1 watt, full-on Marshall.

Introduced in 2014 to celebrate Andertons Music Company's 50th Anniversary (1964–2014), the Marshall CS JTM145 was commissioned directly from the Marshall Custom Shop as an exclusive run of just 200 amplifiers worldwide. Marshall looked back to the very earliest 1964 JTM amplifiers, reproducing not only their unmistakable cosmetics—including the iconic white front panel and early block logo—but also their feel and musicality, scaled down to a genuinely usable one-watt format.

Offered here is serial number 100 of only 200 produced.

Condition is very good, showing only light, superficial signs of use. It comes complete with its original Marshall dust cover and original shipping box.

Despite producing just a single watt, the CS JTM145 is anything but a toy. The amp captures the spirit of the earliest Marshalls beautifully: rich cleans, effortless touch sensitivity, and that wonderfully smooth transition into overdrive as the volume comes up.

One of my favourite aspects is the interaction between the High Treble and Normal channels. Marshall internally linked the two channels, allowing you to blend brightness, body, and gain with remarkable precision, opening up a surprisingly broad range of tones from such a simple amplifier.

Collectors have taken notice over the years. With only 200 examples built exclusively for Andertons, the CS JTM145 surfaces only occasionally, and complete examples are becoming increasingly difficult to find.

A beautifully executed Custom Shop amplifier that combines collectible rarity with genuinely inspiring vintage Marshall tone.
