Buffering, loads, and rack effects

[frizbplaya]

Sorry if this has been discussed before, I'm new here and couldn't find a search page anywhere. If it's been dragged through the mud already just point me to an old thread and I'll be happy to read!

 

 

I'm thinking of getting a rack equalizer (Ashly Audio MQX-2150) and I'm worried about feeding my amp the wrong ohm load and changing the way my pickups interact. I know just enough about gear to be worried but not enough to know whether there will be problems.

 

The EQ is listed as:

Input Impedance: 20K ohm Balanced, 10k ohm, Unbalanced

Output Impedance: 200 ohm Balanced, 100 ohm, Unbalanced

 

The EQ will be last in a chain of all true-bypass pedals. So far all my effects have been specifically designed for guitar so I just don't know how rack gear will affect things.

 

my questions are:

 

1) Will the EQ be sending my amp a lo-Z signal and will that hurt the amp or atler tone?

2) Will the EQ affect my pickups by being lower ohm (pretty hot humbuckers from Gibson ES-137)?

3) If there will be problems with either, what can I do? Buffers?

 

Thanks a ton!!

The output drive at 100 ohms is fine - very low Z and will drive your cable with no problems.

 

The input z is quite low at 10k. This will load your guitar pickups and have an adverse effect on tone. It will be most noticeable when all the pedals are switched off. You probably need a buffer before the EQ, or a buffered pedal in your signal chain before the EQ.
