Might be worth looking in side of the Bass Cab and seeing if the walls are lined also. If not, Its a cheap mod, (10$ish) and can make some cabs sound "cleaner".

So I had a living room rehearsal for a few songs last night. The amp was right on the floor and my wife was all acoustic (guitar and vocals). We were trying to be on the quiet side, because teh kids were sleeping.
My TKO was set like this:
pregain: 7.5 (about 2:30 in the "clock" analogy)
bright: out
contour: out
low shelving: 3 (1 o'clock)
high shelving: 0 (12:00)
40hz: -15db
100hz: -3db
250hz: -2
625: +8
1.6K: 0
4K:
10K: -15
master volume: 1.5 (8:30)
I'm playing a Warwick FNA, active electronics set about flat, sometimes with the bass and/or mids boosted a bit (under 50%)
The bass sounded loose and undefined. Especially when we got going and our volume got higher. However, I started to lose volume, and then the lower notes really started to make that "farting" sound. I checked my battery, and it was still sending about 8.5 volts. (I used a multi-meter) I read somewhere that they usually need to be replaced when they're around 7.5 volts.
Not sure what to make of it all. I think I'll try boosting the EQ around 1.6K, but I don't like that "glistening highs" sound so much, so hopefully I can avoid that.
MAybe I just want a new amp. I played an 800RB once that I just loved![]()
animvl said:Sounds like an electrical fault though, did you have the same problems at the venue or did that sound muddy without the electrical fault? If you had the fault at the venue then it's not worth attempting to fix anything with EQ until the faulty part is replaced or fixed.
