The GP-100 provides precise reproductions of many of the guitar amps that have achieved status as classics. It provides not just a simulation of distortion and speaker response, but a comprehensive emulation that reproduces the unique tonal changes, nu-ances, andeven the ways in which interference might be produced as a result of the placement of various pieces of equipment in the setup — all based on an exhaustive analysis of the electronic parts and circuits that were actually used in the original guitar amps. Simple operations allow you to select a desired type of guitar amp, and you can adjust gain, volume and the various tone controls to create the perfect sound for your system. Analog-Feel Controls Guitar preamp operation features an "analog feei." The knobs on the front panel provide immediate and intuitive control. Speaker Simulator Function The built-in speaker simulator function not only provides the choice of stack, built-in, and compact amplifier types, but also lets you control the mic placement - making it a powerful ally for direct-line recording High-Quality Signal Processor
The GP-100 also includes a professional quality signal processor designed especially for guitar. It provides compressor, wah, cho-rus, delay, reverb, and even a pitch shifter with "Harmonist" (intelligent pitch shifting). With the signal processor and preamp working together, the GP-100 is all you need to create and perfect your guitar sound.
FullRange of Connectorsfor Flexibility Two sets of programmable send/return jacks are provided, and you can freely specify their location in the signal path. Two pairs of programmable stereo outputs are also provided. In addition, the two external control jacks allow external devices to be turned on/off etc. Rich Array of Control Functions A total of 400 settings (200 Preset and 200 User) can be stored as Patches. Patch settings can be recalled instantly using the front panel knob or by MIDI program changes. Control assign settings allow you to have realtime control over a maximum of 16 parameters. An FC-200 MIDI Foot Controller (optional) can be connected to control the GP-100 via foot pedal.
IMPORTANT NOTES In addition to the items listed under Safety Precautions inside the front cover, please read and observe the following: (Power Supply) • Before connecting this unit to other devices, turn off the power to all units; this will help prevent damage or malfunction. • Do not use this unit on the same power circuit with any device that will generate line noise; an electric motor or variable lighting system for example. (Placement) • Using the unit near power amplifiers for other equipment containing large poor transformers) may induce hum. • This device may interfere with radio and television reception. Do not use this device in the vicinity of such receivers. (Maintenance) • For everyday cleaning wipe the unit with a soft, dry cloth or one that has been slightly dampened. with water. To remove stubborn dirt, use a mild, non-abrasive detergend. Afterwards, be sure to wipe the unit thoroughly with a soft, dry cloth. • Never use benzene, thinners, alcohol or solvents of any kind, to avoid the possibility of discoloration and/or deformation. (Additional Precautions) • Protect the unit from strong impact. • Never strike or apply strong pressure to the display. • A small amount of heat will radiate from the unit during normal operation. • Before using the unit in a foreign country, consult with qualified service personnel. (Memory Backup) • The unit contains a battery which powers the unit's memory circuits while the main (AC) poweris off. The expected life of this battery is 3 years or more. However, to avoid the untimely foss of memory data, it is strongly recommended that you change the battery every 3 years. Please be aware that the actual life of the battery will depend on the physical environment - especially the temperature - in which the unit is used. When it is time to change the battery, consult with qualified service personnel. • When the battery becomes weak, the following message will appear in the display. Please change the battery as soon as possible to avoid the loss of memory data. Battery Low Please Change
