Hey, I was just wondering about all you other fellow 680 owners and your settings for this preamp? I'm just curious to what all possible tones you can dial in and such. Please tell me all about it! Tell me what bass you use, what music you play, even what lvl of volume you play at, and of course your setting on the preamp + what power amp you have and cab. Thanks! Heres my settings... I use a warwick Corvette 5string (i have bass and treble at the mid setting) into my 680. I have a BBE sonic maximizer too, I run the high and low settings on that at 2 o'clock each. Now for the preamp, I have the bass at 11o'clock with the deep switch off. the low midrange parametric pot at 880 with the cut boost knob at 9/10 o'clock and the high mid parametric knob at 10 o'clock (i cant remember the frequency it on) and the boost/cut knob is at 10 o'clock. for the bandwith on the high and low mids is set around 9 o'clock (grabing quite abit of surrounding frequencies to the ones i isolated) treble is around 11 o'clock with bright switch off, sometimes on. My master is all the way up with my gain at like .5 I go into a peave cs 1400 power amp (bridged 1400 watts @ 4ohms) into an ampeg pro-410hlf cab. I play at rather loud average volumes (nothing INSANELY loud) but if i have to I have the head room to turn up. I play in a rock band playing all kind of stuff. I'm mainly going for a nice fat clean sound that has some bite to it and can be heard clearly through the mix. I think this accomplishes this pretty well but if any of you have better suggestions I'm totally willing to try them! Thanks So tell me your settings and what youre going after.
