To better clarify; For those who may be thinking that we simply add more gain to the existing gain structure of a Rectifier series, let me assure you that is less an accurate. We first strip back what we call the fuzzy/buzzy gain (the layer that tends to mask/hide a lot of the nuances) and this is done bring more articulation and definition to the gain tones (IE: so all the nuances can come through). With that in mind we then add more gain back to the amp while at the same time balancing out the over all frequency response as well as retaining the articulation. As a result the amp is much smoother or more fluid/liquid like to play with improved note articulation. Given the audible differences it is also a feel thing, which can be difficult to record in a sound clip. We tend to hear it on recordings from many pro players because they appear to make their way up and down the fret board with little effort. It's difficult at best to try and take what you hear as well what you feel, and put that into a verbal description.
Overdrive/boost pedals; When engaged most tend to have a low end roll off thereby affectively helping to tighten up the excess/flabby low end on the amp (through rolling it off). For some this is all that is required to tighten up a Rectifier model and for others it may not work well at all so they seek other alternatives such as modding their amp.
I'm not trying to sway anyone's opinion and nor do I wish to take part in any kind of flame war but rather just trying to clarify what we do in the hopes that it will more sense to those who may be reading but not posting.
Have great guys!
