Owner Insights

We analyzed real musician discussions from forums and Reddit to find what players love, question, and tweak about Marshall JTM45 2245 30W Reissue Tube Guitar Amp Head.

Features and functionality

  • The JTM45 lacks a master volume, which means it requires an attenuator or alternative modifications for volume control without sacrificing tone.

    Source
  • Weber MASS attenuators are cited as effective and reasonably priced options for managing JTM45 volume without significant tone loss.

    Source
  • The Fryette Power Station 2 is highlighted as a top-tier attenuator, offering continuous volume control and enhanced functionality compared to simpler models.

    Source

Mods and upgrades

  • Post phase inverter master volume (PPIMV) can be added to maintain the "cranked" amp sound, with specific mention of the "LarMar" PPIMV as a recommended option.

    Source
  • Bluetone amps can custom-build JTM45-style amps with power scaling and post-phase inverter master volume, offering more flexibility than the stock reissue.

    Source
  • Swapping the Plexi's 4n7 bright cap for a 220p is suggested to tame excessive brightness, though it's a complex mod due to PCB design.

    Source

Comparisons

  • The Bogner Goldfinger 45 Superlead offers classic and hot-rodded Marshall tones without needing an attenuator, providing a modern alternative to the JTM45.

    Source
  • The JTM45's tone is often likened to a Fender Bassman, whereas the Plexi 1987x offers more gain and brightness.

    Source
  • The JTM45 is described as having a more "squishy" sound, while the Plexi is tighter and pairs well with overdrive pedals.

    Source

User experience

  • The Bluetone Loadbox is praised for preserving amp tone, but its limited attenuation settings (-20, -15, -12 dB) are more suited for home use than live performances.

    Source
  • A JTM45 owner mentions it works well with an attenuator on small stages, maintaining versatility across different gig sizes.

    Source

Build quality

  • The JTM45 and 1987x reissues use the same PCB, making mods challenging due to difficult access to solder joints.

Critic Reviews

Marshall JTM45 Tube Amplifier Amp Inside Out Review

tonymckenzie.com

The Marshall JTM45 Reissue promises the classic rock sound but isn't an exact replica of the original JTM45. While it delivers excellent sound quality and build with Marshall's reliability, purists may miss the vintage nuances. It's loud, making it ideal for gigs but challenging for home use. The lack of an effects loop and the high price tag are drawbacks. Still, with the right cab, it's a solid choice for blues and classic rock enthusiasts. For those eyeing modern tones or extreme genres, other options might be better suited.

"The first amp I ever bought was a Marshall, I've tried everything but I found MY sound in the JTM45. I think the JTM45 Bluesbreaker defines Beach Slangs sound, it's our not so secret weapon"
