A Top-class Re-creation of the Stack that Started it All

Inspired by one of the most iconic stacks of the ’60s, the TC Electronic JIMS 45 Preamp Pedal packs an arena-ready overdrive punch into a simple stompbox form factor. This pedal’s tube amp inspiration comes straight out of 1965-era London, precisely modeled after the amplifier players such as Jimi Hendrix, Pete Townshend, Peter Green, and countless others used to revolutionize the sound of rock and blues guitar. Its intuitive control scheme — directly modeled after the original — gives you two channels with independent EQ controls to play with, while the secondary footswitch cranks up the heat with a switchable pre/post boost for 5dB of extra heat. Finally, flip the pedal over to the rear panel to be greeted by a smattering of additional controls and features, including an additional tone-sculpting Presence Pot and an official Celestion cab-sim-equipped DI out for effortless tracking

The amp that ushered in rock’s revolution

From overdriven power-chord fury to searing solo tones, the JIMS 45 delivers sought-after sounds in the realm of rock guitar. It’s lovingly modeled after one of the first models released by a legendary British amplifier manufacturer — if the name doesn’t give it away, the golden knobs undoubtedly will — famous for fueling rock guitar’s transformation into a harder-edged sound in the late ’60s. An uncompromising tonal tribute to the original model in all its 1965 glory, the TC Electronic JIMS 45 captures every detail and nuance of its inspiration’s tweedy response and smooth, mellow overdriven sound.

Footswitchable boost with dedicated rear-panel controls

Looking to crank up the grit? Simply stomp on the JIMS 45’s Boost footswitch to add 5dB of extra heat to your tone! Moreover, the “Pre/Post” switch gives you the power to choose where the boost is placed in your signal chain. While it can be placed at the end of the JIMS 45’s circuit for more volume and authority, Sweetwater guitarists find that cranking the boost up in the “Pre” section results in lush, saturated overdrive tones on even the mildest of pickup configurations.

A comprehensive set of functional features

Apart from serving as a spot-on amplifier emulation, the JIMS 45 is loaded with a vast array of quality-of-life functions to aid you in your practice, recording, and gigging endeavors. First up, the 2-channel design — with independent Normal and High gain controls — features fully independent tone-shaping options, with a dedicated footswitch to instantly swap between screaming lead tones and more restrained rhythms. In addition, the JIMS 45 boasts a dedicated DI for easy recording and performance, equipped with an official Celestion 4 x 12-inch G12M Creamback cab-sim IR emulation for the full dynamic response of a classic amp stack.

TC Electronic JIMS 45 Preamp Pedal Features:

  • Puts the raw, roaring tone of one of history’s most iconic British tube amplifier heads at your feet
  • 2-channel design with independent channel controls allows you to instantly swap between 2 of your favorite configurations
  • Independent gain controls for the Normal and High inputs
  • Footswitchable 5dB boost circuit supplies an extra helping of tonal authority, with pre/post and dedicated gain knob
  • Rear-panel Presence pot to further dial in your tone
  • Dedicated DI and headphones outputs for easy recording, performance, and practice
  • Built-in official Celestion 4 x 12-inch G12M Creamback cab-sim IR to give your sound a true-to-life space and response

Best Sounding JT45 out there!

I have played some good Marshall tone pedals, but this is the one that I have been looking for and could not find. What an amazing representation of a JTM 45. It feels very real straight out of the box all knobs at 12 o'clock. The price too. Though I paid for and really like the Universal Audio Ruby, I paid $ for it. It is worth it, but it made me pause to think of how many more pedals like that want to afford. Now we have TC finally getting amp emulation right. Home Run!

PS. Martin at Sweetwater is a great rep.

Good Budget Alternative

Good budget alternative to the Iridium. I only got the Iridium for the Marshall tones and that was good and with the Favorite switch I could dial in another Marshall tone. However, the Jims 45 offers more tonal options. First you can toggle between a green and red channel then each of those has a toggle to turn the boost on/off, so 4 channels total. Also on the back of the pedal there is a Pre or Post switch for boost channel. My preferred usage is to hook this up to my IKM Micro Monitors and it sounds really good. The headphones out with the emulated Celestion 4x12 Creamback IR sounds really good too. I love that that there is also a presence knob on the back for more tonal flexibility. Finally the DI out with Cab Sim sounds just as good as the headphone out for recording. This is a really good pedal if you can get past the name and look of the logo. I think JM45, M45 or Plexi 45 might have been better name options. Also, I would have liked if they used the Marshall font. Kind of how they used the Fender font for the Combo Deluxe 65 pedal. I'm really big on the aesthetics of a pedal. I think it is just important as how it functions. So I deducted one star for that. Before I got this pedal I really thought I was going to return this pedal b/c of the look it but it's so featured pack and sounds good that I am going to keep it.

TC Electronic Jims 45

Great JTM 45 sounds. Great to save on CPU tracking digitally in a studio w/o using a plugin. Check out my demo

Great Pedal.

This is a fun way to get that early Marshall tone in your rig. It's tons of fun to play around with and it's good enough to gig with as well. I'd probably try to use the real thing for recording but crowds won't be able to tell the difference. I can use this as the last pedal in my signal chain and go directly to the board and don't have to take an amp to a gig if I don't want.

Home run

I own @ 10 Marshall in a Box pedals (and as many plugins) and this one has ended the journey. To be clear, it's not specifically designed to go in front of a traditional amp like a Box of Rock etc. - it's a full
preamp that doesn't need an amp's front end tone stack.

Having said that, most amp-in-a-box pedals still sound like pedals. The TC Ampworx line is designed to be a desert island small box that can be used for DI applications where a full amp isn't practical, so it's in the same space as Strymon Iridium or Walrus ACS1.

Having owned both of those, the TC was the winner for me for Marshall sounds. Pros:

Best combination of warm bassy lows and glassy top I've heard in a digital JTM45 sim

High/low input volumes and eq knobs act like a real JTM45 - which is to say they don't do much. The value of the tone stack on an old Marshall is to fine tune the overdrive character, not radically alter the response. Most other digital JTM45 sims (especially plugins) create a phasey mess with the eq knobs. This is especially annoying when using external fuzz pedals - the TC takes all my fuzzes like an amp.

I prefer the IR setup to the Strymon or Walrus - simpler and gets you playing quicker. There's no computer hookup needed - one output has the IR, the other doesn't. Use whichever you need.

The included IR is a Celestion Digital Creamback in a 4x12. Usually I'm not a fan of Celestion's own IR's, I find them a bit hollow and tubby sounding. This one sounds great for whatever reason - I've compared it to my usual trusted IR plugins and it holds up well.

Only con is I wish they'd included a 2nd IR for an open 2x12 Beano tone. But this is meant to be a simple plug and play tool, and you can use any IR loader for that.
