If you're on the fence about a HPF/LPF, please check out my TB Wiki on the topic:
High Pass and Low Pass Filters and/or read through the
High Pass Filter (HPF) and Low Pass Filter (LPF) Mega Thread to check out how other TBrs are faring with theirs.
For my TB brethren who don't want anything on the ground between them and their amp: the Broughton Always-On HPF does not have a footswitch and is so tiny and light weight you can set it next to or on top of your amp(or hang it from), use 1-2ft patch cord into it from the amp, and run your bass cord from it through the handle(so you won't pull the HPF off of you amp) into your bass. Ez,Pz!
Dial it in based on the FOH mix, not what you hear on stage.
Oh, and PLEASE, put your amp on a stand or use a wedge (like the adjustable [Invalid or Expired Link Removed]) to disconnect from the stage and more importantly, to get the sound away from your knees and closer to your ears. Btw, the On-Stage wedge folds flat for transporting.
IMO/IME, based using my Bro-ton Always On, best piece of kit I've added to my rig. Wouldn't leave home without it! The other bass life changing happenstance was to switch to an active 3-band eq '83 Ibanez Musician PJ. Along with the HPF, I can beat any rig/venue into submission.

HPF/LPF list- which do you use or know about?
The tone that makes your group sound good in the FOH mix is the only tone that matters.
DO try this at home!
