Ah yeah, that might have been badly phrased. What I meant was, I want to avoid the thing where some pedals seem to get overloaded by low frequency content which makes low notes sound ragged or fart-y. Which can be cool in some contexts, it's just not what I'm looking for here.
For sure, and I'm definitely trying to keep that in mind along with the fact that I probably need a bit more midrange/less bass in a band mix than I like to hear playing on my own.
Did some testing at the practice, trying to get a handle on the low end thing. What I found was that with the Demon and especially the Drivemaster, I lost a noticeable band of low bass no matter how I set the pedal -- like there was an invisible "deep bass" knob on both pedals that was zeroed. It wasn't catastrophic, and the Demon especially sounded pretty decent if I didn't compare it to the clean signal.
But the weird thing was that I couldn't EQ that low end back in. I had the 40 and 100 sliders fairly high up and it still lacked low bass compared to [no pedal + no EQ]. I'm not a pedal builder, but it felt like there was some low frequency cut off point where the pedal had just stopped processing sound, so there was nothing there to boost back in afterwards. Does that even make sense?
