Hi Jazzy,
Redwood is a softwood, but so is the maple from the western US (where quilting and wide flame is most common). I haven't played an Alembic with any maple but I do own a couple of Rickenbackers and early G&Ls that are primarily maple. They are all on the lightweight end of the spectrum. Is the maple in your Series bass flamed, quilted or birds eye?
Side mounting the 1/4" jack was my first choice for exactly those reasons, but it would have added some weight due to (a) needing a thicker body, and (b) the the jack itself being a different part that is significantly heavier.
With the Signature electronics, five-pin jack and a three-way LED switch, the controls are going to resemble a Series I layout but without the hum canceller. Space might get tight on the small body, so Mica is going to run the layout by me before any drilling starts.
Speaking of the body, I meant to post this picture a couple of messages back. It's a comparison Mica drew overlaying the Essence, Spoiler and 3/4 Spoiler body templates. Just in case it's helpful to anybody else's custom ideas...
