That is the same build recipe of my first Alembic. You have some good times ahead my friend...... I can tell you from my own experience with it that however great you think that bass sounds now, just wait till you become au fait with the way the controls work and you can get to the sound you "want" rather than the sound you "find" and that's when the real sonic overdose kicks in!!
Keep us updated on how you feel after your first gig.
Congratulations and welcome to the club
