The sliders will flash if ur input voltage is low - if u have a defective power supply or are running 9 volts into it for example. They can also flash if there's a short somewhere in its electronics

And I bet that the chips aren't socketed either are they?


Nope. Soldered on the board. I will keep mapping out the signal as time permits. Sucks the schematic I found is wrong.

See, it's important that people clarify when they say "metal", because I pretty much always assume they are a Cannibal Corpse fanboi.

I have no idea what actually might have happened to mine. Maybe I jut didn't have my power supply fully plugged in or something.

You should be chasing unity. You don't want the loop to be anything else either. Setting the send and receive to about halfway and adjusting them both about the same amount until you achieve unity is where I'd start. The pedal should never clip so adjust its gain accordingly once you've set up the amp's loop - then chase unity through the pedal using the output volume. Done.


That's more or less what I've done. Luckily, Bruce was pretty thorough with the Vengeance Manual. Here's what it's directions say:

Quote by Egnater Vengeance Manual
a) Set your amp/preamp volume
levels for normal playing levels. Connect
a high quality shielded cable from the
series send jack to the effect input.
b) Adjust the send level to “just
peak” while playing your most aggressive
licks.
c) Now connect another high quality
shielded cable from the effect output to
the return jack.
d) Adjust the RETURN level to
match the volume you heard before connecting
the return cable. You can check
this by turning the loop on and off while
playing and verifying there is no substantial
volume difference. This is called
“unity gain”. A cool “techie” phrase for
“you get out what you put in”. If your effects
gadget does not have level controls,
it can be assumed you will get unity gain
when plugged in.
e) If your effects unit does not have any
sort of level indicators (LEDs, VU meter
etc.) you would likely not know what
the proper setting for the SEND and
RETURN levels might be. If this is the
case, please follow these instructions:
1) Connect your effect to the SEND
and RETURN jacks and turn the effect
on. Switch the loop off and listen
carefully to the clean channel. Set the
RETURN level to about noon and the
SEND to ‘0’. Turn the loop on. Now
increase the SEND level knob until you
start to hear clean, undistorted sound.
Continue to increase the SEND level
knob until you start to hear distortion
or loss of tone/high end. You have
now identified the overload point for
that pedal. Now back the SEND level
down until the distortion disappears.
Lastly, while switching the loop in/
out, adjust the RETURN level until
the volume is equal with the loop
switched in and out.


I've followed those directions, so am I good to go, then?

Yeah, that all sounds about right. I would also check for unity through the effects loop itself by using a patch cable between send and return.

Okay, I'll make sure to do that

Really, though, is there a point behind having unity other than to make sure your amp is the same volume with the loop on and off? If that's the case, I really have nothing to worry about, considering I ALWAYS have the loop on for my drive channel and NEVER have it on for my clean channel. In fact, the only thing I use it for is to make some space for our bassist in the mix with my EQ and to cut extra noise with my Decimator, both of which are only necessary on the overdrive channel (for me).

Chasing unity is important to ensure that everything is working in the middle of its operational range. If you don't chase unity you can end up overdriving one thing and over attenuating another. A noise gate should be used as a last resort except when using it as an actual effect. We see this all the time:
"amp is noisy"
"Get a noise gate."

Wrong - try to fix the amp and if you fail at that then try a noise gate. A noise gate should not be the first response. That's tantamount to turning up the car stereo because the diff is noisy - fix the ****ing diff!
