Try as I might, I can't find a built-in OD that sounds anything like my FD2 MOSFET. I know it's in the Screamer family - and that the Tube Driver often rules and was my old go-to OD - but I'd dearly love to emulate what the FD2 is giving me. Yes, I can take it along, but prefer to let the HD stand alone where possible. The pre-MOSFET FD2 was easy to emulate, IMO. But this new one is much more powerful sounding to my ears and the Screamer doesn't even come close. The FD2 is running in FM and MOSFET mode and is not in the HD's loop at the moment. OD level is fairly low - about 9:30/10:00. In case it matters... I know there are many skilled HD tweakers here - can anyone help? Even if I have to combine two built-in ODs? Thanks!
