    controls you can achieve everything from a scooped metal sound to a vintage style hard rock sound. Quite a lot gain is available here, perfect for solo parts indeed. - CH2: the most brutal hi-gain sound available from our catalog. This is something almost insane for our standard but at the end of the day, lots of music genres use this quantity of saturation.

Now youʼre ready to put the Power Switch in “POWER ON” position.
Leave the amplifier in this state for at least thirty seconds. Plug your signal cable into input jack and youʼre ready to put the Standby Switch in “ON” position.
  • Page 11 Leviathan, despite the full tube audio signal path, is equipped with a digital memory which can save combinations (preset) inside the amp.
Duality is shipped with a presetted midi channel #1. You canʼt change midi channel on the fly after you have bought it, but you can ask us for a different midi channel at order time.

    LOOP FX Loop effects on Leviathan is between the preamp output and the power amp input, right before the master volume. Itʼs a buffered 100% serial loop fx with instrument level signal.
When loop effect is engaged 100% of your sound will pass thru the effect wired to send/return jacks.
  • Page 13 L120F FOOTSWITCH Leviathan comes with L120F footswitch. It can operate only with the L120 model. L120F canʼt be used with other amplifiers or devices, since it can be damaged by incorrect use.
L120F can basically do all the same things as the player can do with tactile buttons situated on the front panel.
  • Page 14 TUBE LAYOUT This amplifier comes with KT88 type tubes in the power amp section and 12AX7B in preamp, selected trusty partners Tube Doctor. Power tube can’t be changed with other type of tubes (i.e 6L6s, El34s, etc), they can be substitute only with other KT88 type tubes. You need to check the bias every time poweramp tubes are changed.

    CABINET AND SPEAKERS For the best sonic experience ever we highly suggest to play this amplifier with RedSeven Pro Cab series, especially with 4x12 model. We develop this amplifier thru this cabinet so this is the natural extension for it. We suggest you to try L120 with Celestion V30.This is our first choice.

    to blown, turn off the amp and contact RedSeven Amplificaton. • L120 IS TURNING ON (RED LED IS ON) BUT WITH NO SOUND First of all be sure to connect speaker cable properly, both amplifier as the cabinet. Check the input signal from guitar too. If this doesn’t work check HT fuse, if it’s blown replace with SAME type and try again to turn on again.
  • Page 17 This amplifier runs at very high voltage that can lead to death. Any inexpert person should not even think of do anything inside this amplifier. RedSeven Amplification offer a standard two year fully warranty for any component (except wear subjects).
