Hi team- I was tracking a guitar part last night and came across incredible noise when using Logic's guitar amp plugin. I was using one of the higher distortion settings, I believe it was the 1959 marshall, but the amount of noise (like white noise, similar to sound of a cranked guitar amp) was greater than the sound of the guitar when I was playing. I tried using a noise gate, but had to crank it up so high to get it to work that it is cutting out some of the guitar too. Any idea what's wrong here? I checked audio cables, its not that- I get the tremendous white noise even when there is no cable connected to my audio interface (RME Fireface). Logic 7.2.2, MacPro 2.66 w/ 2 GB Ram thanks doug

Most of the models will do that and get nasty if you crank the gain or volume high enough.. For the kinds of guitar tones I like, Guitar Amp is pretty useless because of this.. I just use my Marshall JCM800 which sadly is worlds quieter hum-wise than Guitar Amp is.. But than again, I assume sitting in front of a CRT monitor, alongside my speaker monitors doesnt help. But even plugged into my real amp, sitting in the exact same spot at my desk, the noise doesnt get half as bad as is does with the plugin.. -- Chris http://www.monotrematamusic.com http://www.myspace.com/monotremata http://www.descentrecords.com

I don't understand why shortcomings of hardware must be emulated in such a demonstrative way. The noise should be an adjustable parameter in my opinion. The Guitar Amp Pro is basically a good plugin and works well with a very clean signal from the guitar and preamp. Very clean. Cleaner than necessary for an analog preamp/amplifier chain. Maybe some istruments and effect boxes just have the "wrong" noise for the analog/digital migration. My several instruments work totally different. Some hiss like hell (is there hiss in the hell?) and some work acceptable. That is not only true for Logic but also for other software. I began to hear the real sound of a Rocktron bass preamp (hardware, digital) after adding a line conditioner to the setup. And the really real sound with another bass. Maybe the software picks out a certain type of noise. Although I find the Guitar Amp's noise generally too loud, in many cases there might meet three incompatible parties: a guitar with the "wrong noise", an overdone simulation and a common problem with amplifying noises somewhere on the way between instrument and software. The latter is a theory but I have no better explanation yet. ___ Peter Ostry

The noise should be an adjustable parameter in my opinion. I don't think the noise is added separately. If you simulate the inaccuracy of the hardware (for the effects it has on the sound), the noise is a result. But yes if it is that much louder than in the original amps then something is wrong with the simulation. :o) However, couldn't there be a signal problem between the guitar and the audio interface? Guitar signals are very prone to ground problems etc, and they can vary very much depending on the equipment they are plugged in to. And surely GPA doesn't simulate ground hum, that's really just in your signal and then being amplified according to your gain settings. > different. Some hiss like hell (is there hiss in the hell?)

The latter is a theory but I have no better explanation yet. That theory isn't all too far-fetched, seeing how much difference in noise you get by plugging your guitar in different amplifiers. :o) Maurits.

I have been complaining about that since day one. It is noisier by far than a decent analog guitar amp and it also seems to have some kind of compression going on before the signal even hits the "virtual" tube that makes high gain tones seem kind of mushy and unsatisfying. OTOH I like the speaker simulation in GAP. IMO it is the best among the guitar amp simulator plugins out there.
