Hey fellas, I've lately been considering adding another EQ to my board, specifically to run in front of my 5153. I currently run an MXR 10-band in the loop, which awesome. I actually have two MXR 10-bands, but one of them has a problem resulting in random pops and static, so I don't use it. What's really driving this is that I've tried it before and was able to get some really awesome tones. Specifically, my 5153's red channel, which is the main channel I use for gain on that amp, doesn't necessarily need an OD boost. Whatever they did in the filtering in that circuit, it is very tight and saturated and almost feels like it's already boosted. I can get good tones with my OD if I turn the gain way down, but ultimately there's a thickness there that gets cut no matter how I adjust my OD (MXR CMBA OD). I was thinking another EQ set to boost/cut certain frequencies would help me retain what I like, without sacrificing that natural sound. If you could tell me the pros/cons of each pedal, that would be awesome. As stated, I'm experienced with the MXR 10-band, but not the 6. The 6 has different frequency ranges that match those of the Boss unit, however, that doesn't necessarily mean they have the same bandwidth on each slider, or "Q" factor. I owned a GE-7 eons ago, but I was a drunk college student at the time and used to play full sets with a wah cocked all the way forward -- in other words, I had no clue.
