The JVM is still tickling him and keeping him cool. Plus Liverpool got through to the semi finals of the Champions League to face Chelsea, with the second leg at Anfield. All in all a smiley face.

Mike in a good mood, or just short on time?

I'm a busy man, work is insane and I have no time to engage in a debate about my knowledge level with some no-mark who gave shit advice in the first place. I mean - we all have heard of volume pedals right?

Ah. I see I said volume pot when I meant drive pot. Typo. Shouldn't have been that hard to figure out what I meant.

You connect the DRIVE pot on the pedal to the wah pot. Thereby it controls DRIVE.

What is the difference between Gain and Volume?

Volume controls the overall loudness. Gain controls the prominence of more specific sonic properties, but I don't quite know how to explain that.

Gain (DRIVE) controls how hard you "push" the amplifying section of the pedal. "Gain" is an attribute of an amplifier, and dictates how much larger the waveform is increased. Push it beyond the limit of the supply, or past the clipping threshold of the diodes, and you get "distorted" which is the point of the gain control in an OD.

However, I was mostly just looking for a response from exo, to gauge his level of knowledge in electronics.

You're expecting some kind of... leeway there aren't you?

Yet you're the one who replied with "you don't know much about electronics do you?"

Dichotomy.

Oh, oh, I might know this one professor.

Volume is a sonic variable, gain is an electronic variable. Gain is the amount of voltage in a signal, which will usually relate almost directly to volume, but, due to the signal-distortion experienced in various audio equipment at high gain levels, the term is usually used to mean "dirtiness."

Did I do well? Seriously, is that about right, or am I totally off?

Did you miss the above posts, Paul? It wasn't a general question, but aimed at Exothermia.

Yeah, but it had already been answered by others, so I thought I'd give it a go.

But for completeness' sake - this is not correct.

Gain refers to an amplifier stage, it is the ratio between the output and input signal, the Gain is the factor by which the input signal is increased (or decreased if Gain is <1) at the output. You can talk in terms of voltage or power gain. Distortion is achieved when the gain is sufficent to distort the waveform by clipping or gentle compressing (transistor vs. valve) of the waveform as you approach the maximum and minimum swing voltages.

So, gain is sort of the amount by which a circuit increases or decreases voltage, or amplitude in real (non-digital) terms?

Gain exists in a digital system also, just by completely different means.

This is a simplistic, if not entirely gospel view:

Volume=loud
Gain=RAWK

all one needs to know

I wonder where Exothermia went?
