Condition Notes:
– Condition: 9.5/10
– Any wear of note: Both the head and cabinet are in amazing shape overall with no real notable wear. They may show very light signs of use upon very close inspection as they are used, but there’s nothing of note. Really in incredible shape.
– General notes: This is truly a really sweet rig! Giving you gorgeous vintage JTM tones at a reasonable wattage (20 watts with a switch to go down to 5 watts!) without the price tag of a vintage amp! You can jump the channels or use them separately just like on the old Marshalls too! Really allowing you to sculpt the amp to you and opening up more EQ options. And the head and cab look incredible together! Marshall really gave these a gorgeous aesthetic that’s vintage and timeless. A really awesome rig for anyone looking for vintage Marshall tones! And both made in the UK!
– Accessories included: Power cable only.

From Marshall for JTM Studio 1×12 Cabinet:
STUDIO JTM 1×12 CABINET
Compact 1×12″ cabinet for the Studio JTM range.
———-
The Studio JTM 1×12 Cabinet brings the iconic tone that sprung Marshall to the forefront of rock ’n’ roll in the 60s to today. This 1×12″ cab has been designed to be paired with the ST20H to create a small but perfectly formed vintage rig or used as an extension cab for the ST20C.
The smaller scale of the ST112 gives players the power of the authentic Marshall tone, in a more compact design. With Creamback Celestion speakers, this cab offers that definitive vintage tone.
