R&R SL/LD MultiGain PRE-AMPLIFIER. OVERVIEW
1-2 R&R SOUND AMPLIFICATION SL/LD MultiGain PRE-AMPLIFIER
MANUAL
The SL/LD MultiGain model 3-channel guitar preamp is designed with five 12AX7 tubes. It has a rack design (1 unit high) and
is convenient for use both in the studio and in concert activities, easy to use. It has a wide range of sound adjustment that
allows everyone to find their own unique sound.
џall-tube sound path (5 tubes 12AX7) with the ability to use tubes from different manufacturers separately for clean and
overdrive sound;
џ3 completely independent channels: CH-1 CLEAN (clean channel), CH-2 LEAD 1 (overdrive channel) and CH-3 LEAD 2
(drive channel). Channel switching is carried out both on the front panel and from the 2-button foot controller that comes
with the preamplifier;
џFX LOOP tube effects loop with a choice of operating modes (serial or parallel), switching on / off separately for clean /
drive channels, control from a two-button foot controller, softening the sound of transistor and digital processing due to
the use of a 12AX7 lamp in the circuit;
џA250K / A1M mode GAIN control for channel CH-3 (LEAD-2). The A250K has a more punchy sound with more pronounced
low frequencies. A1M has balanced high and low frequencies;
џconnecting to the instrument input of a guitar amplifier (as an effects pedal), to the RETURN of a guitar amplifier, or to a
final power amplifier (as a preamp);
џbuilt-in speaker simulator for line connection and recording devices;
џdedicated headphone output.
R&R SOUND AMPLIFICATION SL/LD MultiGain PRE-AMPLIFIER
MANUAL 1-3
CH-1 CLEAN (clean channel):
The “GAIN” control plays a key role here, and at low values the sound is well suited for playing picks, drumming rhythms, etc.,
while at high values there is a “glass” - a crystal clear, transparent sound suitable for blues solos. When using powerful
humbuckers and the GAIN control close to the maximum, you can get a slight crunch. Excellent channel dynamics allows you
to highlight the solo with a simple increase in attack. There is a 3-band pre-gain EQ for fine-tuning the sound.
CH-2 LEAD-1 (overdrive channel):
Quite significantly overloads the sound. Suitable for playing blues, hard rock and heavy metal from the 70s and 80s. Works
well in other styles that don't require hi-gain overdrive. Transparent, warm, overtone-rich sound, harmonics “shoot” from
under the fingers even at low levels of the GAIN control. The BRIGHT switch will add "glass" to your solos, and the rhythm will
sound sharper. The presence of a 3-band post-gain EQ and a PRESENCE control allow you to create a wide palette of sounds.
CH-3 LEAD-2 (drive channel):
Very dense, aggressive, heavy and fat HI-GAIN overdrive - "that" Californian sound. The stock of gain is incredible. The
warmth and compression of the tube is excellent. The sound is very versatile and is well suited for both GARY MOORE's
stringy solos and the tight rhythm of the heaviest styles. Good readability in low tunings. There is a 3-band EQ located after
the gain. The PRESENCE control will make your part stand out in the mix.
