I have 3 big body, magnetic p'up guitars I gig with. This little blue box certainly "brings out" very happy nuances from them all, for me, a new and sweet sound, not loud or aggressive, but happy. Mainly, this blue box is a preamp/di, needed for the "sound guys hereabouts".
I live in France, doing many genre of music. With a French lady singer, classic French music, I do solo anglaise pop, rock, etc. I gig with an English r&r band, sometimes only for free beer & a feed when finished, sometimes for good €.
I use this blue box on batteries, as quick setup/tare down are important for mid evening changeover, a big thing here in France.
quilter is a new name to me, but am glad I got this thing, no massive big changes in my big aulde guitar sounds, but it certainly is bringing out the sweet nuances of "clean sweetness" for me. Beware the "gain" beyond 7/8ths, it's probably where r&r begins. 7
