analog technology called NATURAL RESONANCE, we have been able to achieve the
feel and not just the frequency response of the classic speakers and cabinets used
today and in the past. Real cabinet resonance at all levels and driver compression at
high levels adds an organic depth and focus to your guitar tone.
We have focused on the two extremes of speakers, the alnico (Jensen) and the
ceramic (Celestion and Eminence) by providing a VINTAGE / MODERN switch. You
have a choice of 10-inch and 12-inch drivers for bottom response and mid-range
coloration by using the 10-INCH / 12-INCH switch. You can select an open-back
cabinet or a sealed cabinet with the OPEN-BACK / SEALED switch. This feature sets
the GCS-2 apart from other cabinet simulators due to the NATURAL RESONANCE
filters at the low-end that resonate or "ring" like a real sealed cabinet. Finally we have
added a MIC POSITION potentiometer to allow you to tailor the low and high
frequencies of a real speaker in the same way a sound engineer would by moving a
microphone near the edge or the center of the speaker positioning the mic. As
recording engineers will tell you, the microphone placement is the key to achieving the
right tonal spectrum for a given track and can make or break the quality of your solos
and chording.
