GK MB200 owners: contour switch on or off?

Title says it all; for you GK MB200 owners: do you usually activate the contour switch or not?

I found that with my speaker/bass combination, I pretty much keep it on all the time.

Edit: I should add that I have a PJ Bass with Flats and GK MBE212 speakers
 
I never use a contour switch on any amp I've owned. It's just another word for " scoop ", a sound I don't care for.
 
I keep mine off. The scoop is too extreme for me with it on. Although I have played around with it on and then pulling the lows down and putting the miss back in, just provides some different sounds.

I'd prefer the adjustable contour knob.
 
I used an analyzer to find settings that are very close to flat:

Contour = Off
Treble = 10:00
Hi Mid = 2:00
Lo Mid = 1:00
Bass = 10:00

Of course "flat" is not the be-all and end-all, but I find it useful to know how my amps work. Also, my speaker designs all assume a flat amp.
 
agreed, flat is a very overrated concept for musicality, but tbh i think the differences between amps may be way way less that we all here at TB think if A:B comparisions were used with the amps performing with a flat response, rather than 12,12,12,12

Hmm... an interesting thread idea.. post Analyser screenshots of amps with controls set for flat response?

That's about how I run mine.
 
One could just add a tone control bypass switch, which would make the amp flat if the preamp and power amp are that way.

The old West Laboratories from the early 70 s did have a tone bypass switch. It was marked L.O.U.D, and when engaged would rearrange the neighbors china cabinet. Keep in mind that in those days, if you turned all the tone controls to zero, you would have no sound. Bypassing the tone controls was essentially "these go up to eleven".
BTW I leave the contour switch on with my MB200.
