I have the trio. spent some time with the Biscuit in the past and it struck me as wonderful with percussion and less wonderful on melodic sounds, which didn’t fit what I was looking for.
I think I already extolled its virtues to you on Instagram, but I love the Boum. I think it does quite well as a dirt box and manages to live up to the playability of the other boxes while still being a useful compressor. honestly, the simplified single-knob compression setting is about as advanced as I want to get most of the time. haven’t used it with the sidechain input yet. I know some people love more precise stereo compressors like the bugbrand one, but I think Boum strikes a nice balance.
the hi-cut filter is lovely, the gate function can be really nice (especially if you have your Boum after your reverb, so it starts breaking up the fading reverb tail), and overall it lives up to the other two boxes in quality and sound.
