Quote from thebrushwithin

FWIW, actually he he has two AxeFX and one KPA.

You´re absolutely correct. I watched the video again and Adrian has one of each in the studio and in the "Magic Closet". The second AxeFX must have slipped my attention ... gee, I wonder why.

Quote from viabcroce

Mhhh... your post has made me think

I just ralised that he is one of my favourite musicians, but not guitarists, if this makes any sense.

I fully understand you. There is a lot to learn from Adrian music wise.
In interviews he also always (sort of) braggs about that Frank Zappa (one of my favourite musicians ) told him how to survive as a musician in the music business (Frank was an extremely clever guy in this matter). Adrian never spread the word what exactly this was, but if you follow his career, you might get a hint on what this was.

However, back to the thread subject ...
I should easily imagine that Adrian actually prefers the KPA over the AxeFX, but as he is constantly into reducing his travelling gear (which is understandable as shipping/freight costs within and from the US are completely ridiculous), the AxeFX may offer the best "live" compromise to him for the time being.

However, two KPAs and only one AxeFX 1 in the studio tells you something ...

There seems to be a rackmount KPA right before the end at 14:51 back in the main studio room.

Adrian is one of my favourite guitarists ...

Hey revilo,

thanks for resuming this thread I had forgotten LOL

I'll try and get the sources for the researches I was referring to, ASA I remember where I wrote it down

Ciao Gianfranco,

yes I forgot about the thread too, until I read that tube amp book ...

Here´s a little PDF that covers a scientific study about the effect of high frequency components on the human brain and which is also used as a source in that tube amp book:

http://jn.physiology.org/content/jn/83/6/3548.full.pdf

Scroll down to the last chapter if you don´t want to wade through the whole study.

This interesting subject may explain why sample frequencies of 48 or 96 kHz often are perceived with a distinct noticable difference in sound.

edit: The last sentence should correctly also include 192 kHz sampling frequency (or 176,4 kHz for HDCD or 352,8 kHz for SACD)

Quote from viabcroce

It has been proved that humans don't *hear*, but actually *perceive* ultrasonic sounds. We use other organs for the purpose.
The difference is meaningful indeed, but inplications are such as well.

Hi Viabroce,
you were certainly referring to this matter:
http://en.wikipedia.org/wiki/Psychoacoustics

I was reading a book about tube amplifier technology the other day, when I came across a chapter about Intermodulation Distortion (IDM) with these two quotes that I would like to add:

1).
"The brain electrical activity mapping experiments show that high frequencies above 26 kHz in Gamelan music are able to induce activation of a EEG that persists in the absence of continued high frequency stimulations".
In other words, if you expose someone to high frequencies, certain brain patterns will be activated which continue to persist when the reproduction of these high frequencies has stopped.

2).
"The results from the subjective sound quality evaluation experiment by Scheffe´s method indicated that the music containing high frequency components was perceived as more pleasant and rich in nuance than music from which high frequency components were eliminated".

I know this is probably outside the scope of what the KPA is meant to do; but it's something that I do quite a bit on the AxeFX -- having the ability to load up two different amps and use a CC pedal to roll between the two would sure be awesome. I mean, technically, it's still considered a "rig" right? Some guys use two amps in a rig...the same would be nice here. This would really only be super useful if more advanced midi/CC control were implemented.

I totally agree with you in regards of two parallel stacks (amps). That should be a feature of a future firmware update and I do not consider such a feature at all to be "outside the scope of what the KPA is meant to do".
I think this should definitely be INSIDE the scope of the KPA in the future !

The editor will come some day, I am positive about this. It would be disappointing if it doesn´t with such an excellent product.

Regarding iPad control:
I once had the spontaneous idea of a 19" KPA with only 1HU and the six pots (plus a few other controls that should be and could be laid out on a panel of a stripped-down rack version), but controlled via a tablet or laptop computer.

Well, this may even be something worth considering ...
One could then mount this 1HU KPA in a rack or an empty amp head shell which would even have additional space to house power amps, mounted ("invisibly") from the backside and on top of the 1HU KPA.

Two parallel stacks (of course with two different profiles) and a simple blend mixer at the end

The person who is happy to stroll along a street listing to music from a squeaking mobile phone speaker can never be won for 192 kHz-technology. The same applies to the ordinary music consumer.
This technology is for knowledgable people (or with a certain "awareness") and with a particular interest.

The same applies to audiophile HiFi, vinyl records, the KPA, a handbuilt boutique amp or instrument.

However, don´t get me wrong "ampjunkie" it is still an interesting article to read, although I have another point of view on this.
I have listened to 192kHz recordings as well as music through a 192kHz converter and to me (perhaps only placebo effect ?) it sounded like a master.

There are people for who a 4x12 box with Celestion Vintage 30 chassis is the ultimate electric guitar sound reproduction, but there are also people who feel that a FRFR loudspeaker with a frequency range up to 18 or 20 kHz offers the best sound projection, just because they know (or believe to know) that there are overtones in the electric guitar sound that are above the 5 kHz that a Celestion V30 can deliver.

For those who worship a 4x12" box with V30s, a good FRFR speaker system will sound "too HiFi" and some of them would ever never think about buying such a "ridiculous digital thing" like the KPA.

Of course this is yet another subject that can be endlessly discussed, as there are as many opinions as there are thread contributors.

Quote from ampjunkie

I would agree -- tube amps have their place and are nice to have. Not just tube amps though. The Pearce G2r combo SS amp is killer.

Regarding turntables and vinyl -- I'd be interested in the demographics of who's buying those. If I had to guess, it would be the baby boomer crowd with a huge dose of nostalgia -- not the millenials.

The 1 million figure comes from a recent annual report of the German phono industry association, the 2-figure percentage also (as well as magazine articles). I am following this subject with interest for quite some time.
Even large record stores stock up their vinyl offer every year, it is not only the small specialist record shop anymore that supports vinyl records ... and this is not predominantly electronic music anymore either.
Almost every "important" album (sic) release in these days is also being released as a vinyl record. This would have been unimaginable 5,6 years ago.

Actually a large percentage of vinyl buyers are people in their twenties and thirties, so not really the baby boomers (who actually show a declining interest in vinyl).

The Audio-CD is dead.
Try to get a decent CD-player in your electronic chain store these days. It is almost impossible. You can rather go to a thoroughbred HiFi shop to buy one.
Philips has stopped developing CD-drives (which also affects audiophile manufacturers who relied on their drives for their own products).

So it is either audio files or vinyl in the near future.
The 192 kHz technology however is an interesting trend to keep an eye on in regards of digital music.

"For there is nothing good or bad, but thinking makes it so".
(William Shakespeare)

However, this discussion reminds me a little bit of the introduction of the Audio-CD in the early 80s. Back then everbody wanted the CD and thought this is the future. Many immediately sold their vinyl record collections.
Now the vinyl market is gaining in the 2-figure percentage range annually and over here in Germany 1 million new turntables are being sold every year over the counter.

Those who feel to sell their amps should do it, but I think tube amps will still keep their "raison d´être"... despite the KPA (or Axe-FX).

I buy CDs but I also buy vinyl records (if I feel an album is worth it ... not each one is...) and I have never sold my vinyl records.
I love my KPA but I will never sell my (Pre)Amps either.

It´s a matter of taste ... and how and where you want to use your KPA (or Axe-FX).

No Problem Revilo, glad I could help.

Ok, the Summer sale will last until the end of August..

And I will hopefully (trying my hardest, to get it released next week) so you all get to have a discount at the same time! : ) - everyone wins!

I'll keep you all updated as I go anwyay!.

Thanks Andy!

Yes, so much to do, so little time ... and it is summer that wants to be enjoyed as well ...

Looking forward to your sale and particularly the new profiles ...

Oliver

Hi Andy,

thanks for your explanation on how you approach your profiling.

Just in case you misunderstood me, it was not my intention to criticise your way of making profiles, it was just a question out of curiosity.
It will never keep me off from buying your profiles ...

BTW, how long does your summer sale last ?

Cheers

Hi Andy,
how do you see the chance that you will offer profiles in the future that have been refined with Humbucker and single coil pickups seperately ?

I find it does make a difference if one plays a profile with a SC guitar that has been refined with a humbucker guitar (or vice versa).

What are your thoughts on this?

Quote from and44

Yeah some of those are good..that I might use (don't sue me lol)

Don´t worry Andy, they´re royalty free ...

As well as these:

Kornfeld (I like the idea but would suggest a teutonic "K")
Mesa Boogie = "MoBee"
Laney = "Lonnie"
Bogner = "Bagnrrr" or "Boner" ( ... sorry) ... "Boner Goldmember" ... ... oh, shut up ...
Diezel = Kerosene
Divided by 13 = "Friday the 13th" or "Lucky Number" or "Lucky 13"
Hiwatt = "Say What?"
Vox = "Voice" (Duh ...)
Redplate = "Red Anode"
Selmer = "Thelma"

Enough brainstorming for today...

So, you´re heading up Norwich ... nice historic town centre ... and Northern Norfolk is a beautiful area as well. A good friend of mine lives in a village outside Norwich ...
Have some lunch at the "Lighthouse Inn" in Walcott and order smoked mackerel sandwich ... yum.

Quote from and44

Yes this is true!..They have been snapping at my heals for a while now..I thought it was over, but they came back with other quirks they had..so in the end I decided to change it totally to keep it all satisfied, and also everything else while I'm at it!...ironic really as marshall are the ones who supplied me with a lot of the amps. and they knew what I was doing!..and loved the fact that you can "catalouge" some historic amps. - ah well!

Finding names are very hard lol.. they just look like garbage most of the time.... least we have "Seeking to re-create the sound of " still.. least we can still understand it then

I completely understand this, Andy.

However, although highly entertaining, the story about Marshall is a bit bewildering. Perhaps they have under-estimated the KPA in the beginning and now realised the extent or impact of it for the music instruments industry (which is generally struggling for quite a few years).

I for one (who has an innate bias towards provocation ... well, casually), would have chosen "Mosh All" for Marshall ... "Lemon" or "Tangerine" for Orange ... "7ender" for Fender and so forth

I can recommend to check the European patent office´s website for word mark copyrights.
I think the "Intellectual Property Office" in London offers something similar on their website.
I should imagine that there are some "word marks" with expired copyrights that you don´t have to worry about anymore

Cheers

Looking forward to your future releases, Andy.

BTW, I have noticed the other day that Marshall seemingly has given you a bit of a headache by making you not use their name for your profiles anymore.
Your "UKGold" profiles now merely are "seeking to re-create the sound of a Marshall" amp ...

Goodness, they must be frightened
