I've read elsewhere on here that "pure boost" - used in a stomp slot - does the same as adjusting the Amp section's gain knob: Pure booster and gain relationship - though some people on the thread disagree (and I'd tend to agree with them!)
While I understand they may both be technically simply applying gain, I feel that they serve quite different functions (presumably because of where they are placed in the virtual signal chain?)
I find if you sweep the dial on the pure booster, there's always a "sweet spot" where the profile just feels the most alive under the fingers - any less than this and no matter how much you dig in with the pick it doesn't quite feel like you're getting enough bite - any more, and it starts to feel compressed, loses dynamic range. Increasing (or decreasing) the Amp section's gain knob just doesn't achieve the same thing - you obviously get more (or less) distortion, but the feel/response can still be improved using pure boost - in fact, once I've found the "sweet spot" on the pure boost for a particular profile, I find this value works no matter how much I increase or reduce the Amp gain. btw, this "sweet spot" on the pure boost need not necessarily be a positive value - e.g. in the thread linked to above, Rescator says he tends to use negative values to compensate for his powerful pickups - I generally end up with positive values however, presumably because my pickups have less output than his.
Anyone else use pure boost in this way - i.e. not just to boost gain for solos, but to idealise the general response/feel of a profile?
I guess how I'd describe it is that - similar to how Definition and EQ can be used to optimise the tone of a profile to suit your pickup's tonal range - the pure booster can be used to adjust your pickups output to optimise the response/feel, which does seem to vary from profile to profile.
(And as I know someone's bound to ask, yes I'm aware of and have adjusted clean and dist sens in the input settings - I have these set to my liking per guitar, and review them regularly, though always return to the same values, so am assuming I've got them set "correctly" - anyway, adjusting these parameters does not achieve the same thing as what I'm describing here re. the pure boost.)
