The Marshall JTM45 tube amplifier head is widely considered to be the definitive '60s Marshall. With 30 watts of power channeled from an all-tube signal path, you'll command the legendary guitar tones of '60s rock legends. The JTM45's sonic sweetness comes courtesy of a GZ34 tube rectifier, which imparts the natural sustain and compression the JTM45 is famed for. Simply put: you'll love how it sounds - and feels - to play through the Marshall JTM45 tube amplifier head. Marshall JTM45 Tube Amplifier Head at a Glance:

  • Your guitar will sing
  • Vintage reissue
  • Low wattage for a vintage Marshall

Your guitar will sing If vintage blues and rock tones are what you crave, then you'll love the Marshall JTM45. This isn't a high-gain amp for metal, nor is it a programmable, multi-channel monster. This is the guitar tone that shaped the sound of '60s blues and rock, from sweet and smooth clean tones to overdriven, growling dirt. One channel and basic tone controls are all that's needed for iconic tone. And if you need to push the JTM45 to the limit, just put your favorite gain boost pedal in front of it and listen to your guitar sing. Vintage reissue Part of Marshall's Vintage Series, the JTM45 amp head is an exact re-creation of the legendary amp from the '60s. Also known as the 2245, the JTM45 packs three ECC83 preamp tubes and a pair of 5881 power tubes for incredible tonal prowess. You also get the revered GZ34 tube rectifier, which is responsible for the JTM45's smooth, singing quality. Low wattage for a vintage Marshall The JTM45 only uses 30 watts of power to create its epic tones. That's pretty low power when you consider Marshall's other models at the time. But 30 watts is perfect for live use in small- to medium-sized venues, and it's ideal for recording. You can get the sound of a fully-pegged tube amp at a much more reasonable volume level, reducing mic bleed in your studio and your onstage volume when gigging out. Marshall JTM45 Tube Amplifier Head Features:

  • Accurate reissue of the legendary JTM45 amplifier, a '60s rock legend
  • 30 watts of power, perfect for gigging and recording
  • GZ34 tube rectifier adds natural, smooth compression and sustain to your tone
  • Sounds great with gain boost pedal in front of it
  • Straightforward control set is all you need to craft a range of vintage '60s guitar tones

Take control of the iconic tones of rock's revolutionary days with the Marshall JTM45 tube amplifier head!
