1968 Marshall JMP Super PA 100

This rare, holy-grail Plexi-era head shares the exact same legendary Dagnall transformers and EL34 power section as the iconic Super Lead and Super Bass amps from Marshall's absolute pinnacle build year. Because its preamp circuit lacks aggressive high-pass filtering, it naturally delivers the thicker, warmer, and highly coveted vintage Super Bass voicing. At lower gain stages, the head delivers deep, punchy headroom, but when pushed, it blooms into a monolithic, sag-free crunch with deep low-end growl and smooth top-end sweetness. This capture sits in what I would call the sweet spot. With hum buckers you will notice a some crunch but with singles it is just on the edge. This is how I run the amp live, a boost pedal or overdrive will send it soaring into british crunch heaven and a light touch or rolling back the volume will maintain the delicate almost fender, but thicker, like cleans. This Capture is a Direct Amp only capture and will pair beautifully with Our TJ3 Gen 3 IRs which are also available on the cloud. Signal Chain 1968 Marshall JMP Super PA 100 Direct Amp Head Capture
