Can an SF2 be used in instead
of the F1X or do i need the F1z to drive the SF2?

I ask because i am putting together a small simple rack rig and was thinking of using the f1x and a plx power amp.

Hi....
Either one can be used as a preamp.
The SF-2 I think would be considerd more unconventional in the preamp arena, most use the FX-1 as there Main pre, but in a pinch the SF-2 has an instrument input jack on the front for that reason.

There are several folks here in the forum that use the SF-2 as a preamp; so no, the F-1X is not required. However, from a tone standpoint they are not the same thing.

Their utilities are totally different. The F1X is an updated, vintage design tube preamp (modeled on the Fender Dual Showman). It is very strong on warmth, clarity, "tuby" crunch - all the things you'd want in a tube preamp. However, despite some nice features (effect loop, controllable, internal crossover, direct out), it has only the most basic EQ (t and b boost, mid cut). That's where the SF-2 comes in for lots of us. Bottom line, the F1X is a really sweet-sounding tube preamp, but not a "swiss army knife" type of sound shaper like the SF2.

The SF2 alone would definitely stretch many folks' definitions of "preamp", because of its incredible array of 2 setable filters (can be low, high or band pass), plus mixer to blend both filter channels with your non-filtered signal. As if this were not enough ("But wait - there's more!"), the SF2 also contains a nice solid state preamp circuit. As Tom said, it's brought online by plugging your instrument into the front input jack. But, being strictly solid state, the SF2 preamp is less dynamic and pleasant to my ears than a tube preamp.

Bottom line - on those rare occasions that I have to do without my F1X, the SF2 is an adequate backup preamp. However, the SF2 does its best work when just filtering and mixing a tube signal.

My X-mas wish: Combine tube preamp in the same box with the SF2. I'd marry it and we'd sail off into the sunset...

Bill,
Isn't the F2B the unit modeled after the Fender? and the F1X a variant trained to do different tricks?

Great question. My understanding was that both shared the same Fender heritage. However, as I look at the product specs, I'm wondering whether I gathered that opinion on this board or, if not- not sure where? Can anyone add any info to this one?

It states specifically on the F2B page that its directly realted to the fender, for the FX-1 it simply says this
"The tone controls are the interacting Fender circuit".

The F-2B is a two channel preamp great for stereo applications. The FX-1 is a one channel preamp (basically half a F-2B). Both are modeled after the Dual Showman's preamp section.

But they are so sweet together! I prefer the F1X-SF2 combo. Use the SF2 in the FX loop of the F1X. Get them ASAP, Just my 2c on the QT IMHO bros!

I asked about FX-1 vs. F2-B while I was at the factory yesterday. Here's the lowdown: Both are based on the Fender Dual Showman Pre-amp. The FX-1 has a single channel pre-amp and a crossover circuit for bi-amping. The F2-B has two channels but doesn't have the crossover.

The F-2B also doesn't have the deep switch, effects loop, or DI (that the F-1X has).
I still prefer the F-2B for it's simpler circuitry and extra channel, because I don't need those extra things that the F-1X has.
