Fender Bassman 250/210: Excessive Clipping?

[rapturebass]

Firstly, thanks to anyone whos stopped by this thread, and for the help you may provide. I recently joined a band where we play relatively loud, at an almost daily level. I noticed that recently my amp, a Fender Bassman 250/210 i bought used off Ebay roughly 2 years ago, has been clipping more frequently than I wished, both in the preamp and occasionally in the power amp. Granted, its not clipping at every note but its rather bothersome how this has continued to happen. I've tried adjusting both the Channel and Master Volumes on the amp, as well as the volume on my Boss ME-50B. I usually keep both volumes on the amp at 12'o clock, but no matter what position it's prone to clipping, it would seem. Everytime i pluck/pick with some extra force (i get into my playing pretty easily; so I'm prone to "digging in") the preamp clips, with heavier plucks/picks clipping the power amp, with the low E being the most sensitive; digging in just a little bit causes the amp to clip. Does anyone have any suggestions as to how to cure this? There seems to be little insight on this, thanks to anyone who can help me with my problem.

I use:
Pick/plectrum for most songs, fingers for ballads
Fender Marcus Miller Jazz (usually passive, active for ballads)
Fender Bassman 250/210
Boss ME-50B
Monster S-100 Instrument Cable
Monster Bass Cable

^In case any of that information is of use. Again, thank you for any insight you may be able to offer.

I owned the 115 version of that amp and never had any issues, but my first suggestion would be to check and make sure your bass's preamp isn't fully cranked when in active mode. Other than that, check the ME-50B and make sure the master volume isn't set too high (I have a GT-10B and always keep the master dead centre), check the effects you're using and make sure their volume levels aren't too high, and check the active eq on the amp itself and make sure you don't have it turned up too high.
