Modern music forces guitar players to apply various electric guitar effects.
In consequence, a lot of players have a collection of different equipment: pedal effects (stomp box) - single or multi ones, pre-amps, amps, etc.
The necessity to switch between various effects appears not only between different songs played but also during a particular song. Switching between effects and adjusting their proper settings (collectively called presets) is relatively difficult to operate (necessity to press several footswitches and/or to turn the knobs and press switches or buttons at the same time).
After some time the problem of switching and setting effects limits the performance and creative capacities (it is useless to create performances which can't be realised).
The Guitar System Controller is an analog device designed to enable easy selection of a preset from the wide range of offered ones by pressing just a single footswitch. At the same time the GSC improves the comfort of use and sound quality. The GSC enables the further development of a guitar system.

Basic characteristics:

 

  • high impedance input (identical with a tube amp characteristics) based on FET transistor
  • independent guitar’s TUNER output with the silent tuning function
  • four loops for connecting single effect pedals (stomp boxes) or serially connected stomp boxes) with skipping (relay bypassing) switched off effects
  • four outputs 9V DC supplying effect pedals (totally max. 160 mA with overloading indication)
  • volume change module (full or lowered defined by the analog knob) to apply in the solo/background playing mode
  • 2 outputs (2 lines each, latching type) for amp's switching by footswitch input
  • MIDI output setting the program No. of e.g. an effects’ processor (giving possibility to control independently two MIDI units by one of their THRU outputs)
  • 5 footswitches to select presets (6 banks with 5 presets each)
  • 1 footswitch with a definable function (choice: loops direct switching mode, switching to the previous bank, changing the volume or MUTE)
  • very silent footswitches (backlighted)
  • LINK connector for connecting the second GSC device to form a set with double possibilities (working in two modes: "remote" or "nearby")
  • a possibility to connect a wah-wah effect pad (wah-pad) to control the system by placing foot on it
  • the main signal output giving possibility to connect parallely several amps using a long cable (10 meters) without signal quality loss
  • massive powder coated casing and durable switches material
  • external power supply with a long ( 3,5 meters) and flexible cable which eliminates a power supply presence on the floor and provides increased safety level.

1. Preset selection

Press shortly (less then 1 second) the preset footswitch numbered from 1 to 5 (the selected preset’s indicator will be lit).

2. Bank selection

Press and keep (more then 1 second) the preset footswitch numbered from 1 to 5 or the DEF footswitch (bank indicators: continuos lit means A, B or C bank enabled, blinking means D, E or F bank enabled).

During switching banks adequate preset will be enabled for 1 second and later it will return to the previously selected preset.

It is recommended to program presets in banks in such a way that all necessary presets used in a particular song will be located into just one bank or it is recommended to use DEF footswitch for switching between latest used banks.

3-1. Silent tuning (MUTE)

a) Press at the same time preset footswitch No. 1 and No. 2 (all presets’ indicators will start to blink).

b) To exit from MUTE press the preset footswitch intended to be used.

3-2. Silent tuning (usage of DEF footswitch)

a) In case of using DEF footswitch as a silent tuning one (see: LOOP button settings) press DEF footswitch.

b) To exit from MUTE press the preset footswitch intended to be used or DEF footswitch again (it will return to the previous preset).

4. Loops direct switching mode

DEF footswitch is set as the loop direct mode switch (see: LOOP button settings). In this video the preset was selected previously.
a) Press shortly DEF footswitch (preset indicator starts to blink and LOOP indicator starts to light).

 

b) Following pressing any preset footswitch will effect in consequent enabling and disabling (toggling) loops numbered from 1 to 4 and the volume change.

 

c) Press DEF footswitch to return from the loops direct switching mode (preset indicator starts to light and LOOP indicator stops to light).

5. Loop (LOOP1 to LOOP4) and volume programming

a) Select the bank and the preset.

 

b) Memory access lock switch to UNLOCK position (LOCK indicator not lit).

 

c) Press LOOP button (LOOP and preset indicators start to blink).

 

d) By presets footswitches set loops (effects) which should be active (if any of LOOP1 to LOOP4 indicators lit mean these effects are activated). Set volume by No. 5 preset footswitch: not lit VOLUME indicator means full volume and lit one means volume definable by position of the knob.

 

e) Press LOOP button to save. Quick blinking of LOOP and selected preset indicators confirm saving.

 

REMARK:
In case of not plugging in a connector to a particular effect’s loop RETURN the signal will skip such a loop despite of activating this loop. It allows to use presets despite of not connecting effects to such a loop.

6. Amp settings programming

a) Select bank and preset.

 

b) Memory access lock switch to UNLOCK position (LOCK indicator not lit).

 

c) Press SWITCH button (SWITCH and preset indicators start to blink).

 

d) By presets footswitches set the selected amp settings (active channel and/or reverb on/off). SW1 to SW4 indicators signalise amp settings.

 

e) Press SWITCH button to save. Quick blinking of SWITCH and selected preset indicators confirm saving.

7. Preset’s copying

a) Select preset to copy.

 

b) Memory access lock switch to UNLOCK position (LOCK indicator not lit).

 

c) Press at the same time LOOP and MIDI buttons (LOOP, SWITCH and MIDI indicators will start to blink).

 

d) Switch bank (if necessary) and choose preset No. where to copy selected preset.

 

e) Press at the same time LOOP and MIDI buttons to save preset. Successive quick blinking of LOOP, SWITCH and MIDI indicators confirm saving.

8. LOOP button settings

a) Memory access lock switch to LOCK position (pressed, LOCK indicator lit).

 

b) Press and keep LOOP button then memory access lock switch to UNLOCK position (LOCK indicator stops lit). All three banks’ indicators start to blink and the LOOP indicator starts to light. Presets indicators will show the current settings of the LOOP button. The meanings of these settings are shown in the below table.

 

c) Pressing presets footswitches will effect in changing of particular settings.

 

d) Pressing the LOOP button will effect in saving settings (short, mutual blinking of bank indicators confirm saving).
