Thank for the quick reply Mike.
One of the main reasons for me (about) to purchase an amp sim like Scuffham S-Gear, is the cost savings (& convenience) over real world physical amps/fx. A couple of years ago, i bought a lovely marshall combo, but wait, I want a delay, but wait, I need a chorus pedal, oh hang on, I need a tremolo....that all starts mounting up. An amp sim typically has them all in one simple onscreen interface.
Just my bit of pre-sales feedback for you ...I think a decent tremolo should be available across all amp models, so please consider releasing a tremolo pedal soon
