London, goin to Western at the moment.
For your woods, swamp ash is a tad brighter than alder, think fender strat sound. Ebony is super effin bright, even brighter sounding than maple, my favorite fingerboard wood cuz its smooth and cuts out the mud. Rosewood is nice and warm which should get your mids and low mids.
The wood of your guitar is going to focus your tone towards mids and highs, so a warpig will be a nice compliment so you can get some bassy tones out of it.
I'm not quite familiar with your Laney, but if it sounds anything like a marshall, you will want heavy ass low end, strong mids, and trebel clear enough that it balances out the tone. Since your guitar will already have the mids and trebel in the wood, warpig should do it.
