01Onboard Big Fuzz (Mustang LT25 Stomp block)
Built-in modeling block — recreates the Op-Amp Big Muff wall of fuzz
02Onboard Phaser (Mustang LT25 Mod block)
Built-in modeling block placed pre-delay/reverb to replicate the subtle MXR Phase 100 sweep
The Mustang LT25 achieves this signature sound entirely in-the-box by cascading its onboard Big Fuzz model into the British-voiced Rock 2000 amp model. Setting the humbucker on your Pacifica 112V to the bridge position supplies the hot, full-bodied signal needed to drive the fuzz model into massive Siamese Dream saturation. Keep presence null since the LT25 faceplate lacks this physical control, and dial the amp treble down slightly to prevent digital harshness from the fuzz block. Clean intro: bypass the Big Fuzz block and switch your guitar to the neck single coil.
