Hey Jed, you started out a big advocate for MBritt and now Bert M seems to be more your preference (for live). Was it the BE pack that swayed you that way? I was using both of these legends for gigging (I have that illness where I use about 30 profiles live just coz you can with the Kemper ), but the difference in tones from these 2 probably drive the sound guy mad as I switch from song to song. I have found with Bert's BE pack that there is a weird transient (thats the best way I can describe it) in some of the profiles. I also found they hide in the mix a bit, so I have to tweak a little to push them forward (not too much). Not putting them down BTW, I too use both these guys probably 54% Britt to 45% Bert 1% a Friedman SS100 from RE that I added a cab to (but I think that one will go soon).
Ha! Yes Britt's profiles are awesome! They saved me on some occasions where I didn't have time to experiment much and loaded up performances without double checking at the right volume. I used them extensively/exclusively for a long time. However, one day I was on an important recording session and didn't get so lucky - I had stupidly forgotten my laptop and collection of profiles and was left only with those Britt saved in my Kemper which I insisted on using (because of the familiarity) instead of taking the amps they provided. I used them pretty much out of the box because I was a bit overwhelmed with the last minute call and the new client. Anyway, the engineer who had left the room wasn't impressed when he came back - it was an embarrassing failure but totally my fault and it still keeps me up at night. That incident was humbling and I had to rethink my approach and workflow with the profiler - I even went back regularly to a pedalboard + amps for a while in an attempt to "reset" my bad judgement! After that, the two following years have been slightly unusual work wise (let alone this pandemic thing) and I got into recording a lot more . I found I had to EQ and tweak some of my previous collection too often too much so my go-to's have started migrating towards profiles that I feel have more individuality (not one cab for all) and more variety in terms of range (profiles going from total clean to quite high gain.) I think Bert fitted the bill because he seems to be doing similar type of work (although in my case it's often all over the place stylistically.) I still highly respect both because they make profiles for themselves as performers first whereas I feel many others have jumped on this as a business opportunity or a hobby they can monetize and therefore might be doing this either for the wrong reasons or at least, not be doing it with the same things in mind. Anyone can put a 57 on an amp and make an amp bundle and a cool website but few have the knowledge coming from years in the trenches about what is likely to work best in a musical context. As a random example, take the Michael Wagener pack - who is quite honest about how guitar should sound in a mix - has been pretty much ignored/forgotten while others with better marketing or ratings on RM are sometimes drenched in reverb, full of ear candies and questionable frequencies.
About the BE pack, I love it but yes I also need to tweak it slightly especially for recording - I typically tame the low mids, bump the highs a bit or tweak the "high/low shift" slightly in the cab section a bit. Maybe I'm just used to them but they get where I want quicker than the others I came across.
