Recomended Mod's for a JTM45

[Gazza]

What types of Mod's can be done to a Marshall Jtm45/Bluesbreaker to make it sound more like the original.

Funny you should ask...

Just did the mods on my BB RI and they worked great (well, I haven't changed out the OT... yet).

Here's where I found all the parts:

www.clarkparts.net
www.angela.com
www.mouser.com

I used carbon film resistors in the signal path and carbon comp resistors in the power stages.

jtm45 RI mod's

I just did the entire set of mod's including OT and it's really fantastic. The amp sounds great with all my guitars, in particular my '67 335 and my PRS McCarty.

Simple mod...

Take your JTM 45 RI and replace the whole thing with a REAL JTM 45. It worked wonders for me!!!
