Hello Thomas, and welcome to the club. I must say you didn't go wrong by selecting the MK signature bass as your first Alembic. I owned a SC signature-4, which I later swapped for a MK signature-5 and I loved them both. I had to part with the MK seven months ago, when my dream came true. I was blessed with my series II and I AM PLEASED! Trust me when I say that the sorrow I felt by separating from each bass soon passed after bonding with the NEW addition, LOL. I used to have difficulty as well, trying to establish my sound with the filter controls at first, I guess it's normal, LOL. Anyhow, I started by panning from the neck PU to the bridge PU and listening to the differences in the tone, then I did the same for the filters. The filter knob(BELOW Q switch)near neck:neck PU filter, filter knob(BELOW Q switch)near bridge: bridge PU filter. There are(2)TWO position filter Q switches, one for each filter. When the Q switch is in the upward position it cuts, however, in the downward position it boosts. The beauty of this is that you have MANY possibilities...Don't be afraid, because in order to find/hear YOUR sound, trial and error will be a one of your best guides. Also, search the club archives, I remember reading a post authored by MICA and she explained the controls in detail. Welcome to the KINGDOM OF TONE!!!
