Gain on my F1 is set at about 25% as my Sadowsky clips like hell any higher.
Wow.. you must either have a very strong 'touch', or you have the bass control set way too high on the Sadowsky. The clip light does not come on on my LMII or SD800 with my Sadowsky when slapping the B string HARD until the gain is set at about 2 o'clock, with both pickups on full (i.e., blend centered) and the on-board bass boosted the 'typical' 10% of so to fatten the tone up a touch.
However, I have a relatively soft touch, and my 'slapping hard' might not really be that hard!
Edit: Just saw your Sadowsky thread. Beautiful bass. I wonder if the older one's have a hotter output than the current models? Mine is relatively new (about 3 years old).
