Aion Perelandra Deluxe (Xotic BB Preamp Mid Boost)

Yesterday I completed the Aion Perelandra Deluxe, which is an amalgamation of the various Xotic BB Preamp versions that have been released over the years. In particular, it adds an active mid boost control, as well as three clipping options. Very similar to the PedalPCB XB-MB Preamp, but that doesn't have clipping options. (Although, with a little ingenuity, you can easily add the clipping options, as MichaelW demonstrated.)

Pretty straightforward build. I've actually had this PCB since June, just never prioritized building it. One thing that jumped out at me, that I appreciate, is that the overwhelming majority of components are very common values (e.g. most resistors a multiple of 1 or 4.7). So I had all the parts on hand (including the dual-gang pot), except the B1M drive pot. I used an A1M instead. Same max value, different taper. With what little I've played with it so far, I do kind of wish I'd held out for the right pot. That said, I haven't decided if it will be a permanent fixture for me or not. If I decide it will be, then I'll probably make my own PCB with integrated relay bypass and maybe a voltage boost or something.

As for the tone: I think the active mid boost control is the killer feature here. Somewhere I read that with the mid boost at 9:00, it's roughly equivalent to the more common version without the mid boost. To my ears, even with the mid boost all the way down, there is still a bit of a mid-hump. My understanding is that the BB Preamp is basically a tube screamer with the tone control hardwired to minimum (or near min), and then the active Bandaxall tone stack grafted to the end. Personally, I'd like to see something a bit more transparent with all controls at noon. That, combined with the clipping options (especially the no-clipping) would make it really flexible all-in-one kind of pedal, serving as a boost, overdrive, and EQ.

As for the clipping options ("comp"), I found myself gravitating to the no-clipping setting, which is essentially opamp overdrive. I expected that to be harsh and unusable, but I actually like it. It does have the "splatty" decay noise, but I find that charming.

I think my build looks decent. I used stereo I/O jacks because that's what I had on hand. I put a skull on it because I couldn't think of anything else. I did use the comic sans font as a nod to the Xotic pedals.

I've owned the retail BBPre a few times over the years. I think the Perelandra sounds better than the retail versions. Dunno if it's the Custom Shop features or what. I gave mine to my brother since the XB-MB was the one I hacked that you referred to and I didn't want that crapping out on him mid gig...... :ROFLMAO:.

I mentioned in another thread, the BB is kind of like a Swiss army knife drive for me. It can do the TS thing, it can get "somewhat" transparent-is with the mid control turned down. It can get very saturated in the Andy or Comp modes.
I tend to like mine in the Comp setting the best with the gain turned down.

Great looking build man!
 
Does anyone have what parts to change to make the Perelandra Deluxe a bass version?
It's all available at Aion, IIRC.

Go to the link above, scroll down to the BASS BB schematic as above and click on it and you'll have the Hi-Res version of the schematic.

In my notes for AION Perelandra V1 (V2 available now) [Xotic BB Pre&Bass], I would ...
ADD CLIPPING SWITCH for options;​
SUB R19&R20 for DLX’s W20K MID;​
SOCKET C17 220n~1µ;​
SOCKET C6 & C8 and START AT 10n each.​
 
i built the Bass BB version on AION's Perelandra (twice!) and compared them to my original Xotic Bass BB and it doesn't really sound as good or really anything like it. it doesn't have anywhere near as much gain (distortion) and it's a lot brighter sounding. on the original with the treble and bass at noon it's basically flat, whereas on the Perelandra the treble has to be a max counterclockwise and the bass boosted.

While the Perelandra can be set to sound pretty good, it's nowhere near as good as the original.
 
Maybe the local chef, @Robert, needs to whip up a version of this recipe.


I'm always amazed at how different things can sound, even when it's the exact same circuit (Rats in particular); the same way two restaurants cannot produce the same quality of ... chicken parmigiana, or whatever... hell, even the SAME restaurant and chef can be inconsistent.
