Very short signal chain. I simply plugged the guitar straight into the input of a Firewire 410 which claims to be compensated for pickup input. Didn't care about frequency correction but got a good levelled clean signal and far less noise in Guitar Amp Pro. > I've tried using a H&K Red box, either through a Mackie board's mic > pres, and also straight in balanced to my MOTU 2048 mkII, but that > didn't really help with the noise problem. I tried a rather good compressor as a frontend (Fat Man) but it is also unusable because of noise. The Firewire 410 alone works. I am surprised that going straight into the MOTU gives you much noise because interfaces alone usually add very little or no noise. Did you add much gain or do you have an active pickup on the guitar? > I'm guessing, as with real amps, a noise gate might be the answer, but > I haven't found settings for Logic's noise suppressor that are > satisfactory. No, this plugin can't do the job. And it looks like GAP sees any sound as very important. Unfortunately this is not right behavior - there are problems in the usual guitar/amp chain we do not like in reality (i.e. noise). They have to be suppressed but not taken as part of the model...
