Typically, a scale of say +/- 20dB relative to a nominal zero (whatever the baseline datum ends up) gives a pretty good indication of the relative solpes to the overall response. If you get much finer than this you risk not being able to see the forest for the trees. The other thing that's just as important is whenever comparing graphs between different models or manufacturers, you MUST use the same scale or the comparison will be distorted.

While I absolutely agree with the language in bold, I think that +/- 20 dB is a bit on the overly broad side (for an amp, at least - it might be more appropriate for a cab), and may not illuminate peaks or valleys which may very well be audible in a live situation.

As another FWIW checkpoint, we also used +/- 5 dB in our response curve for the SVT.

Well, I have the new graphs done, with about a +/- 11db scale. I also figured out how to remove the scaling differences between curves so that the measurements are more inline. I think any inaccuracies in the graphs here (of which I'm 100% sure there are some) just exist because I don't have the proper equipment or know-how to do it any better. But honestly, my point in this really wasn't to get a perfect picture. I was hoping just to show something that gave a basic representation of the EQ profile, and how twisting the knobs brings an effect.

Thanks to wateroftyne for helping me host these images. I'm going to email him the new ones to see if he'll paste them over the old ones. He's in the UK, so it might not be until tomorrow his time if he can do this.

I'm on the streamliner train. I tried out a 900 on Saturday at Washington Music Center (Hi Tod and Paul!). I played one note, the cab pushed out so much air the draft moved my pants leg (not to be confused with the up-the-leg thrill of that Matthews guy). Played a couple of riffs, bought it on the spot.

I'll have a review on my website, but in short: if you're a bass player and don't like this amp, you might need to play a different instrument.

Well there's 20 minutes of my life I won't ever get back. Why not start a NEW thread for those of you who like/need this technical information? I for one use the best sensor I know, MY EARS....

It took you 20 minutes to scroll past something you know you don't need or like? :eyebrow:
