    I just bought a used TFB-420 and it sounds very nice through 2 Aguilar GS112s.

    The obligatory rig pic:

    My question:

    If I run the 'Preamp Out' on the 'Effects Loop 2 Post EQ' to a powered speaker, will this cut off the main signal to the GS112s? I'm hoping that I can run 3 speakers at once, so that I could add a powered monitor to add a bit more sound for me or the drummer, etc.

    Can anyone comment?
     
  2. Only one way to find out... plug 'er in and see what happens. I would suspect that you will not be sending a signal to your primary rig when you plug into the pre send.

    It seems that you would want a 'post EQ' signal going to your powered cab. So, if you powered cab has a 'low impedence mic input' you could take a feed from the post EQ low impedence DI... that should work great.

    unless the loop is serial, it should work fine. but test it out. hook up your rig, and w/ an instrument cable, plug into the send of the loop. if the sound totally cuts off, then no dice. if it doesnt, then yay!
     
  4. +1 I forgot about the serial/parallel loop thing.

    Thanks guys. I put the Post EQ out jack to a 25 watt guitar combo and fretted the G-string. The Aguilars are still on and overwhelm the little combo, but it seems like it's playing the notes as well.

    Another question: How do you set the gain/volume controls? Is it like the gain on my power amp and Volume on my Pre?

    The gain is supposed to be preamp gain according to the manual. So do I dime the Volume control and adjust the preamp gain to taste? How do you handle it? Compressor settings?

    Coming out of the FX2 Send does not disconnect the loop, so both amps will work. It's when you plug into the RETURN that the loop gets broken.

    The GAIN sets the Limiter. Usually set both GAIN and VOLUME to 5. That should give you the lowest noise. Then adjust for the amount of limiting (compression) you want with the GAIN and set the VOLUME for VOLUME. Download the owner's manual from my webpage.
     
  8. Depending on the output of you bass and your playing style, assuming you just want a little bit of limiting to take the edge off hard hits on the B and E string, the gain control will typically be set between 11 and 1 o'clock. I usually set this with the volume turned almost off so I can really wack on the bass and make sure that the limiter only kicks in (i.e., the light comes on) on the hardest and lowest notes. Once you have that set, then the volume control acts as.... a volume control!

    Congrats on a great looking purchase (I own a TFB550 and love it).. On the TFs, the Post-EQ loop Return cuts the preamp section out of the loop, and sends to the power section whatever is coming in on that line. This is the input you hook up to slave a TF. So as long as the Send signal on this loop is coming back through the effects processing, you are getting your signal off to the power section (and presumably out to the speaker).

    Thanks guys.

    This amp has really grown on me in the first couple of days.

    Wow, that is an AWESOME rig. You've got SO many bases covered so efficiently with that particular gear. This has to be the perfect example of being able to do anything, and do it extremely well, without having way too much stuff.

    Props, dude. Awesome choices. I bet your tone is incredible.

    i swear, that rig is just plain pretty. i can easily see that as the rig build towards (well, with a pseudo-thunderfunk at least).
