The Marshall JTM 100 PA is one of the rarest and most powerful Marshall amplifiers of the late 1960s. Originally developed as a PA amplifier for vocals and instruments, it quickly became apparent that this 100-watt monster amp was one of the most sonically pure and versatile Marshall amplifiers of its time.
With four KT66 power tubes, this amplifier offers an extremely open, warm and clear sound, which is particularly distinguished by its excellent headroom reserves and natural tube saturation. Compared to later Super Lead and Plexi models, the JTM 100 PA has a slightly softer, more musical distortion that is perfect for blues, classic rock and early hard rock sounds.
The hand-wired turretboard construction ensures extreme durability and unparalleled sound purity. Like all JTM models, the JTM 100 PA has an extremely dynamic tone that allows guitarists to control the sound solely through their attack and guitar volume.
A special feature of this amplifier is its four-channel configuration, which allows connecting various instruments or microphones simultaneously. In practice, many guitarists have „jammed“ the channels to create an even tinier, more dimensional sound – similar to the legendary Marshall Super Lead Plexi from 1959.
The classic 3-band sound control (bass, middle, treble) with Presence Control ensures precise fine-tuning of the tone.
The Marshall JTM 100 PA is a powerhouse with unparalleled dynamics, warmth, and punch. Its extreme rarity, unmodded circuitry, and fantastic sound quality make it a perfect choice for blues and rock guitarists looking for the authentic sound of the late 60s.
