I used on the mid switch #2, boosted the mid up to about 2 o'clock, pushed in the bass boost switch and dialed in the mid highs on my Deluxe P. Big HUGE B string notes. Especially low D. Killed it. Even my LOB wanted me to hit that low B and usually he hates those notes. I thought that was a pretty big compliment as well.
Right on man. A lot of folks around here say stay away from the Ultra Low button. I disagree though. You can use it in a mix, you just have to add mids. If you dont you pretty much get burriied, but I dont dig the wooly tone of Ampegs without the Ultra low button enganged.
I posted settings similar to that earlier in the thread. I love a big crushing low end myself.
Here is the settings i usually rock again: Try them out and see how you feel.
Note: I run these settings with a Heritage SVT410HLF. Its a ton of lowend. It cuts through really well though believe it or not.
Gain: 12-2 oclock
Compressor 9 oclock (I used this because since i run Octave pedals and distortion it smoothes things out for the cab)
Ultra Low engaged - Ultra High not engaged
Bass 3 oclock (dependign on the room sometimes less)
Mids 2-3 oclock
Mid Selector mostly position 3, (sometimes 2 if the room makes the cab honky)
Treble 12-1 ocloock. On this one i sometimes roll back the treble if the sound gets to sizzly..
With a low B this sounds awesome.. big thunderous lows. My guitar player generally plays a 7 string Stephen Carpenter sig through an all tube Peavy. Some serious metal crunch. And with my settings we dont fight over frequencys. I sit right below him with my 5er. Its pretty sweet. I also dont get in the way of the kick...
Glad you found a tone you like with the 7pro. Ampeg to me is very very good tone.. it does seem like each amp has a sweet spot though. I dont to dig all the tones from ampegs. I can always find a spot I love though.
