I have been on the fence about getting a good compressor for a while. I typically run my tube amps pretty saturated (6550 power section juiced), so things compress a bit naturally. Sometimes when I am tapping I wish I could take a dash of the edge off. I love the MPulse onboard compressor. I imagine it (and other onboard compressors) engages after the preamp and EQ stages. Wouldnt running a compressor in the FX loop have an essentially similar effect? I think that I want the compression added in at "the end". Interested in the MXR.
