This JVM 410H has been heavily modded with just about all the mods you could ever need.
It’s in great condition as the pictures attest to.
Foot switch included!
Please look at the pictures as they form part of the description.

Onto the mods:
-----------------------------
AFD100 Mod (pot)
For the Crunch Orange and Red and Clean Orange and Red, it will give you the ability to go from a very "raw" and aggressive distortion character (with the knob turned up) to a smoother, more "classic" distortion with the knob turned down. Mod is on a pot on the rear of the amp and can be completely dialled out of the circuit when turned all the way down.
-----------------------------
Gain VOLUME Mod (pot)
Allows adjustment of gain/volume on OD1/2 Red and Orange modes. This can be used to balance the OD1/2 Red and Orange modes with OD1/2 Green mode. Mod is on a pot on rear of the amp and can be completely dialled out of the circuit when turned all the way down.
-----------------------------
Negative Feedback Mod (pot)
Changes the way the power supply delivers power and provides more traditional power tube breakup at lower volumes. Mod is on a pot on rear of the amp
Compression Reduction Mod
This mod reduces compression and allows the amp to sound more open.
-----------------------------
1959 Plexi Cap Mod
This mod reduces squeals and glassiness at high gain and rounds out the high end.
-----------------------------
Choke Mod
Reduces noise in all channels by replacing the stock resistor with a choke. The amp feels much more organic, and the bass response is improved.
-----------------------------
C83 Mod
Reduce some of the “fizzle” from the gain channels.

Probably the best sounding Marshall you will hear - guaranteed!
