i then took a look and noticed that you have a whole bunch of parameters that are way off default. bias up full, compression up full, damp up full, active depth (but depth on zero)...
I am still at my 'regular work' and will not get back to my studio today. But there is a public holiday in my part of Germany tomorrow which gives me the time to record and post it here. Thank you for dealing with this problem, electronpirate.
It's not string buzz, it's distortion. Like Simeon said, with insane settings you may just get insane results
I checked out the patch. You have some seriously hot pickups...I had to raise the trim a load to get into the same breakup territory as you. I get similar results then. You've got Comp in the amp block at 100%, Dynamics at +50% and an additional -15 - 20 dB reduction with a compressor...full bias, full damping, xfrmr match 0.1...You're not gonna get yer everyday tube amp sound from this!
that keeps nagging me
By listening to that clip I can imagine that. Can't imagine that anyone wants to make the audience endure this. I'm not talking about the breakup though.
Sorry if this sounds harsh. But it's as harsh as that tone.
