Dear Sy,

If you call an amplifier with such measured results an "effects box" you must have reliable and incontrovertible evidence that such levels of (for example) distortion or frequency response deviations will be reliably audible (using appropriate speakers) and will produce a reaction by some that is positive and makes the prefer this "effect sound".

Please present this evidence so we all can gain this knowledge, as so far I am unaware of any such and would be rather keen to remedy this lack of knowledge.

Irony, not sarcasm. Though the former is frequently mistaken for the latter by people in one of the former british colonies.

As for the graphs. They tell us something.

They tell us for example that the frequency response is reasonable for a transformer coupled tube circuit without feedback, that there are no major resonances (only well damped minor ones) and that the distortion is of a very simple, low order dominant type.

In other words they tell us something about how well certain engineering goals have been met.

If we look at other graphs we can see that distortion does vary only minimally with frequency.

How you view this depends entirely on your frame of reference.

In my frame of reference I see little to worry me, as my frame of reference is based on evidence of audibility or not of distortion, frequency response variation etc. that are known.

People with other frames of reference (e.g. not evidence based - but faith based - believing that somehow better abstract numbers mean better sound) are likely to loose their breakfast and proclaim the results as unacceptable.

Whadya expect? It takes a good 5,000 posts to "break in" a thread.

This filter is usually placed ahead of the Amplifier, don't make it and the tweeter to do things don't want it to do anyway...

Given that much of the discourse is strictly faith based and makes zero references to any evidence based principles that should not unduly worry you.

Believers will always believe what they will and get into a fight over it.

Some believe in numbers, others in what they hear. Both have a point but each views their position as completely irreconcilable with the opposite ones, failing to see that the two positions complement each other and are more like the two sides of a coin or the two opposites represented in the classic Taijitu symbol.

Few ever get to the point where they can combine both sides and see them as one.

That's the first "single ended" amp I've seen with substantial crossover distortion!

What do you call this one?

Ultra Shockwave?

Mega Crusher?

Hyper Metal Screamer?

Massive Mega Muff Fuzz Face?
