it's the PL series, it's just a "power conditioner" that doesn't do anything for voltage sways. I don't know what you have and you may have the right gear, but a lot of people buy the wrong gear for the wrong reasons. A plain old power conditioner, be it from Furman, Monster, etc. won't do much for voltage swings.

As for noise, it's one culprit to look for. If you can eliminate power as an issue, it's then got to be the gear.

Using a line reverse (I'm guessing you mean a ground lift) isn't the best idea, although sometimes they are needed. Best to figure out the problem at the source.

As for not being terribly dangerous, better safe than sorry, and no, you don't have to be standing in water to get shocked -- two different grounds connected through you will do it. I'd rather not be shocked.

It's also worth the $4 to go to Home Depot and get a circuit tester - plug it into an outlet and it tells you if it's wired correctly. You'd be surprised how many clubs, bars, pubs aren't. Worth protecting you (and your amp).

Get yourself a Hum Debugger pedal by Electro-Harmonix. Or at least try one out. I got one and it works great.

They do work well, as do the ebtech (now morley) devices.

If everyone can plug into the same circuit, it eliminates a lot of this noise to begin with.

the noise is coming from the single coil pickups. it's natural. if you want to rid the noise, install humbuckers or noiseless single coils, or run a noise surpressor such as a BOSS NS-1, or MXR Noise Gate. run one of them through the effects loop of the Hot Rod Deluxe. thats what i did on my Hot Rod and it worked great.

Ahh - unlike me, you read the OP and saw where the problem started...

Fender Noiseless are good; I installed Duncan Duckbuckers on my MIM strat and it cut down considerably on noise.

On one Tele, I have Duncan Hot Rails front and back with coil taps and minimum noise; on another Tele I have Duncan 59 and a JB, also with coil taps. Better pickups and shielding will give you less noise on singlecoils.
