Glitterratti upgrade suggestion

[Freddy900]

I  am just arrived in this wonderfull forum!
Here annex you can see my selfmade tube amp: italian 1"1/4 solid old wood, celestion G12H vintage, one 6L6 and two 12AX7's Single End Class A 5-3 watt.
Now, I have just ordered a Glitterratti pcb and I ask you some suggestions about:
1) which op-amp just to obtain a smooth compression,
2) do you know anything about "clipping option"?
Thanks! ... an old italian guy

Welcome!  The glitteratii is one of my favorite overdrives. It works well with a 4558 or tl072.  I would build it stock and then tweak from there.  Even stick it sounds really nice. Ciao!
