Dear Customer!
Thank you for choosing our product.
G LAB Dual Reverb DR-3 (DR-2) is an analog-digital reverb type stompbox.
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
- 9V DC power supply.

Diagrams of connecting
In case when you use only stompbox overdrives the DR should be connected as
the last stompbox pre amp.
When you use overdrive channel (or channels) of your amp the DR should be
connected at the and of the signal path what means, to the amp effect loop.
4
If your amp is equipped with SEND output signal level control then you should set
the active reverb LEVEL control to maximum and set in a such way your amp SEND
output signal level control to be at the edge of lighting up the DR PEAK indicator (it is
recommended to set the amp channels controls at typically used positions and to check
all the channels). Then you should adjust RETURN input gain control to receive the
same signal level (volume) when the effect loop is active or not.

Control settings
The REVERB 1 or 2 switch enables to select sound characteristics of the used reverb.
TIME controls enable adjusting the reverb time from hundreds of milliseconds up to few
seconds (REVERB 2 offers longer lasting sounding). LEVEL controls enable adjusting the
proportion of the resounded from zero signal to the level of 25% of the incoming one.
Thanks ability of setting two pairs of reverbs time and level parameters, and also thanks
footswitching between these two pairs (REVERB A and B) it is possible switching the used
reverb while playing, what reasonably increases a guitar tone performances.
Typical controls settings:
- quick support playing: REVERB = 2, TIME = 1 to 2, LEVEL = 3 to 5,
- slow support playing: REVERB = 2, TIME = 2 to 4, LEVEL = 4,
- solo: REVERB = 2, TIME = 3 to 5, LEVEL = 4 to 6.
Power supply
The DR should be supplied from external regulated 9V DC power supply, with 80 mA
output or more. Before connecting please check if the connector’s polarisation is proper.
REMARK: Damage of the DR caused by supplying it with power of improper
voltage effects in loss of the warranty.

Connecting to the GSC (Guitar System Controller)
The DR can be controlled and supplied form the GSC controllers of the G LAB
brand. In such a case the SW1&2 (or SW3&4) output of the GSC connect with the DR
FOOT PEDAL input by a Jack/Jack mono cable.
According to the signal (only in case when we don’t use the amp’s reverb) it is
recommended to connect the DR between the GSC and the amp input.
