Laney Lionheart L20T-112 combo guitar amp 20W All-tube 12" Parallel Single-Ended Class 'A' Amplifier Made in UK

PARALLEL SINGLE ENDED
Designed, engineered & made with pride in Great Britain. The Lionheart L20T-112 is a 20 watt Parallel, Single-Ended, Class 'A' all-tube combo, giving a great range of clean, crisp, dynamic and open guitar tones. With less emphasis on preamp distortion, the L20T-112 lets you hear more of you the player and your guitar and feel the power tubes clipping to breakup, giving a much richer harmonic content and a larger dynamic range than many other amps. Whatever your style, play through a Lionheart and you’ll be amazed at how it reacts to your touch.

DETAILS
From a guitarist point of view, in a class A amplifier each of the amplifiers power tubes are working at maximum output the whole time. This makes them run ‘HOT’ and generates a very natural level of smooth tube compression.

Higher powers are obtainable by using multiple valves in parallel – in this case 4 x EL84’s are run in Single ended mode and then paralleled up to give 20 watts RMS of Parallel Single Ended tone.

FX loops are important as they allow you to add effects to the signal path in a specific place between the pre-amp and the output section on an amplifier. This is where FX loops are important as it allows you to put time-based FX after the distorted pre-amp section. For example, delayed distortion sounds different to distorted delay – try it.

The G12H guitar speaker is hugely popular with players looking to recreate the classic sounds of 60s and 70s rock. With a strong, aggressive low-end and powerful low-mids, the G12H penetrates any mix with an attacking upper mid-range and an ice-cool top- end.

On-board studio quality reverb. Reverb gives you a sense of the space that you are in. A dry guitar signal can sound a little dull. Adding the right about of reverb provides the guitar signal with ambience and brings it to life.

Designed, engineered and built with pride in Great Britain.
The Lionheart range brings boutique Single-Ended & Parallel Single-Ended Class ‘A’ tube tone to the discerning player who is looking for uniquely responsive BRITISH tube tone.
The Dark Art: In an age where guitar players have developed an unhealthy fascination with pre-amp distortion, the fabled sound of a tube power amp being pushed hard has almost passed into history.
Until now that is!
The 20W Parallel Class A Single Ended output stage installed in the L20T-112 and L20T-212 oozes classic, warm tube tones: The harder you drive it, the better it sounds. Plus with enough gain for contemporary tones, it also has a mean, spiteful side to it as well – making it ideal for any style of playing. Perfect for stage and studio use.
Every Lionheart product is extensively play tested by experienced guitarists before being shipped to our customers. Only when the unit is finished to our complete satisfaction is it assigned its own unique build number which is then hand stamped onto the rear mounted plaque.
Your L20T should give you years of trouble-free amplification, however please take time to read this manual and familiarise yourself with the controls as it will allow you to get the best from your amplifier.
We hope you enjoy using your L20T as much as we enjoyed designing and making it.

WHAT'S IN THE BOX?

• Slip cover
• Main power supply lead

1 - HI INPUT: ‘Hi’ stands for high gain. This input is designed for the connection of low output level guitars making it well suited for guitars with single coiled or low gain hum bucker type pickups. Use of high gain pickups in this input may drive the preamp too hard causing a “mushy” sound. Only use good quality guitar cable.
2 - LO INPUT: ‘Lo’ stands for low gain. This input is attenuated down approximately 50% from the Hi input and is designed for high output level guitars. It is useful in obtaining output that is “tight” not “mushy” from high gain humbucker type pickups. Also use this input for the cleanest full range sound with extended low end response. Only use good quality guitar cable.
3 - CLEAN VOLUME: Sets how loud the clean channel is. Try cranking it up a little to drive the power tubes harder for that real retro sound and feel that only a quality tube amplifier can deliver. Now use your guitar volume to control the amount of distortion. (Wind it up for distortion back it off a little for clean).
4 - BRIGHT: Adds brightness and life to the treble frequencies of your guitar when on the clean channel. Adds edge and picking emphasis when on the drive channel. The switch has more effect at low Clean Volume/Drive control settings. Use in conjunction with the Treble and Tone controls for optimum performance. Switch up to enable.
5 -
DRIVE: Sets the level of tube preamplifier drive or how dirty your sound is. This control should be used in conjunction with the Drive Volume (6) Setting low levels of gain with high levels of volume will give a clean preamplifier sound with tube output stage overdrive.
Setting a medium drive level and medium Drive Volume will give a nice crisp bluesy lead tone, again with the ability to drive the output stage at higher Drive Volume settings. Setting a high level on the Drive control and a low setting on the Drive Volume will give you a punchy hard rock lead tone, with the ability to again drive the output tubes at higher Drive volume settings. Having set the Drive and Drive Volume controls to your desired sound try backing off your guitar volume and tone controls for lots of other cool sounds. Good tube amplifiers have the unique ability to produce a wide range of sounds by using only your guitar controls, playing weight and style.
6 -
DRIVE VOLUME: Sets how loud the ‘Drive’ channel is. It is useful to experiment with drive levels and drive volumes. If you want a very open, warm and semi overdriven sound try reducing the amount of drive and increasing the drive volume. This reduces pre-amp gain
but pushes the power amp section and makes it work harder giving you a very desirable level of power amp distortion which is a very pleasing “retro” style sound.
7 -
DRIVE SWITCH: Switch up to enable the ‘Drive’ channel. (This switch must be in the down (OFF) position in order for the drive to be switched remotely via a foot switch.)
8 -
DRIVE LED: This LED will illuminate when the Drive channel is activated with the Drive switch (8) or the included Laney FS2-MINI remote footswitch.
9 -
BASS, MIDDLE, TREBLE: These are a traditional set of passive tone controls. Passive controls have the advantage of always sounding musical at any of their settings mainly due to their unique interactive nature. This gives players a more natural set of tools to create
their ideal sound. (Try them all set at midway (5) as a good starting point).
10 - REVERB: Controls how loud the built in reverb sounds.
11 - TONE: The tone control works in a similar fashion to the Tone control you probably have on your guitar except that it uniquely works at the other end of the amplification chain. This has the ability to not only control the overall top end response but also reduce upper end harmonics on the output stage and preamplifier overdrive sounds. This will give you bright cutting sounds at high settings and smooth rounded sounds at lower settings. (Midway (5) is a good starting point).
12 - STANDBY SWITCH: Disconnects the main HT voltage from the tubes but keeps the tubes warm so that they are ready to go instantly. Switch to standby for short breaks when you don’t want to wait for the tubes to warm up again.
13 - POWER LED: This LED will be lit when the amplifier is switched on. (Always switch off and disconnect the power cord when not in use).
14- POWER INLET SOCKET: Connect to your power source. Make sure the specified voltage is correct for your country!
15 - POWER FUSE: This drawer contains the main safety fuse for the unit. The fuse protects the AC power to the amplifier. USE ONLY THE CORRECT SIZE AND RATING OF FUSE AS SPECIFIED ON THE PANEL. If a fuse blows or fails and a replacement of the same size and rating is installed and it in turn blows, the amplifier has suffered a malfunction internally and needs immediate service from a qualified technician. DO NOT TRY USING A FUSE OF HIGHER RATING. Using a fuse that is too large in current rating may cause serious, irreparable damage to the amplifier and presents a serious fire hazard. The mains fuse rat- ings are detailed in the specs section at the rear of this manual
16 - POWER: Main power switch for unit.
17 - HT FUSE: This fuse protects the DC power to the tubes within the amplifier. USE ONLY THE CORRECT SIZE AND RATING FUSE AS SPECIFIED ON THE PANEL. If a fuse blows
or fails and a replacement of the same size and rating is installed and it in turn blows, the amplifier has suffered a malfunction, at this point check the output tubes and replace faulty ones if required. Should tubes not be the problem the amplifier should be checked out by a qualified technician. Do not try using a fuse of greater value. Using a fuse that is too large in current rating may cause serious, irreparable damage to the amplifier. Fuses are designed to protect, do not take chances.
18 - EXTENSION CABINET: Use to connect an 8-16 ohm extension cabinet. Please note mismatched impedance will reduce the amplifiers performance and in some cases may cause damage to your amplifier. Set the switch to the 8 ohm when using only the internal loudspeaker, switch to the 4 ohm setting when connecting to an additional 8 ohm cabinet. Try the L20T-112 into a Laney Lionheart LT212 cabinet - you will be amazed what this little baby cranks out. Note: If the onboard loudspeaker jack is removed, an 8 ohm cabinet can be connected directly to the 8 ohm socket.
19- FX-LOOP:
FX RETURN: Mono jack socket for the connection of the output of an external FX unit. This can also be used as a slave in for the power amp. As the FX loop is an insert type, this will mute the preamp.
FXLOOP SWITCH: Selects the FX loop mode of operation
• 10 dBu - For connection of FX units with a -10dBu nominal output level. As this is intended for devices wth a lower output level, this switch increases the gain from the FX loop by 10dBu.
• 0 dBu - For connection of FX units with a 0 dbu nominal output level.
• Bypass - Removes the FX loop from the signal path.
FX SEND: Mono jack socket for connection to the input of an external FX unit.
20 - FOOTSWITCH SOCKET: Provided for connection of the included Laney FS2-MINI footswitch. This allows you to remotely switch between the clean/drive channel and switch the built in reverb On/Off.
