can also be connected to the INPUT of the GCS-3 when the -30dB INPUT PAD is
switched out.
The GCS-3’s HEADPHONE output has a VOLUME control so you can listen to the
cabinet simulation in total isolation. Be sure to USE ONLY STEREO HEADPHONSES
rated at no less than 25 ohms impedance to ensure proper performance. Headphones
with impedances ranging from 32 ohms to 600 ohms work best.
To achieve great, consistent tone from a wide range of signal sources, including effects
pedals, preamps, combos or heads to a recorder or house sound system, simply insert
the GCS-3 in the signal path coming from anyone of these sources. For example,
when using a combo or a head, insert the GCS-3 between the power amp output and
the speaker cabinet. You will need an extra mono speaker cord with ¼” phone plugs
on each end. Be sure to set the -30dB INPUT PAD switch to “IN,” so the signals will
not over load the GCS-3.
Another way to feed your guitar signal from a combo or head amp, is to take the signal
BEFORE is feeds the power amp stage. This is typically the “PREAMP OUTPUT” jack
on the back of the amp. If there is no PREAMP OUT, then try the “SEND” jack of an
effects loop, if you have that available on your amp. In either case you can still have
the preamp out signal available from the THRU jack on the GCS-3. This is because
the THRU jack is hardwired to the INPUT jack of the GCS-3.
