Subject:V3 effects out and back into V3 in questions.

I read the following posts from way back.

snip>> Hi everyone,

I bought a Spin and I found it to be considerably less noisy coming
from
the
effects out of the V3 rather than using the internal V3 simulator.<<

Dean goes on to mention that he finds the output too hot for the
external spin, and Bruce replies with a small circuit diagram for an
attenuator.
My question are these: Is there any benefit to be gained noise-wise
from by-passing the internal connection and feeding the V3 straight
out (perhaps into an attenuator) and back into the internal SPIN? Is
the internal SPIN essentially the same as the external SPIN and was
the extra noise caused, when using the internal SPIN, in some way
due to the actual internal connection from organ generator to SPIN
picking up noise inside the unit?

Has any-one by-passed the internal connection in this way, or is
every-one doing it, or did Dean find the external SPIN less noisy
because the effects output from the V3 was 'too hot' so he was
reducing the overall volume to compensate and thus reducing the noise?

Finally, obviously I could just try this out, but is there any
technical reason for not doing so?

Thanks Thomas.

external SPIN.


Dean,

You need to buy -- or make -- an attenuator of some type. The easiest
thing would be to put the following in a small metal box:

_ TIP 10K, 1/4W TIP _
1/4" | | \/------o------######------o----------o-------\/ | | 1/4"
jack | | RING | RING | | jack
|_|---------o------| 10K # |--o----------|_|
| 1/4W # |
| | |
|-----------o-------|

This will drop the output about 6dB, which should help. If that's not
enough, substitute a 20K (or 22K) resistor for the "horizontal" 10K.
Make sure the box is closed with metal on all sides to minimize noise
problems.

Alternatively, you could put a 50K or 100K potentiometer in the
circuit,
to allow adjustment to suit your needs.

Regards,
