The NEW MGL50 “1981-2204” is a replica of my original 1981 Marshall JMP 50w master volume head that I’ve owned for over 30 years. Many customers over the years and myself think this is the best sounding original example they’ve heard. This new replica is so dead on that even I have a hard time picking which amp I’m playing when both are on an amp switcher going thru the same speaker cab. We’ve matched all the components in values and tones along with accurate voltages throughout the amp circuit. So, a faithful 2204, and then add the updated features of the other MGL50 amps, including: Foot switchable cleaner channel with a separate master volume, Metropoulos “Zero Loss” effects loop w/ true bypass switch, negative feedback “Voicing” switch and NOS tubes along with hand wire turret board construction. There is also a mini switch on the front panel between the Master & Pre-Amp that will add more gain to the stock circuit. To keep the classic 2204 vibe going, Swanson Cabinets is making late ‘70’s JMP replica 29” head cabs covered in real Marshall black Elephant tolex for this amp (smaller Plexi style head cabs are also available in 24” and 26” sizes, custom tolex colors also available at no up-charge)
Some quick build notes: MGL custom Heyboer 784-139 output transformer. The power section uses an MGL custom wound Dagnall power transformer and choke.
PRICE $2,695.00
BUILD SPECS:
Mini Switches, Front Panel
The mini switch on the front panel between the Master & Pre-Amp knobs that’s labeled MOD & VIN, allows you to switch between 2 different levels of gain. In the down - VIN(vintage) position, it’s stock 2204. With the switch in the up MOD(modern) position, you get a noticeable increase in gain.
The mini switch to the left of the “FS” footswitch jack labeled HI & LO can be used to switch between the HI & LO Master Volumes when no footswitch is plugged in.
Mini Switches, Back Panel
The mini switch on the back panel labeled “Voicing” determines the amount of negative feedback in the circuit. When in the up “Modern” position you get the stock JMP-JCM800 setting. In the “Classic” position (switch down), you get more negative feedback which will be a little darker, sweeter and more compressed(more plexi like in tone & feel).
The mini switch to the left of the FX loop is a true bypass, so in the off position, the loop has no effect on the amp circuit.
