External EQ

I'm toying with the idea of getting something like a Boss GE-7 eq to run in the loop of my GM40 to give me some more flexibility in fine-tuning my tone. So, I'm wondering if anyone else has done this, how it worked out, and if anyone who has done it has any tips for how to set it.

Thanks!

I've messed around with using EQ pedals before, and I usually ended up ditching them because they screwed with the natural sound of the amp and made it sound weird.

The exception is if your amp/rig is genuinely missing something EQ-wise. I used to use a combination of gear (Les Paul, Blackstar pedal, Marshall cabinet) that was very dark sounding, so I used an always-on parametric EQ to boost the mids. Cheap chinese pedal that I got for £30, but it made all the difference in my guitar actually being audible in a band mix.

As guitarists we're never happy and always want to tweak more. But personally I think the GM40 has a great natural sound so I feel no need to EQ it further, but it will all depend on your cabinet, room etc.
