Does the Mesa Big Block 750 have built in HPF?

That’s a PA amp - not a bass amp. It’s not what we were talking about here. Bass amps (save the one I’m talking about) have high pass filters.

Plenty of people used DC300s for bass.

Still not what we’re talking about. PA amplifiers aren’t designed to do the processing necessary for use as an instrument amplifier - they’re a power amplifier, the user is expected to know how to feed it an appropriate signal. To use a DC 300 with bass, you’d need a bass preamp, and a well designed bass preamp woul have a high pass filter. The fact that you aren’t aware of the one bass amp line that briefly featured DC coupling helps make the point that bass guitar amps come with high pass filters.

If you want to stay 100% on topic, perhaps you should restrict your comments to the BB750 and HPF.

I was addressing someone who said that particular amp didn’t have a high pass filter because… Ok, he didn’t have a logical reason. My input was that All intelligently designed bass amps have them. Right on topic, until the Crown diversion.

2. The later SWR products, such as the Spellbinder Blue, HeadLite and Working Pro, did include HPF's, this is a natural evolution. The same applies to the later speakers, they became more robust out of necessity as the costs of warranty replacements became unacceptably high.

3. The entire Eden WT series included a HPF, as did the WTX series. The low frequency band is not fixed at 30Hz, but sweeps from 30Hz to 300Hz, but with the included HPF, this effectively shifts the 30Hz calculated point upwards somewhat.

4. The SVT-III (and SVT-III Pro) does have significant first order HPF, not as aggressive as many of their later products like the PB series, PF series and SVT-7 Pro. Again, designs evolve.

Thank you

First of all - thank you for your knowledge and your willingness to share it with us.
And what is maybe even more important - thank you for your patience for people like me

Since HPF is a pretty new silly fad and Big Block is a pretty old school hefty amp - i'd say no. And in my opinion you don't need HPF - build in or in a pedal - for this, or any other head.

I never used one until i blew some speakers twice playing upright. I actually cannot hear the difference but eliminating the ultra low frequencies from the E string my speaker excursion is greatly reduced. Many years ago many upright players took the E string off or left it slack because it was basically inaudible also for years uprights were often built with 3 strings in this context it may help explain an HPF
