Thanks!!!

Between Gain and Drive are three preset button-activated EQ shapes: Bright (adds ‘presence and shimmer’ at the top end via +13dB@10kHz), Contour (scooped mids, or -13dB@670Hz, +1dB@80Hz, +2dB@8kHz) and Vintage (which squashes your tone and darkens the midrange via up to -9dB dynamic compression with low pass). There’s also a simple four-band EQ numbering Bass (+/-15dB@80Hz), Low-Mid (+/-12dB@280Hz), High-Mid (+/-12dB@1.2kHz) and Treble (+/-15dB@10kHz). On the back you’ll find jack sockets for extension speaker, FX loop, Aux In, phones and the footswitch plus an XLR DI Out with Ground/Lift switch.

Unlike speaker builders, guitar amp manufacturers do not release frequency response data. It seems they obscure it.
Test procedures described by schematics are usually only at 1KHz.
Unusual knob settings are also specified, such as ,"Treble at 10".
I'm sure that their competitors know how to plot response curves as well. It's a basic engineering exercise.
Why it's such a secret, I don't know.

Thanks TimsAudio and stratele52 for your immediate reply.

I was planning to compare the frequency response of the Rumble 500 with a stage monitor. I would like to determine if the stage monitor I am eyeing is capable of handling the low frequency response as compared to the Rumble 500.

I guess I just have to deal with their secret. :lol:

Well, you can count on the stage monitor to have flat response 20-20kHz.
While many bass amps also have flat response, most of the SS Fenders that I have measured have shaped response.
A good bass DI box on the monitor might work, but in general, I would recommend an amp that is designed for your instrument, not a general purpose device.
