Star Chamber MXR M118 delay clone : possible issues with other buffered circuits in the signal chain.

Well-known member
I noticed that my Star Chamber build has a weaker delay with less amplitude and repeats when i engage some circuits before it.

For example a looper/mixer/blender circuit (Pro-cessor from TH Custom Effects), or even a Boss GE-7. I also have this drop with the delay response after a little EQ circuit (Guitar PCB's Tone TWEQ).

The delay still works, the clean signal remain the same, but the delay's amplitude and fullness are dropping noticeably. It's back to normal if i disengage the effect i tried to add before the delay.

No issues with some buffered compressors like Walrus Deep Six or a Guyatone PS-20 clone.

It just seems like it doesn't pair well with some circuits. I never had this issue before with analog delays.

The Star Chamber delay is among the last effects in the signal chain, the GE-7 is connected just before it. There are several other buffered circuits in the chain before the M118 clone.

I wonder if it's about signal impedence or something ? Are vintage analog delays known to be sensitive like that ?


Every observations and suggestions are welcome.
