Rustbucket 'False/Re-Triggering' & can I make it less distorted?

[fman7]

Hi,

Built a Rustbucket, and worked as soon as I plugged it in, however, now I've tweaked the Bias Trimmer I seem to be getting a lot of false and retriggering of notes, should it matter where in the signal chain it sits? Any sweetspots for the front panel controls?

Also, was wondering if changing the resistor in the feedback cct of IC4B would clean the signal up a bit so it doesn't sound distorted, more clean/neutral?

thanks

Frank
