Metro Loop problem?
Posted: Wed Nov 23, 2011 2:12 pm
Hey guys. I have a 68 plexi clone that I installed a metro effects loop on. I have also installed a normal master volume (like a 2203) as well, and the loop is installed before the MV pot.
I'm not certain it is functioning properly. I only use it for a delay and using an El Capistan.
I'm having two issues. The first is that at higher frequencies (not sure why it would be limited to highs), I get a nasty sound as the delays repeat, or on the first repeat anyways. It almost sounds as though it's overloading something and getting distorted. This is with the mix around 35%, it only gets worse as you approach 50%.
The other issue (although maybe not an issue) is that I've never felt it "wet" enough. It reminds me more of a delay in front of the amp as opposed to a delay in a loop. Not sure if that makes any sense to anyone. Just not quite what I expected from past experience with other loops.
I don't remember the voltages I measured when assembling it, but all the measurements when done was well within the values posted in the installation instructions. I think I used the 10k resistor.
I tried another delay over the weekend just to see if it was the delay and I had the same issues. I used a Glab smooth delay with an input gain adjsutment figuring I could eliminate a potential overloading problem if that was the case. Same thing. A "rough" top end during delays and a feeling of a in front of amp delay as opposed to in the loop.
So, my next step is to start over with the install and make sure everything is correct again. However, I did read on another forum that some people used a different "component" for better results. "Component" perhaps meaning a different B+ resistor value. I asked about it but was ignored, so that is the only info I have.
Anyone have any issues similar to these or any thoughts on what I might could look at that might cause any issues like these?
