I also started to doubt that the clipping is affected by one of the trimpots? Or am I completely off with this?

I also noticed that the 4x MN3008 is calibrated a bit more different than my 2x MN3005 version.

Here is a picture of mine with the input resistor connected to a pot, for easy impedance adjusting. I just can't find my mind around the 'clipping' overloading problem on the repeats. I tried to switch out R27 100k on my board as you see on the right side with a pot as well.

[FONT=&quot]By increasing R27 (100k) you lower the blend of the repeats to your dry signal. However it also has the negative effect on the feedback that is not able to go into self oscillation on higher values of the trimpot...[/FONT]

Am I looking at the wrong resistor to change?

Hallo,

I'm not German, yet I understand a lot from this thread knowing Dutch.
I hope you are willing to help me, I live right next to you actually. (Belgium)

What I understand is to get more head room, you can simply replace U1 to a OPA2132 op-amp? I already replaced all op-amps to TL072 and this indeed improved the tone but not the headroom.

After that I put a trimpot at the input resistor of 100k. This lowers down some volume (when you play guitar with a hot output). I found out a Value of 120k to 130k is perfect. This also lowers the clipping a tiny bit.

And now for the final touch to stop the clipping as best as possible, there should be another trimpot involved to lower down the gain!

Any help or input is so welcome!

thanks in advance
