Hi all, Hi FAS
I recentely had some time to check out the Quantum 1.00 firmware. Absolutely great Fender Clean tones, tasty Marshall-esque sounds possible, ODS HRM or ODS with PAB sound good........but the ODS Non HRM (Ford 2) still need some love!
I bought Cab Pack 17, Cab Lab 3 and experimated with different cabs, micing positions, mics.....but it's not there, which is a bit of a bummer!
When I talk about "it", I mean the feel that the amp will jump in your face the moment you pick a note, the beautiful smack when you rake some notes - either on a LP or Strat type guitar, it still lacks of gain and I strongly believe it's just because of the interpretation that an non-HRM model just got the 4.7nF/220k network at the output of V2 instead of the internal HRM tonestack and the rest being identical to a HRM dumble. Which isn't true....
Most non-HRM types using a different resistor network between the clean pre amp and the overdrive circuit. It's almost a 1/10 voltage divider on the non-HRM and also influences V1b in terms of load, which causes the gain and feel difference between a HRM and a non HRM amp.
What I found from my experience modifying the clean preamp and the pre-gain tonestack between V1a and V1b - this plays a major role in terms of feel. I still keep my own re-design of the tone stack and the new bias points "company confidential" - but it would give the tone a very welcome change when FAS could re-calculate the divider network between clean preamp and the overdrive circuit in their DSP code.
There is another small and important thing between OD and PI circuit, which isn't show in any of these schematics floating around the web - some kind of a simple high cut filter - approx. 40k/4.7nF for example does a wonderful job between center tap of the master volume pot and input of the PI - it helps to smooth the tone and cut down the annoying highs... (only works for the overdrive channel but since the AF2 can't clone a two channel preamp in one amp type, it doesn't matter)
The tone and feel is completely independent of the power amp magic - just in case you wouldn't believe, I re-post my clip of my re-revoiced MesaBoogie Studio Preamp which has it all - tone and feelwise - even with a marshall solid state power amp.....

I spend over a year to tweak and re-calculate my own interpretation and I'm so pleased with my results, I don't necessary need this in the AF2, but it would be nice for sure if it would come close to it for sure....
This has nothing to do with picking technique and special mojo.....it's a unique and highly enjoyable tone that make some guitarists very very happy. It's not for everyone and not everyone needs it. I still have some hope it will be able inside the AF2 someday, but this is my very last attempt to beg for this issue....
all the best to everyone
Cheers
