Yep, I added the (optional) UltraBASS control:

I'm assuming the midrange switch is
probably similar to the Flat / Sub / 600Hz Boost switch in the Designer / Drebbel.
Yes,
according to some old research on TalkBass I'd completely forgotten about, at least one version of the Submarine had a toggle that matched the later Submarine Designer's ULTRABASS.
BTB, the links in above TB link are link-incontinentals, ie Os' Ziebek site is no longer online ie dead, but anyone wanting Submarine Designer manuals can still DL them online elsewhere.
It's been weird combing through old TB threads looking for info on the Sub-Designer/Ictineo — so much info I'm rediscovering even though I once knew...
Sorry, what were we talking about?
Right! So the Ultrabass control is NOT a tone-stack modifier that gets you bumped, flat, scooped mids. It does something else to change the EQ point, I think. If you look at the Submarine Designer, ULTRABASS is not part of the Modifier switches, which given the Freqs would be responsible for modifying the tone stack itself.
So, when all the switches are set to "SUB" and the body control is at the asterisk, "
*", the SubDesigner/Ictineo replicate the original ElectroniX/Zeibek Submarine — according to the SubD manual.
Some other interesting titbits I came across: the original-original Submarine was issued in a plastic enclosure and was recalled by Os — this earliest version didn't have enough headroom and would distort in a bad way when driven hard.
So, do I wait for the Sub to surface in the shop and add it to my Drebbel build?
Surely two subs are better than one.
