Legendary Tones George Lynch Mr Scary Mod Plug-In High Gain Tube Modification Module - Reverse Wire

Maximum quantity available reached.

Legendary Tones Mr. Scary Mod – Handmade in USA, 100% Pure Tube, High Gain Module for Marshall Amps (and more!)

This listing is for the REVERSE WIRE version (***more info below)

Created in collaboration with George Lynch, the Mr. Scary Mod is a custom-modified version of the Hot Mod V2. Want to supercharge your classic Marshall amp with more gain without applying a permanent modification? Then read more below and welcome to the Mr. Scary Mod!

George tried the original Hot Mod V2 (HMV2) in his Marshall and enjoyed it, so Legendary Tones decided to collaborate and do a custom-voiced version specifically for him. So instead of the HMV2’s two-position Hot Switch for two pre-set gain stages, they added a gain knob that goes from unity gain all the way to scorching hot on the Mr. Scary Mod. And just like the original HMV2, all the clarity and low-noise characteristics have been retained. They also added a Deep switch to help provide a bass boost when desired or when using a guitar that might otherwise be a little thin. With the Deep switch off, low end is tightened and it serves as a slight bass cut for clarity.

Originally released as the Lynch Mod in February 2021, the updated Mr. Scary Mod features the same circuit as the Lynch Mod but is now equipped with a tube mix combo of 12AT7/12AX7 per George’s preference as well as a facelift in a newly redesigned electro-galvanized steel enclosure.

The Mr. Scary Mod adds an adjustable 100% pure tube gain stage on top of the cathode follower V2 position, keeping note definition and articulation while further increasing sustain. Each Mr. Scary mod is meticulously built and wired by hand in the USA, one at a time, and tuned using high-grade components. Equipped with a single ECC81 (12AT7) in the first position and ECC83 (12AX7) in the second, the Mr. Scary Mod can clean up beautifully when rolling down your guitar’s volume, and still adds scorching gain when you roll it back up. This is a gain stage that’s been tuned and approved by the ears of the maestro George Lynch himself and is incredibly dynamic and touch-responsive.

Friedman Amps:
Runt 50 (V3), Runt 20** (V2) and JJ Jr.**(V2) are each compatible with the reverse-wire version of the Hot Mod V2 Evo and Lynch Mods (use in V3 position of Runt 50).

**NOTE 2: While the Runt 20 (reverse wire) and JJ Jr. (reverse wire) models are sonically compatible with the HMV2E and Lynch Mod/Mr. Scary Mod, the head enclosures are too shallow and don’t have enough depth to fit the HMV2E chassis without FIRST removing the amp chassis from the head box. So if you would like to use the HMV2E with these amps, you first need to remove the chassis bolts, slide out the chassis, install the mod, and then slide the chassis back into its head box and retighten the chassis bolts.

Popular amps that the HMV2/Lynch Mod/Mr. Scary Mod DO NOT WORK with include: Marshall Silver Jubilee series, Marshall Origin series, Marshall Vintage Modern Series, Mesa Boogie Mark series amps, Bugera 1960, and Hiwatt DR series.

Some History

Back in the late 1980s, Mike Soldano of Soldano Custom Amplification released his original Hot Mod, a design based around use of rare 6C10 (and then later 6K11) tubes. These tube types added more gain much the same way that the HOT MOD V2 EVO and Lynch Mod do, but they had limitations. The tubes were long out of production, getting expensive to find, and often would become microphonic and therefore limited in capability. The original Soldano Hot Mod had lots of gain and delivered on its promise, but it was ultimately taken out of production primarily due to the challenges with finding consistent and quiet tubes.

Still, the original Hot Mod was the inspiration for the HOT MOD V2 EVO and Lynch Mod, which function in much the same way as the original, but now have additional circuitry that further stabilize the design, provide more clarity, and deliver a wider, more controllable range of gain on the preamp control of the amp rather than coming onto high-gain territory too quickly. And of course the HMV2E and Lynch Mod now also uses a 12AX and 12AT7 tubes that are commonly available.
