I am becoming a huge fanboi of the Fortin 33. I've had one a few days and after adjusting to it, it really sounds great to me into a Marshall. Power cords on the 8th string come through nice and clear. It's quite bright and thin but somehow still chugs. Has a very mean/angry sound but is sweet/warm on the top end.
I've been going nuts trying to find an amp and pickups that would do what I wanted and the 33 seems to have solved my problems. I can still use my beloved Marshalls and passive pickups but just boost with the 33 instead of an SD1 or 808.
Slightly off topic: is the 33 out of production? And how does the Grind compare?
