THE J is the second pedal in our “Analog amp emulator” series. This concept aims to capture what you hear from an amplifiers. I’ve been friends with Jesse Hoff for years, several years ago I cheekily suggested I’d like to capture what his flagship Lazy J the “J20” sounds and feels like. To my delight Jesse agreed, and we began working our magic together. In the pedal development we made sure that the enhanced chewy tweed tones of the J20 were covered tonally but as always, we went further than the initial scope of design. Fitted with a high-quality transformer, the pedal reacts to your playing and overdrives and feels like a full-size amplifier.

THE ”J” as an Analog amp emulator can work fantastically well with your existing amp, your existing pedals and it integrates easily into your current rig. You can use it to create beautiful, enhanced tweed “LAZY J – J20” vintage amp sounds or craft your own sound. Tested worldwide during its development on the biggest of stages, you can be confident the “J” will deliver.

CONTROLS

  • LEFT FOOTSWITCH: ON/OFF. Turns the pedal on and off, true bypass.
  • RIGHT FOOTSWITCH: Switches between the Normal and Bright Channel. 
  • OUTPUT: This is the Master Volume and controls overall output.
  • RESPONSE: A subtle presence adjustment control.
  • SUPPLY: Emulates the Voltage attenuation control in the J20- Full clockwise is full voltage, anything below this emulates voltage attenuation.
  • NORMAL: Controls the volume/gain for the normal channel.
  • TONE: This allows you to dial in the EQ you’d like for the pedal, from dark to strident.
  • BRIGHT: Controls the Volume/Gain for the Bright channel.
  • X / Y SWITCH: This allows you to select what emulated input valve you want, 12AX7 for medium gain tones and 12AY7 for lower gain drive.

POWER: THE J is designed to be powered by a 9V DC centre-negative 2.1mm power supply. Internally the voltage is bumped up to 18V. Do not attempt to use this pedal with other voltages or polarities. We have power protection circuitry in our pedals and use of any other voltages will shut the pedal down and require return to ThorpyFx HQ for repair. This will not be covered under warranty.

Preamp & DI Pedals

A preamp brings an instrument signal to a controlled level and shapes its impedance, gain and frequency balance before amplification or recording. A DI converts the signal for a balanced, low-impedance connection and may include ground lift, pad and transformer isolation. Combined units can add drive, cabinet filtering, effects loops and parallel outputs while keeping the direct path stable.

Analogue

The signal is shaped by continuously varying electronic circuitry rather than being converted into a digital effect algorithm. Component choice, operating voltage and circuit tolerances influence headroom, noise, clipping texture and the small variations in response between designs.

True Bypass

Connects input directly to output through mechanical or relay switching when the effect is off, removing the active circuit from the audio path. It avoids buffer colour but leaves cable capacitance and switching design to influence high-frequency loss and possible switching noise.
