You say with the passive D/I Box
a) "I am able to set adequate gain levels." What concrete gain levels on which analog input (1, 2, 3, 4)?
b) It "sounds conventional" with "limited headroom".
What is the limitation? Please detail the metering; what average and peak levels do you see?
That you can set an adequate gain level and be limited with headroom sounds like a contradiction.
You have to deliver more details; see a) and b) to better explain what you mean, and to get a clue about what the problem is.
What passive D/I box do you use?
Please note three important points:
1. You should better use an active D/I box because a passive one will most likely impact higher frequencies of the signal

2. You need to connect the D/I Box to either Analog 1 or 2 IN, NOT (!!) 3+4, as 3+4 are limited to a max input level of +13 dBu at gain 0
3. You need to activate PAD on Analog 1 or 2 IN; otherwise, you won't get the max input level of +19 dBu!!!
I’m using a cheap passive DI on input 1, I tried both with the pad on and off, no clipping on either setting, so I kept going with the pad off, and I rose the gain 35db without clipping.
Then I got back to try the BFP Hi-z, and no headroom, but it didn’t clip, it might be because I was playing fingerstyle, or using less strength plucking. I don’t think the DI could have any interference on this scenario.
This morning I went back at it, the pad seems to muffle the sound, I´m not quite sure if it just lowers it, but it feels like a slight roll off on the guitar volume, taking out the poisonous frequencies that might set back rhythm playing to a uncontrollable mess, but sometimes I like it fully open.Frankly, most of the times, as I might dial down the gain on the software I´m using. The hi-z input returned to its behavior, it shows clipping every time i hit the strings harder, and on the lower strings most of the time, both on +4dbu, or -10dbv. They sound both quite well, but clipping shows its ugly face. nevertheless, rarely the green goes past 22db, but then the red starts to warn me about clipping.
I wonder, am I right, are the meters right? but that shouldn´t be an issue, when I purchased the BFP, I thought I was buying into no problem, straightforward flexible setup. Until now, that´s not the case.
I heard the Hi-z input lack of headroom was by request of the forum members, and done with a firmware update. It doesn´t seem they thought it well enough.
Thanks for your concern and advice.
