TC BAM200 - Flat response settings

[Alex Kenivel]

There has been some discussion online about how to make the TC BAM200 bass amp work as a solid-state power amp for guitar cabs, including settings to make it so.

Since I've had it, I've been a little skeptical about the currently posted online opinions on how to manipulate the knobs for a flat response so I decided to dig a little deeper.

I ran pink noise into the BAM, tapped the speaker output and ran it into FabFilter Pro Q3 to see what's going on with the frequency response and this is what I've come up with:

and the settings used:

Compare the frequency response when using the older posted settings (B:10/M:3:30/T:10):

That is all. Thank you for listening to my NerdTalk.

I would like to mention that ears are King. Although this gives me a very ruler flat response on the Spectrum analyzer, I found that lowering the bass to around 2:00 makes things more pleasant in the room.

Those are some interesting settings to get things flat on a bass amp...seems like you're bumping UP the bass.

Have you tried something like the Seymour Duncan Power Stage units? They're pretty flat out the box with everything at noon.

Yes, I turned up the bass knob so the low end starts sloping off at 100hz instead of 400hz.

Honestly, in practice, I kind of like the bass dialed back to non-flat! Flat doesn't always equal pleasing!
Now that I've had some uninterrupted time going back and forth between Amp and Amp Capture, I've moved the bass knob back to 10:30 to make them sound alike

Maybe I'm doing something wrong? idk..

I have not! I probably should, though!

But the Seymour Duncan stuff > 2x the price. I'll just turn the knobs.

How did you tap the speaker output? Did you use a DI box in between the speaker output and your cab? I was thinking about adjusting my PS170’s EQ in a similar way to get a flatter response.
