[edit] Modelling amps:most common forms section
In the Most Common Forms section it states:
"With the advent of microprocessors and digital signal processing in the late 1990s, "modelling" amps were developed that can simulate a variety of vintage amplifiers' vacuum tube sounds without the use of vacuum tubes. As of 2005, these modelling amps account for a minority of amp sales"
Is there a source for the sales data? I worked in a 20 store chain in New England for 4 years, and Line 6 was one of the best selling lines. During the 2004-2005 X-mas season we coudn't keep the little 15-30watt jobs in stock. maxcap 16:15, 8 August 2006 (UTC)
I removed the statement. "Minority" is meaningless; would need to list % of tube amps, solid-state amps, and digital modelling amps. MichaelSHoffman 02:14, 16 August 2006 (UTC)
[edit] Moved list of amp makers
The list of amp manufacturers ought to be moved to another page. Where? MichaelSHoffman 21:28, 10 August 2006 (UTC) Done. List of guitar amp brands MichaelSHoffman 23:25, 10 August 2006 (UTC)
[edit] References
MIchael you've made some great edits, really, but sources still (or will) need to be cited. Please don't think that I think your edits are questionable though, because I think you've done some really accurate work. So I'm going to restore the section, but leave out the tag. maxcap 21:37, 16 August 2006 (UTC)
It is possible to cite one or more book pages for any statement in this article. I don't know which aspects of the article would make sense to provide references for. MichaelSHoffman 21:53, 16 August 2006 (UTC)

- I understand that, do you maybe have a first choice go-to book that you use? I'm not calling you out on it, and I don't think it needs to be done with any urgency. Just something to keep in mind. maxcap 22:11, 16 August 2006 (UTC)
Current most-useful books; preferable source for cites:
- Dave Hunter - The Guitar Amp Handbook
- Jon Chappell - The Recording Guitarist - practical amp usage tips per recording studios
- Aspen Pittman - The Tube Amp Book
I guess the important thing isn't which sentence in the article is supported by a given book, but rather, having a few good books present in the References section. http://www.amptone.com/booksgettingguitarsounds.htm http://www.amptone.com/booksamps.htm MichaelSHoffman 07:11, 18 August 2006 (UTC)
[edit] hybrid amps
A recent edit in Tube amp section (4 Sept 12.201.87.113)highlights a need for a short additional section on tube/silicon hybrids (Marshall valvestate etc). I'm not up to starting it but will be happy to contribute. 210.246.25.233 09:05, 8 September 2006 (UTC) Had an unsuccessful log-in, so signature for above comment should have read: RichardJ Christie 09:09, 8 September 2006 (UTC)
[edit] Possibly Biased towards Valve amps.
The section describing how a valve amp works tends to be biased in favour of them. There is little detail on Solid state amps, and they are compared "off the back" of valve amps.
- That's possibly because it is a section on how valve amps work ;-) RichardJ Christie 08:52, 17 November 2006 (UTC)
[edit] Clean/dirty
What do these things mean in a guitar amplifier context? Is it a specific reference to distortion, or does clean simply mean an absence of effects? Or is it something else altogether?

[edit] Nitpicks
There are modern tube amplifier companies that are designing fixed-biased amps that require no tube biasing so long as the proper rating tube is used.
properly rated tube?
New amplifiers with special processors and software can emulate the sound of a classic amps almost perfectly
classic amps.
Musicians often run sound-sources other than guitars through guitar amps.
sound sources.
Solid-state amplifiers still require power transformers
Don't some guitar amps have switching supplies?
Typically, a guitar amp's preamplifier section provides sufficient gain so that an instrument can be connected directly to its input, and sufficient power to connect loudspeakers directly to its output, both without requiring extra amplification.
Anything that drives speakers (rather than just a high impedance input) is an amp stage. IMO.
A 5-watt amplifier is perceived to be half as loud as a 50-watt amplifier
You might want to make it clear that this doesn't apply to amp/speaker combos.172.131.169.29 12:28, 7 March 2007 (UTC)
[edit] Analog Sensitivity; Device Failure
""Hard core" tube amp fans may not be able to tell the difference, in a blind auditory test, but will most always choose to play a tube amp because of its analog sensitivity."
Analog sensitivity is a meaningless phrase, and is not used in electronics. It should be deleted, or the sentence edited to say something like "Although they can't actually hear the difference, tube amp fans still prefer tube amps." (Well yes, that's why they're called tube amp fans. Duh!)
"When a tube fails, it is replaceable. While solid state devices are also replaceable, it's usually a much more involved process..."
But transistors don't fail! In a properly designed amplifier which doesn't overstress the devices, the lifetime of semiconductors is virtually unlimited. Tubes, on the other hand, have a very short life. The only reason they're easy to change is because they need to be changed on a regular basis!
As usual with discussions of guitar electronics, this article is not objective but is full of half-truths, unsubstantiated statements and personal opinions. Please try harder.
