I didn't have time to do a proper stereo link, so gain for both channels is derived from the left channel signal (when the stereo mode is turned on). It should not destroy the stereo image, since gain is same for both channels. I'm looking into this.
Yep, changing bias produces crackling noises, because all capacitors need to charge to new values (this control was an internal trim pot on the original unit). I will fix this in future versions.
Well, you did it again. This is very nice. Probably the best chimey fenderish tones yet. Not being familiar with the hardware, I youtubed it. Wow, that is an impressive unit. I spent a few hours with it using gtr. There are so many great things about this vst. First off you really have total control with out being limited to any particular voicing (fender, marshall etc.). All the parameter adjustments are sensitive and make a differencs.. The speaker sim is a true thing of beauty. After all they are just eq curves anyway. These two controls allow you to dial in what works in the mix without being distracted by loading impulses. Tonight ill try it out on bass. I can definitley see where it can be used on anything really. Great job.
If I could add anything to it. It would be the spring reverb from Flextron.
