Dual Reverb DR-3

Product code 00860


Dual Reverb DR-3 is an analog-digital stompbox which adds some deepness and space to your guitar tone. DR-3 makes you feel like playing in the real room with many reverberations. You can switch between two sets (A and B) of the reverb time and intensity. The MAX ANALOG technology and the optical true bypass assure the best sound quality and smooth ON/OFF switching (sustaining previously played tones).

DR-3 is constructed according to mostly used by guitarists parameters. There were chosen in it the adequate ranges of reverb time and intensity.

Similarly to other G LAB devices the DR-3 combine the effect functions with the enlarged possibilities of control. Two types of reverb (1, 2) features various resounding time characteristics and a little different tonality. Dual Reverb DR-3 is very simple in use and will not make any problems even for the beginners.


Basic characteristics:

  • two reverb types (REVERB 1 or 2) with various sound characteristics,
  • two sets (A and B) of reverb time and effect intensity controls,
  • effect ON/OFF footswitch,
  • A or B parameters selection footswitch,
  • smooth ON/OFF and parameters switching (not cutting sounding of previously played tones),
  • signal overdrive indicator (PEAK),
  • high level of maximal signal (8 dBu) what enables to use it at amps effect loops,
  • silent switching and low noise level,
  • FOOT PEDAL input for controlling it by a guitar controller e.g. G LAB GSC,
  • metal footswitches with backlighted descriptions,
  • solid, powder coated casing,
  • 9V DC power supply.

Connecting to the amp guitar input

In case when you use only stompbox overdrives the DR-3 should be connected as the last stompbox before an amp.

Connecting to the amp effects loop input

DR-3 should be connected at the end of the signal path, before an amplifier. It means that when we use an overdrive channel (or channels) of an amp the DR-3 should be connected to the amp effect loop.

Connection to the Guitar System Controller (GSC)

The DR-3 can be controlled and supplied form the GSC controllers of the G LAB brand. In such a case connect the SW1&2 (or SW3&4) output of the GSC with the DR-3 FOOT PEDAL input by a Jack or MONO Jack cable. In case when we don’t use the amp’s overdrive it is recommended to connect the DR-3 between the GSC and the amp input. The power supply can be supplied then from 9V output of the GSC.
