This is an easy question but I can't find any easy answer..
I want to connect a rackmount audio effect output (line out)
in a guitar amplifier input (in clean mode).
I read that I should attenuate the line out signal to 1/10
from it's original level to avoid distortion in the guitar amp..
I was thinking of using a 2 resistors attenuator circuit
around 22k & 2.2k in series with incoming signal at
22k and the output tapped at the 2 resistors join
The final 2.2k end is grounded.
Is-it a good ratio to use ?
Thanks.

This sounds fine - and will give you slightly over 20dB of attenuation.
if you need more - just reduce the value of the 2K2 resistor until you arrive at the desired result.
Don't be afraid to experiment - no harm can be done, as long as you keep the volume low.....!

thats what the input control on the amp is just turn that down. Or turn down the output of the effects box
You probably don't need to do anything. Most modern guitar amps are designed to accept line level outputs from pedals. Not 100% sure, but worth trying first.
rackmount effects and guitar amp inputs can get along, as long as operating levels and impedances are happy with each other.
some units have provisions for selecting between -10 and +4 db operation (common on many Yamaha rack mount units as well as Roland, Lexicon.Evintide etc)
will your guitar's output level and impedance be sufficient to drive the unit in question?

If you don't have output/input level controls on either device (which seems implausible), it might be better to use an audio taper pot so you can adjust the level to your taste. Similarly you could build a simple variable gain op-amp stage to buffer the impedance if necessary.
But yeah pretty much this. If it's an old amp, then MAYBE you need to resort to an extra device.You probably don't need to do anything. Most modern guitar amps are designed to accept line level outputs from pedals. Not 100% sure, but worth trying first.
