Tone Hammer report.
This was my first weekend with my new Tone Hammer DI.
Good comments all around, from sound people, band members, and even audience. I am pleased with the unit.
Both of the buildings I played at have multiple service panels and likely ground loops. Had to go into a passive DI at both places to get rid of hiss. That was with tone controls at 12 o'clock.
It's dead quiet at home, though.
I would be interested in hearing from other Tone Hammer users on this.
Tried the ground lift ?
Yeah, that was the first thing I did while I still had the house XLR plugged into the Tone Hammer.
I'm not alarmed. Have had to do the same at these locations with other preamp/DI units.
I do have to say that so far the Tone Hammer has the best tone for me out of all the other preamp/DIs or "bass drivers" I've used.
I will say that I've had a hiss in my setup using the tone hammer, however I'm still trouble shooting so the problem might not be the pedal (other pedal, cables, etc)
Where you using battery power? Battery power will always be the quietest option also. Some places are just noisey.
Both of these places had old school dimmers mixed in with new, video projectors, flourescent lights, wireless mics, you name it.
It even was noisy on battery power.
So I run a separate DI. No worries. The Tone Hammer stilll rules the roost as far as I'm concerned.
Roger copy on the EMF coming through the bass. I was running single coils.
Just curious here because early on Aguilar did release a batch of Tone Hammer's that had a grounding issue, but I believe they were mostly all found and fixed. That batch though exhibited typical grounding problems, i.e. the noise would increase/decrease by touching the pedal for example.
With the TH disengaged, the pedal should be as quiet as any other quality DI. Engaging it with the EQ flat and AGS, it should be nearly as quiet as when bypassed. Boosting EQ or engaging the AGS with a lot of gain is usually still very quiet in most environments. If you're using single coil instruments though, all bets are off. I play in an environment quite regularly where I simply can not bring a single coil instrument at all, especially if I want to use any kind of pedal/preamp that provides some overdrive. It's just way too noisey. I have a couple of jazz basses equipped with Dimarzio Area J's for those applications though, and things are dead quiet when using them.
Love the single coil tone. Hate the interference they pick up.
What I did to quiet it down was run the 1/4" out from the Tone Hammer into the 1/4" passive DI input. The house XLR was plugged into the passive DI. Even then there was a very slight "hands off" buzz at the bass. I wrote it off to buildings I already know are noisy. I didn't have the AGS on at all.
I don't think there is anything wrong with the Tone Hammer.
But I will check the touch buzz to the case next time around.
I had some hiss/buzz come through at a rehearsal space I was in a while back, but that was with or without using the TH. Otherwise, I don't recall any issues.
It's a great unit, though I don't currently use mine. I bought it primarily to sweeten up the tone I was getting through an Ampeg SVT4 Pro/Classic HLF410 rig. Since moving back to my old Ashdown 210 EVO II combo I haven't needed to add the extra warmth.
The hissing you hear from your stage amp was likely caused by running the Tone Hammer (or whatever final pedal the TH is in line with) directly into your amplifier input. That means that it goes through your amp's preamp, which bumps the line level signal being generated by the TH up by a factor of X (X=the gain of your preamp). This is quite common and I see it a lot with preamp pedals like the TH.
I would suggest running the TH into the effects return of your amplifier, which should bypass the amp's preamp and the TH will function as the preamp (which it should, in this case). You'll ultimately get a cleaner output without doubling the tone controls along the way to your amp's final stage.
As far as buzz goes, if it's a ground loop, you'll have a VERY loud buzzing from your amp if there is a ground loop (common in remote board situations). Engage your ground lift button and all should be well.
Any buzzing that is calmed by touching your strings is likely coming from a combination of a badly grounded outlet that your equipment is plugged into (a ground wire that is too small or has come loose in your amp or power cord or somewhere along the way to or even at the power outlet) and some hot pickups on your guitar.
Hope that helps.
Ground loops are caused when any two pieces of equipment that have different power sources, ergo different paths to ground, become electrically connected. By different I mean that each device will use the most efficient (closest) ground connection for itself. Ground loops are everywhere, constantly, and we only hear the 60Hz (U.S.) hum/buzzing in music production because we are amplifying the signals to an audible range.
A good way to look at this is to think of the device whose current draw is smaller (the mixing console) will become a 60Hz tone generator for the amplification device, whose current is dramatically larger. The tone, which is a buzzy hum at that frequency, is caused by the electrical activity of the power just doing its thing at the mixer, going in a circuit between source and its (closer) ground. It gets imposed onto the signal wire because all the grounds are electrically connected, hence the term "loop".
It's the type of wiring AND the proper connectors that are used that determine if you can eliminate amplifying the hum, regardless of what type of connector you're using. Balanced wiring needs balanced connectors, of course, but those aren't generally used on guitar jacks and instrument cables, but they absolutely are everywhere else, from all signal cables from mics, DIs, pre's and everything else going to the console. When using balanced wiring (which you always should) engaging the ground lift on a DI box disconnects the pin 1 shield wire from the circuit, thereby eliminating current flow along the cable shield between the two devices (DI and mixing console) and subsequently isolating the 60Hz tone buzz being created by the normal electrical activity of the source of the signal amplification.
Make sense? Now you too understand! Rock on, bros! :D
I was running direct to the PA, ground lifted, and not lifted.
As others have stated, there's multiple ways for ground loops to happen, even equipment plugged into different phases, especially if the building has a 208Y120 service.
And honestly, I think the buzz/hiss is from things like dimmers, other stage amps, poorly bonded panels, sub panels with improperly connected neutrals and equipment grounds, failing water heaters, flourescent lighting, fan motors, air conditioning and/or refrigeration, and even PCs. And last but not least, the quality of a particular DI, like whether it has a good or any transformer. And I WAS using single coil pickups.
This unit is dead quiet at home, even plugged into a combo amp input.
And I've had other preamp/DIs buzz worse. We have no control over what the house power is like.
