Marshall / JTM45 MKII / 1965 / Black / Amp For Sale
Marshall
JTM 45
1965 - Plexi Front/White back panel
Serial Number: 1457
This iconic head from the 60's is everything you'd expect from a classic vintage amp and more. The amp is honest original example with service parts changed(originals all included), period correct NOS valves and original iron. This example has one output jack. We think the tolex has been subject to some black paint at some point in its life but this all adds character. We have had this serviced so it is ready to be used and not just looked at, to create a reliable, usable tone machine!
This head has just been serviced by Dave Wittering at Prestige Amp Servicing, who is an ex-Marshall senior service engineer and is in full working order.
