You can capture the highly sought-after boutique Californian high-gain guitar sounds for free using the LeXTAC amp simulator plugin created by LePou Plugins.
This legendary freeware plugin emulates the multichannel architecture, touch sensitivity, and rich harmonic overdrive of the Bogner Ecstasy—a staple high-end tube amplifier known for its thick, liquid lead lines and massive rhythm crunch. The Essential Signal Chain
To get the best high-gain sound from LeXTAC, you cannot run the plugin alone. It simulates only the guitar preamplifier and power amplifier sections. You must build this specific chain inside your Digital Audio Workstation (DAW):
The Guitar Input: Plug your guitar into an audio interface instrument input. Ensure your input levels do not clip.
The Overdrive Pedal (Optional but Recommended): Use a free tube-screamer style plugin (like the TSE Audio X30 or Ignite Amps TS-999) before the amp simulator. Keep the pedal’s drive low, but max out its output volume to tighten up the bass. The Preamp Plugin: Load the LePou LeXTAC.
The Cabinet Impulse Response (IR) Loader: Load a free IR loader like LeCab2 or Ignite Amps NadIR directly after LeXTAC.
The Speaker Cabinet IR: Load a high-quality free speaker impulse response. For a true boutique Californian sound, use an IR of a Mesa/Boogie or Bogner 4×12 cabinet loaded with Celestion Vintage 30 speakers. Dialing in High-Gain Tones on LeXTAC
LeXTAC features three channels: Yellow (Clean), Blue (Crunch), and Red (High-Gain Lead). For boutique, heavy rhythm and solo tones, switch to the Blue or Red channels using the interface buttons.
Use the following specialized parameters to shape your sound:
[ PRE EQ ] [ GAIN BOOST ] [ STRUCTURE ] PLEXI MODE 1. Modern Californian Rhythm Crunch (Blue Channel)
The Blue channel delivers an incredibly articulate, mid-forward classic boutique crunch. LeXTAC – new LePou amp! – Effects Forum – KVR Audio
