I thought of simplifying my bass guitar stage rig by consolidating two of my fave boards (as above) into one housing for ease of use and to minimise onstage clutter.

Together they are just too wide to fit into a 1590BB, so I chose a 1590J enclosure to leave some wiggle room in case. I took a day over each board and still managed to bork the first Lumin* build by carelessly fitting two temporary DPDTs (ordered from my local in good faith without due care in checking their configs). This error made the first Lumin unusable for my purposes because I find the switchable frequency its most useful feature for fine-tuning bass response in different live settings.

Thankfully I had a spare and built the replacement board quickly. Here's the finished article.

Does exactly what I want from a tone-finessing PoV.

For bass guitar, I'm using Kevin's Acoustic 360 bass preamp as a front end and finding some joy in its tweakability. The Tso adds phat as necessary, with the Lumin at the end enabling fine tuning to go from a Jaco-ish bridge pup toppy sound to a gutsy Billy Cox type neck pup sound (more vintage Fender bass-like).

For guitar, I'm going to swap the 360 for the IVP as front end. It's over-glassy for my taste and the IVP has more precise control over midrange, its tone controls being active AFAIK. Thanks for reading as ever and wishing you all rewarding and fruitful builds.

Thanks! Feel free to…

FWIW I originally thought of a small order switcher board but didn’t follow through given the tight space available.
Brand new builder so I will need some more practice before I attempt it but have the pcb's in my respective wish list for my next big order.

Go for it. The individual boards by themselves are reasonably easy to assemble. The tricky part is finding a suitably wide enclosure to fit them in. Feel free to get in touch if I can help when you’re ready to go ahead.

Appreciate it!
 
PHAT-tastic!

Good to see one of the lesser-utilised Hammonds employed here.
The J and the Q are underdogs in the 1590 series, IMO, not sure why they both aren't more popular.

Nonetheless, if you're ever building another you might consider the Aion Legacy Lumin, which fits a 1590B;
so combined with the N1-sized General Tso, they might just fit a 1590BB.

I just checked the PPCB BBW, and it's only 50mm, Tso is 58mm — internal 1590BB width is 115mm, so it'll just fit.
 
Thanks for the kind words, Feral.

Close inspection of the existing gutshot shows how narrowly I averted a complete disaster by not checking the enclosure's internal dimensions. There's a bulkhead-type thingie where the screws mount which almost borked the entire build.

The Tso just fits; close enough for jazz, as they say.
