Andy, I checked out your web site, nice site! A very impressive group of photos in the friend section. I too am an underwater bass player.
Nice photos there too. And your personal quote is also one of my favorite scriptures, Proverbs 17:28.

Peace, Olie

I personally would not attempt a Navigator + SF2.

I'm a big Eden fan (this METRO stack in the corner makes me mighty happy). The EQ was obviously thought out by someone who REALLY thought about it a long time, and the Navigator has more than this. But I would shudder to try and send the complex Q these front ends can deliver through an SF2. I definitely believe that less is always more and the moderate tone control that the F1X offers is plenty to contemplate sending through the SF2. I think it will be a long time before anyone EVER duplicates this piece in terms of what it's capable of while not changing the phase relationships.

The BigRedBass (soon to be the BigRedFatBass, the FatBoys are on the way ! ! ) at first was a real mind-blower as it's a Spoiler. What the hell was I gonna do with a vol, tone, QSwitch, and pickup selector? Where's the bass, mid, and treble cut/boost? The balancer?

Well it turned out that I could do more as it was just so right to begin with. So I didn't need much. I run the METRO virtually flat. IT doesn't need much (especially sitting on top of its 115XLT cousin). And yes, I NEVER use the Enhance, either.

It all really makes me think of a Series straight into a power amp straight into a cab.
I was knob-crazy for years, now Ron's really broke me of it. Having said that, I'm sure I'll go hear somebody this week that's playing through a very long chain and think it sounds just as good. Crazy, ain't it?

I have an Eden Metro Combo. SOunds good but I have had some problems with it. I bought it new when they first came out and have twice had to have it repaired and now for third time it needs to go to the shop. The same problem all three times. A long slender, looks like a balast resistor, comes loose then breaks and has to be replaced. If I could solder worth a flip I would fix it myself.

Looking at the Metro channel 2, it appears to have the same tone controls as my Navigator. I find them quite versatile and agree that trying to add an SF-2 would probably make the whole setup unmanageable. I have enough problems with what is there. I have found that I keep the controls close to flat and at their mid-range settings. Unlike others I do use the Enhance somewhat. I keep it set around 9 - 10 o'clock and then use the footswitch to turn it on or off. I use it much like the Turbo Boost for when I want that little bit extra (my controls don't go to
11 :-) ).

I've yet to find a use for the Enhance button. Regardless of it's position, I find it thins out the tone and adds unwanted distortion.

Joey: Your point may be well-taken about not wanting/needing to add an SF-2's twists and turns to an already refined signal. I've also heard a lot of folks who don't use the enhance button on the Navigator, too. I have no hands-on experience with the Navigator to know, but, Jeez - you're more than likely right. I have learned, time and again, that simpler is usually better. I guess I may have to try things out and see. Thanks.

...speaking of damping factors...(fastness),

does anyone know how the numbers are affected when running a SF-2 (damping factor turned up) ,with a 'fast' power amp?
I just bought a stewart world 2.1 and am in sonic heaven : ) thanks to all the good advice here...

That's a different kind of damping factor - I seem to remember reading that this control on the SF-2 is similar to a CVQ control on a Series II bass.

When talking about power amps, isn't damping factor something to do with how the amp keeps a handle on the current flowing back from the speakers? Sorry for the vague recollection ...

Okay, so I'm thinking about a power amp too. I'd like to go with the PLX2-1804 to save a couple hundred dollars and 8 lbs in the rack over a PLX2-2502.

The extra money and weight buys you some useful filtering, dual mono from a single source without a jumper cable, and some output flexibility. Then there's the difference in the specified damping factor. I'd like the subsonic filter protection and wonder about the import of the damping factor in practice. Other than that, I'd order an 1804 this week...

The older 2402 model definitely looks like a bargain right now, but I don't fully understand the differences between the PLX and PLX2 lines.

Bob,
Call QSC to see what the differences are between the PLX 2402 and PLX2 2502. I found them helpfull when I was looking at my PLX 3002. Given the closeout prices for the 2402's my opinion is to go with it. It has the built in limiters, filtering and paralell inputs of the 2502.

Thanks Keith. I think the 8 lbs might be more important to me if the damping factor is a non-issue.

The only thing that keeps me from looking at the 1804 is the inability to run it bridged mono.

Thanks, Olie. That's quite collection of basses you've got. So...Who are the girls in that photo?

Groupies man....groupies..........NOT!.
They are actually the DOS XX's girls. They were on the beach in Progresso, MX. My wife took the photo.

. I have 2 daughters older than them!

I don't care about bridging the 1804 as long as I can run one side alone for small gigs. 900 into 4 is plenty of juice for me.

Fot a two cab gig, you just add a jumper cable to tie the two channel inputs together.
