Tube amp, whistles and muddy notes

I got my first tube amp today Blackstar ht5 head. I have a few problems, here is signal chain:

guitar-->wah-> jvm overdrive ->amp--> emulated out or effects loop out --> interface line in --> Mac -->headphones

I tested with cab IR's and also its own emulation. And the warm thick fat singing sound I wanted, I couldnt get it..but is slightly better than sansamp(or I dont know how to set it) do you think this is because I dont use a real 4x12 cab and as long as i listen with headphones it will never get a good sound?

Another thing is about pedals, when they are both on, In a certain position wah pedal just starts whistling like crazy also when wah pedal is off but overdrive pedal is on, only in certain "notes" on fretboard, I get this weird noise as if changing the radio station, I play 1 note but it annoyingly alters between 2 notes, shortly that note does not sound clear but gets muddy and dirty, I was able to stop this by playing with the frequency switch on the overrdrive pedal.

Any of these can be a because of an amp/tube problem? Or these extreme whistles and alternating notes are expected in signal chain when using tube amp and I need to adjust my pedals and parameters etc? and dont use wah pedal in that position? which is ridicolus

What kind of pickups are you using? Are they EMG by any chance?

But it all sounds fine going through your 4x12?

Well, the part about the emulation is the fact that they more than likely designed it to sound like a certain mic, speaker & cab combination, which 1: will make it sound like a mic'd up cab & 2: might not be the same speaker & cab combination that you have.

As far as the strange noises go, if it sounds fine running normal through a 4x12, my guess is that it's more than likely a setting on your computer/interface, clipping in the computer/interface, or there's something wrong with the direct/emulation output of the amplifier or the computer/interface.

Feedback from a cheap pedal power supply?

Microphonic valve, perhaps.
