Honey!
I've got an handmade replique of this fantastic amp and totally love it! The sweet warm cleans and the rough, rocking overdrive are what everyone who is into blues and classic guitar sounds wants!

It is also the loudest 30 to 45 watts you will ever hear through a vintage-accurate marshall cab with alnico celestion speakers or clones... but tonally, one of Marshalls handful of shining moments. They got it right first try. I always much preferred the JTM45 to the superleads I used to favor...

Used all over many clutch albums by Tim. Tim has stated that during the recording of 2013’s “Earth Rocker” album, he says the only amps he used on that record were a Marshall JCM900 head and a Marshall JTM45 head. It was also credited as one of the amps used on Clutch’s 1995 Self Titled record however it was credited as a JTM40 40 Watt head. Most likely though it is a JTM45 cause I couldn’t find any information on a 40 Watt JTM head.
