Dear all,
I am using an FM3 with SS amp and Marshall 2x12 V30 guitar cab. I mostly use classical Marshall amp models without master volume, like Plexis, aiming for AC/DC-like sound. Typically, in my grid I will only have an amp block and no cab block, since I am using a physical guitar cab.
For a long time I had problems dialing in a good sound with this setup, most of the time the sound was either too bright/harsh or something was missing more to the low end. Since I am running my SS amp at lower volume levels than what the actual amps would achieve, I started to think that maybe the problem had to do with frequency-dependent perception, i.e., fletcher munson curves. As an experiment, I took two equal loudness curves for different volume levels and calculated the difference, yielding a "correction curve" corresponding to the difference in perception between my SS amp volume and the actual amp at the used settings. (Of course this is just an estimation.)
Using the obtained curve, I placed a graphic EQ behind the amp block and configured it correspondingly, so that the EQ would do the necessary correction. Indeed this seems to significantly improve things, the sound I get this way is much more credible and usable. In short, what I have done is simply something like an implementation of a "loudness button" one can find on hi-fi systems.
Now, I have some questions. First of all, are my considerations reasonable and would this be the way to go for getting more realistic sound? And furthermore: Doing these calculations and dialing in a graphical EQ by hand is error-prone and one might get better results when really knowing the right correction values and having a precise such EQ. Hence, I am asking myself if such a feature would be interesting to have in the FM3, i.e., some kind of "loudness block" in the grid to more easily and precisely get the necessary corrections.
I think my problems dialing in a good sound might not only apply to extreme cases like an incredibly loud Plexi vs. bearable volume levels but also for amps with master volume, since I have e.g. tried the JCM 800 model. For me, it is really hard to know which master setting in the FM3 combined with SS amp settings would be equivalent to the actual JCM 800.
I would also be interested in any comments from people who are using the FM3 with a SS amp + guitar cab on how they achieve a good sound.
