    Im using this with a QSC power amp and a GS410. Im really happy with the sound so far - incredibly clear and lots of thump. However, im having a bit of trouble getting the EQ right. Ive read about parametric EQ but cant quite get it right. Last nights gig bought lots of compliments about the bass sound, but our drummer said he had difficulty hearing the lower notes from my bass - 4 string P.
    Any advice/tips appreciated.

    The full parametric dual band mid can be a little overwhelming if you are not used to it.

    The main difference between these mid controls and the typical semi-parametric mid controls on most amps and pre's is the Q control... the bandwidth that allows you to widen or narrow the range of frequencies around the center point you are cutting or boosting.

    One way many approach the bandwidth control on a full parametric is to use a relatively wide Q when boosting, and a tighter Q when cutting. A tighter Q lets you zero in on specific problem areas to cut, and a wider Q allows you to provide a subtle, even and musical boost where needed.

    If you feel your tone is too mid-mid oriented (i.e., honky sounding), try a medium to slightly tight Q cut at around 500 or 600 hz). If you are hearing some upper mid 'gank' to your tone... some unpleasant harshness in the upper mids, try a relatively tight Q cut around 1.5K or 2K.

    If your tone is too scooped, make sure not to turn up the shelving bass control too much, and try a wide Q boost around 400 hz or so.

    If you feel you need more low mid punch and 'bark' to your tone, try a medium Q boost around 150 hz or so.

    These are just very general ideas, and the exact settings will vary given the voicing of your bass and cab, and of course, the room acoustics.

    However, there do seem to be some general 'magic' points in midrange EQing, around 150 in the low mids, 400-600 in the mid mids, and 1.5 to 2K in the upper mids that are good starting points for boosting or cutting depending on the issue.

    Just IME and IMO with the above. That's a beautiful preamp, but it can be a little fussy for live performance.

    You might also want to PM TBer Chef if he doesn't show up here... he uses one and is a parametric EQ fan!

    Edit: Also, as with any tube pre, there's a lot of sound in the level of the pre gain control, so try different gain settings.

    I used the amp and cab for many gigs. since you are having problems being heard in the low frequencies. I would check the bass boost/deep switch. With the pbass this switch sounds good up close but can make the low notes almost dissappear in the mix.
