Mailist to discuss all issues regarding the Digitech GSP-2101 Guitar FX Processor

It's taken a bit of work, but I've gotten, at least what I consider to be a
good sound out of the Dual Chorus, and the Stereo Chorus.

I've also had a bit of good luck using 2 mono Detuners for that Van Halen
type sound.  One is set a bit flat, and the other is set a bit sharp.  But
the two main patches I use both have chorus on them.

Blessings,

Brian

Here's what I have found, and it's very obvious...

- Some effects sound better then others;
- Some effects take more processing power then others;
- Not all effects modules take the same processing time;
- The same effects modules take the same time to process the signal no mater
how many, or how less effects you place in an algorithm or their sequence;


What does all this has to do with converters????
- Nothing and everything.

So:

1\ufffd - If a module is not very good, sound won't be good no matter how many
bits you have in the A/D or D/A converter (not talking about extremes like 8
bits of course, talking about 18 to 20 or 20 to 24).

2\ufffd - If a module takes to much time to process your signal you tend to think
it's not so good because your hands and ears are expecting something they
find normal (action/reaction).

3\ufffd - If in a module the sound if mixed with it self and or modulated, it's
normal that there will be some wave cancellation effects and frequency
boosts.

Conclusion:

My message about trying to get help to improve the quality of the sound by
changing the converters is unnecessary.
I was trying to fix something that could never be fixed. It's true that it
might improve sound a bit, but not so much that I could say it makes sense
to do so.
When using modules such as Detuners and Pitch Shifters sound tends to be not
so good and there's no ADA converter in the world that could improve this.
If I want the high quality version of this effects I have to buy a faster
and more powerful unit like the TCElectronic (the 2120 has some high quality
ones too, unfortunately not as good).
I love the 2101, it's the best unit I have ever had not because it sounds
ultra cool, but because I can do everything with it. Along the years I have
learn to love this machine and live with its flaws and walk around them.

To end here's a list of the effects modules not so good that can damage your
sound if used in line (unfortunately some of them sound better like this and
not in parallel):

- 4 Phase Chorus
- Stereo Dual Chorus
- Pitch Shifter
- Dual Pitch Shifter
- Stereo Pitch Shifter
- Smooth Pitch Shifter
- Mono Detuner
- Dual Detuner
- Stereo Detuner
- Harmony
- Stereo Dual Detuner
- 4-Voice Detuner
- Arpeggiator
- Stereo Arpeggiator
- Whammy
- Programmable Whammy
- Smooth Whammy

Hoppe I could help any one that felt like the 2101 was not up to the job any
more.

Please say what you think about the modules I chose, please tell what are
the one you think don't belong in the list and the one that should be.

2101 RULEZZZZZZ,
Pedro Ferreira

Pedro,

Forgot to suggest something to you.

Pick any patch you don't use on the 2101. Edit the algo and get rid
of everything in it. Save the algo. Go back to the program and turn
everything OFF, turn volume to 0dB and EQ totally flat.

Connect your guitar to the 2101. Connect the 2101 FX loop send to
your new pre-amp input. Connect the output of your new pre-amp to
the 2101 FX loop return.

Go to the last module/step of your program on the 2101, which ought
to be the global wet-dry mixer. Crank it all the way to WET 100%
(although if you've done everything I've said this shouldn't matter
at all).

Play. If you feel there is a noticeable difference, please write
back telling us, and you might need to buy some other mFX. If not,
then you will contribute supporting our findings and the 2101 should
be just right for you.

Seriously, in doing all this, I also came to realize that there are
several aspects involved in the algorithm programming that can
affect your sound (positively or not, it's up to you to judge it)
that you have to be careful and keep this in mind in order to really
obtain the most from the 2101. Please, let us know.

Gus.
