Jaded Faith Mods is a New Jersey–based amplifier modification shop founded by Rob DeAntonio, operating out of The Amp Shop in the Trenton/Hamilton Township area. The business specializes in modifying preamp modules for the modular Randall MTS, Egnater, and Synergy platforms, transforming customer-supplied donor modules into replicas of iconic tube amplifiers. Donor modules are not sold by the shop — players source their own Randall or Egnater modules and send them in for tailored modification work.

The catalog spans dozens of voicings inspired by classic and high-gain amps, including the JF6550 (a 5150/6505-style module), the 5F6JFM (Bassman-style), the MKC+ (Mark IIC+-style), the SL-OD100 (SLO-100-style), the Blackout (Dual Rectifier-style), and original designs such as the XMG and the RVerb. Mods can be ordered with optional switchable features like Midshift, Tight, Tone Stack, Midsweep, and diode clipping. The shop is well-known within the MTS module community, with a long-running presence on the MTS Forum and Rig-Talk, and has modified thousands of modules for guitarists chasing specific amp tones in a swappable preamp format.

Jaded Faith has 2 products cataloged on Equipboard, including Guitar Preamps.
