The best thing I've ever done for my guitar/amps tone...

[bonedarrell]

Put an EP booster in my effects loop and left it on all the time.....awesome!

Interesting thread.

I had a few threads about 1-2 year's ago about Voltage Regulators and Power Conditioners

One was mega bucks and the other a glorified power box


Is this new? thats a good price. I thought they were like 900 USD? (trying to remember)

Keen to hear more peoples opinions and more about this model compared to the others !!

There's a guy on ebay with five brand new P-1800 PF R for 337.49 shipped. I ain't getting one but seems like a pretty good price. I have no association with the seller nor take any responsibility for unseen issues that could come from dealing with them.

Any chance you could post some with/without clips? Seems like half the people I talk to about these things rave about them, and the other half call them snake oil.

TRUE, but I'd love for someone to have done a comparison with some of the Tripplite products that are WAY cheaper than that, that also are Voltage Regulators! Eric

"There is no better protection for a tone snob’s guitar/bass rig"

The reviewer chose his words wisely. For the us non-tone snobs, there are much better/affordable choices

This is interesting to me...

I have ALWAYS found that any power filtration for HIGH CURRENT chokes off power...

It tends to have a smoothing effect, less brash. But Everyone I've ever tried for a high powered amp this for Stereo HI-FI as well that cost up to $5,000 make the amp sound Lame.
They Kill Punch & Dynamics, and make the amp sound dull... I can't believe something THAT small could pass enough current not to limit a high current tube amplifier...

Could you please be objective, and listen when the power is good... But pay attention to not the sound but the Power and punch of the amp. Does it make a lamb out of a Lion?

Thanks,

RR

Your response is also interesting to me but I can't quite follow it.
I'm not saying you're wrong. I can't tell how you came up with these findings however.
Are you saying the cleaner the power, the worse an amp sounds?
Care to elaborate?

I agree with the TS; getting my Furmann made an end to that "why does my rig sound different each time I'm using it" I love it

Giga, which Furman do you have? Thanks

I think it's a 2306 (not even sure). I'm in Europe so 220-240 V and I believe it can deliver 8A max. This goes down as I increase the targetvoltage. I'm running 230V. At our rehearselspace the voltage varied from 205 to 235 Volts and now it's always between 227 and 232.

No, I'm not saying that at all...

What I am saying is that any power filtration I've ever heard on a powerfull high current tube amp has limited the Current... It might sound nicer, cleaner, etc.

But to my ears they always sound less powerfull... Less PUNCH, move less Air Etc.

This is such a compact unit, I can't see how it would not.

Preaching to the choir! I happen to live where the power grid is all over the map. Voltage fluctuates from 119-129V and Hz is unstable as well. The AR and PF series stuff are not regulators in the sense of a variac. It won't limit voltage in any way, just regulates it at some mathematical mean of the input voltage. But, it does remove all the instability of the Hz and smooths things out for surges in power. For regulating duties, I take everything down with a transformer to 110V then plug my Furman into this. So, I get constant 110V, regulated and conditioned power. It's all a small price to pay to protect the power end of pricy tube amps. Without it, trying to bias an amp is a crap shoot, and if you happen to get it biased on the lower end, get a 10V input surge and this translates into a 50 or 60V increase at the plates. If an amp is biased at the upper end, which I do a lot, that PV increase will play hell with tubes.

Ok, I get it. So, is this something you have more or less "heard" on a consistent basis but not really tested?

I hear some crazy stuff that a lot of other players cant.. Differences between two of the same branded tubes is a blind A/B test but I've yet to hear anything along these lines to be honest.
The amps I plug into the Furman sound tighter and cleaner consistantly (If that's the type of amp I using anyway) The gain sounds smoother to me (I think )but not in a bad way.
Do you think that something else in your testing could be throwing this off?

I've never electronically tested this, it's only been my consistant observation. But be aware I've been critically listening my whole life... And To Speak the truth I've never tried one on a Guitar amp... Only HI-FI... I'm an Audiophile, and have tried them for decades on systems that cost as much as what you could buy a small house for.

I Think you are hearing Correctly! You Said TIGHTER, and this goes along with what I have heard also, AND makes sense Electronically. You Are Stiffening the Powersupply. I can hear that on the guitar amps when I put Very Thick 10ga Electrical cord Vs. A small puny one the small one is like a straw vs a garden hose effect when the amp draws it restricts, then the power catches up to demand, and rebounds... So the Thin cord makes the amp Loose, and the Thick makes it tighter cause there is less current variation.

That thing Clamps the voltage, and no loss, and no surge so the amp is Tighter.... Sure. *BUT*, This is subjective if it's a good thing... I think if you like New Metal, Speed Metal it's a great thing having the amp tighter/Stiffer. But to my tastes that like 80's Hard Rock & Metal, I like the Amp Loose. I love the Sag, and being looser, it's easier to play. I know what you mean about Smooth distortion, and I think I would definately like that. But the Tightness definately not.

So you see it's all a matter of taste, as well as electronic theory.

Bottom line If you like it, and it sounds good & suits your playing. AWESOME!

But my suspision that I would not like it, I think has been confirmed.

Thanks!

This is absolutely true, power conditioner/regulators are absolutely necessary, no doubt.

Thanks for explaining that! Your points are well taken.
I can see the positive and negative effects depending on what you're trying to achieve.
This seems to be the case with just about any thing you can add to your guitar rig.
It's usually always a compromise to some degree and it comes down to if the positive effects out-weigh the negatives.

Personally, I can't live without certain pedals in my rig such as a Maxon OD 808 to "boost" the input..
I know it screws with the pure tone of the amp, and it makes it nearly impossible to roll off the gtr's vol. knob for different shades of distortion but to me, it's worth it for the end result.
