Power reduction from 20W to 5W at the flick of a switch
This amplifier provides you with the versatility to tailor your power output to suit your environment. Effortlessly select between 20W and 5W power output to seamlessly transition from the rehearsal room to the communal space and back again, without compromising on tone.
Inspired by the original JTM45
Reproducing the legendary, warm and smooth tones of the original JTM45, the Studio JTM range looks as good as it sounds. Let the all-valve, era-defining sound of the JTM steal the show, whether playing at home or on stage.
All-valve
This instantly recognisable tone is driven by two ECC83 preamp valves, two 5881 power amp valves and one ECC83 phase splitter.
Built in our UK factory
Meticulously crafted in our Bletchley, England, factory the Studio JTM features classic Marshall touches such as a robust metal 'coffin' logo with golden piping and beading that pays homage to the 1960s. After extensive years of development, the Studio JTM delivers the timeless and velvety tones reminiscent of the original JTM. Β

Common questions
When will my order be dispatched?
Verified orders are shipped within 24 business hours of payment. Some items move from our remote facility to the delivery warehouse first, which takes a little longer. Every instrument is tested before it leaves us. If anything is delayed beyond that, we will call you and ask whether you still want to go ahead.
How long does delivery take?
Most customers receive their order within 5–6 business days. Shipping is free on every order with no minimum. Instruments and pro audio are fragile, so each one is packed carefully rather than quickly.
What if I change my mind?
Start a return within 15 days of your delivery date, with the product still in brand-new condition. You can ship it back yourself, or we can collect it for 7% of the product value (minimum ₹500, maximum ₹2,000), deducted from your refund. Refunds are processed within 3–5 business days of the product reaching our New Delhi facility.
If the product arrived damaged, wrong, or with accessories missing, report it within 5 days and we cover the return.
Is the warranty genuine?
Yes. Ace Music is the official India distributor for Marshall, Natal, Tanglewood, Newen, Ashdown, Hebikuo, Furch and Oliver. Every instrument is genuine stock, carries the manufacturer's warranty, and is serviced by our own team in India — not shipped abroad.
