If thats the case, I will definitely look forward to trying out the F1. If I have one complaint about the Little Mark is that the low mids were somewhat lacking. I noticed this especially when playing my fretless and comparing it to my Thunderfunk.
I hadn't noticed that... in fact mine sounds great with my fretlesses and the low (and high) mids are a big part of why I like it. I'm still setting my EQ on the MB flat just as I did woth my Thunderfunk and if anything just dial in a little bass on the bass itself.
I wonder if you can really tell much of anything at NAMM re: one amp vs. another? You're limited by the speakers on hand and volume... at least that's how it's been when I've gone.
