Generally speaking good copy; a few pages too hard contrast...
Good service and communication.

I purchased the unit from a private party and the original owners manual was not available. Having the ability to download it was extremely helpful and clarified operating the equipment immensely. This is a complicated unit and without the manual I would not have been able to maximize it's potential. Thank you.

Being a user of older radios of many kinds, preferring them over more modern rigs, this manual was invaluable in the programming of my two. I now know for certain what the assorted buttons functions are, and am very grateful to have found this excellent site. Many thanks for your assistance, Tony.

Quick response and exactly what I was looking for and at a great fair price!
700RB Series Sound Tips
The 700RB Series has several unique features which, if used properly, will obtain that sound you have been searching for.
The Equalizer:
The Equalizer is used to fine tune your sound. When adjusting it, do it just a little at a time. These are active circuits, and small changes can make a big difference in your sound. With a little experimentation you will find that this equalizer is very easy to use, never sounds weird and provides you with a large variety of great sounds, unique to GK.
Boost/Master:
Turning up the Boost control, will add a little growl to your tone. This is an unmistakable GK trade mark sound, that you will grow to appreciate. Raising the Boost while lowering the Master will add more growl while keeping the sound level the same. Growl is actually a small amount of even order harmonic distortion, that sounds great through a woofer, but horrible through a horn (see Bi-Amp solution below). For most playing situations, the Master is set between 12 & 3 o�clock. The cleanest sound is obtained by setting the Master above 12 o�clock, and going above 3 o�clock for maximum power situations.
Sound Tips
Contour:
Increasing the Contour level will scoop out mid-range frequencies while boosting the highs and lows. The sound, once again, is unique to GK and unavailable on any other Bass amp.
String Bass:
The way a Bass amp deals with the instrument low string is a critical part of its sound. In fact, a five string instrument requires an entirely different low end response than a four string instrument. No equalizer can make the necessary adjustments to accommodate both. However, the String Bass button on the 700RB Series does just that. When it is out, the 700RB is voiced like the 800RB (the world�s classic four string amp). Push it in and the 700RB is voiced for five string instruments. For some playing styles you may want it in, even with a four string instrument.
Direct Out:
The 700RB provides a low noise, high quality balanced direct out for connection to PA and recording consoles. With the Pre/Post EQ switch set to �Pre� (Out), the direct output signal is fed directly from our low noise, high headroom, FET input stage providing a low noise output superior to external direct boxes and impedance transformers. In addition, this output is calibrated for 1.0V (0 dBV) output and can be adjusted to unity gain (instrument level) by adjusting the Level control to -15 dB (U) . With the switch in the Pre position, the Direct Output signal is only effected by the Level, -10dB Pad, and Tuning Mute controls. This allows you to adjust your tone and volume on stage without changing the Direct Output signal level and confusing your sound man. Changing the Pre/Post EQ switch to �Post� ( In), sends the �GK sound� and preamp response to the Direct Out jack. This gives you complete control over the Direct Out�s tone and volume. In addition, a Ground (Gnd) Lift switch is included to remove hum and buzz when connecting to equipment powered by a different ground system.
