IMPORTANT NOTE - Effectrode pedals comes with a 12V centre positive (+) power supply with Australian power plug. Using a wrong power supply causes a permanent damage to the pedal and won't be covered by the warranty. Polarity Converter sold separately if wanted to integrate with exisiting power supply that has 12V centre negative output.

\nThe EffectrodeŸ âLA-1Aâ Leveling Amplifier was designed with one purpose in mind: to enable artists and engineers extract every last nuance from a musical performance⊠without compromise. Tubes are unmatched tone enhancers, adding warmth, depth and clarity to recorded and live instruments and Effectrode wanted to push their sonic performance even further and beyond expectation. To that end we based our Leveling Amplifier on a parallel tube plate designâthe type of tube circuitry only found in audiophile tube phono-stage preamps for high-end turntables. Parallel tube design reduces the LA-1Aâs noise floor to vanishing point. In practical terms this means best possible signal to noise ratio for your guitar. Itâs an expensive way of doing thingsâas four identical tube input stages are used in its circuitryâbut it does yield stellar sound quality, without the compromise of noise gates or âcuttingâ certain frequencies using equalisation. The parallel tube design has never been built into a stompbox or even a professional studio leveling amplifier/compressor before, making the LA-1A a truly special compressor.
\nFEATURES
\n- \n
- Peak Reduction knob sets both the threshold and the amount of signal compression. When adjusting the compression or sustain a good starting point is the 9 oâclock position where subtle leveling enhances note detail, creating a fuller, warmer tone. As the knob is rotated clockwise the volume level of loud notes is reduced relative to quieter ones, squashing playing dynamicsâthe definitive sound of many country and funk-style guitar riffs. \n
- Gain knob adjusts the âmake-upâ gain and is used to match the relative levels of bypassed and effected signal. It can also provide +15dBu of tube boost when the âPeak Reductionâ knob fully counterclockwise (zero compression). \n
- Boost knob gives an additional +6dB of gain (on top of the make up gain)âuseful when soloing on guitar or bass and can push the input stage of a tube amp into overdrive very nicely too. The âBoostâ footswitch engages (red LED lit) and bypasses (green LED lit) the boost. \n
- Attack and Knee knobs allow the compression character to be tailored perfectly to suit instruments that are challenging to amplify or record. For example, active 5-string bass guitars, nylon and steel string acoustic guitars fitted with piezo pickups and even especially âdifficultâ stringed instruments such as hammered dulcimer, harpsichord or tar. Rotating the âAttackâ knob clockwise increases how fast the side-chain reacts, i.e. the speed at which compression kicks in. The âKneeâ knob alters the input/output curve, i.e. how the LA-1A transitions into compressionârotate clockwise and the LA-1A becomes a limiter and counter-clockwise for compression. \n
- When the Dynamic EQ toggle switch is in the âdownâ position the LA-1A dynamically boosts high frequency material. With the âPeak Reductionâ knob fully counter-clockwise (zero compression) dynamic eq is inactive, however as the knob is rotated clockwise, and the pedal begins compressing, the effect becomes increasingly pronounced. Fabulous for jangly 12-string RickenbackerŸ guitar sounds. \n
- Bypass Footswitch utilises quiet true bypass switching to minimise âpopsâ or âthumpâ when engaging the pedal and ensure there is no loss of guitar tone when the pedal is bypassed. \n
- Balanced Direct Out ÂŒâ TRS (stereo) jack socket allows connection of the LA-1A to mixing desk, computer sound-card or external audio capture device. This output is fully balanced and transformer isolated, eliminating earth loops and reducing hum to an absolute minimum and features a gain pad (+6dB, +12dB and +18dB) to facilitate matching with any line or instrument level gear. The Triad Magnetics audio transformer also imparts itâs own character to enhance and sweeten the direct sound. \n
- External Select ÂŒâ TRS (stereo) jack socket. This enables an external footswitch, such as the FenderŸ âTwin Reverbâ Amp tremolo/reverb dual latching footswitch), to be utilised for remote bypass switching and activating the tube boost. \n
