This question already has an answer here:
I have a Marshall JVM 410H.
I have the following pedals setup:
For the front of the amp I have:
Guitar > Compressor Sustainer > Chorus > AMP (input)
In the effects loop I have:
Isp decimator --> Harmonizer pedal --> Phaser --> DD3 Delay
The problem is that when I use the OD1 and OD2 channels and turn on the compressor a get a BIG hiss.
I have get rid of the noise if I set the ISP decimator (noise gate) higher, but the playing get's cut off.
What I'm I doing wrong? Do I need to use 2 Noise gates?
