Description

The Marshall JTM45 2245 is an absolutely stunning recreation of one of the world's most legendary amplifiers. If you believe the very best guitar tones were from the '60s or '70s rock realm, you're in for a treat – it's likely that an amp just like this was used to create them. With beautiful cleans and warm, smooth overdrives, the 2245 JTM45 is about as authentic and old-school as it gets!

Smooth Overdrive

Back in the 1960s, amplifiers didn't really overdrive that much unless they were cranked to ear-splitting volumes. Every so often someone would manage to get a great tone with a slight bit of breakup, but nothing like what these vintage Marshalls could achieve.

A trick that many guitarists used with their vintage JTM amps was to run channel 1 into channel 2 using a jumper patch cable. By doing this, you could go from a crystal-clear clean to a beautifully smooth overdrive with some fuzzy top-end sizzle. In other words, that iconic Marshall crunch.

Classic Simplicity

This amp adheres to a classic formula; before the days of multi-channel amps with complex EQ sections and voicing switches. The Marshall JTM45 2245 is a simple amp with presence, bass, middle and treble controls, and independent 'loudness' controls for its channel 1 and 2 inputs.

And although the JTM45 lacks an effects loop, it still reacts beautifully to stompboxes plugged into its front end. Use you favourite overdrive or distortion pedals to really push the valves into saturation!

Amp Heads

An amp head contains the core tone and power of a guitar amplifier without the built-in speakers, allowing you to pair it with the cabinet of your choice. This setup offers greater flexibility over sound and volume, as different speaker cabinets can dramatically change the feel and character of the amp. Amp heads are available in valve, solid-state, and hybrid designs, ranging from low-wattage studio models to high-powered touring rigs. They’re ideal for players who want a modular setup, precise control over their tone, and the ability to adapt their rig to different venues, cabinets, or recording situations.

Amps

Guitar amps cover everything needed to amplify, shape, and project your guitar sound, from small practice setups to full stage and studio rigs. In this category you’ll find combo amps, separate amp heads and speaker cabinets, covering valve, solid-state, and hybrid designs, each offering a different feel and response. You’ll also see modelling and digital amps, built-in effects, footswitches, attenuation solutions, replacement speakers, valves, and essential accessories to keep an amp performing at its best. Whether you’re chasing pristine cleans, classic crunch, or modern high-gain tones, guitar amps and related gear are all about finding the right balance of power, tone, and control for the way you play.

30W

Products with the 30W tag have an amplifier or power stage whose stated output is 30 watts. Wattage alone does not determine perceived loudness, clean headroom or suitability for a room: speaker efficiency, impedance, cabinet design, amplifier type and how the power is measured also matter. Compare the complete specification and intended practice, recording or performance use.

Amp

An amp is an amplifier used to boost the signal from a guitar and shape its overall tone and volume. It plays a major role in how a guitar sounds, influencing everything from clean clarity to natural overdrive and distortion, and is a core part of any guitar setup for both practice and live performance.

Amp Head

Guitar amp heads contain the main tone-shaping and power section of an amplifier, designed to be paired with a separate speaker cabinet. They let you choose different cabinets to suit your sound and setup, offering flexibility for home, studio or live use. If you want control over volume, tone and character without being tied to a single combo format, amp heads give you a modular way to build the rig that works best for you.
