The Randall MTS Plexi module is an all-tube preamp designed for the MTS modular amp system, replicating classic British mid-gain rock tones from the late 60s/70s. It features rich harmonic overdrive, high touch sensitivity, and a bright switch, offering tones similar to the SL+ but with lower gain and a warmer top-end EQ
Key Features & Sound Characteristics
Tube Preamp: Two user-replaceable 12AX7 tubes.
Sound: Classic Marshall-style crunch with warm, mid-gain tones that are highly responsive to guitar volume changes.
EQ & Gain: Features a 3-band EQ (Bass, Middle, Treble) and a dedicated gain knob, allowing for classic rock to blues-rock tones.
Bright Switch: Adds high-end presence to enhance sparkle and definition.
Interaction: Similar in voicing to the SL+ module but with less gain and a slightly different top-end eq.[1, 2, 3, 4, 5]
MTS Module System Benefits
Easy Swapping: Modules can be inserted or removed from the RM-series amps via two screws.
Compatibility: Designed for use with Randall MTS amps (RM100, RM50, RM4)
NOTE:
I'm also selling an Egnater M4 Preamp, an Egnater EG 3/4 Dual Module and an Egnater COD Dual Module. Look for them, while they last, on Reverb.
