MARSHALL PLEXI INPUT JACK WIRING

Jumpering Marshall Amp Channels | Sweetwater
A: Some Marshall amps, such as the JTM45, 1959HW, and 1987X are two-channel amps. However, these are not traditional channel-switching amps. Each channel has its own input jack(s), and to access that channel you need to plug into the appropriate jack. On these Marshalls, though, the channels are also voiced quite differently.
Input Jack Wiring - Jumper between channels no sound
Aug 04, 2019I have a Marshall 1987 MKII. I received it used last year. Since day 1 I have had an issue where trying to run the jumper between the two channels and plug into a 3rd input with my guitar results in 0 sound output. Each jack had worked independently, but jumpering did nothing. I am using the CLIFF style jacks with the 4 posts for each input andDoes The 1 Wire Mod Convert A Plexi Or Metal Panel To AApr 08, 2018Plexi / JTM Internal Jumpering? | MarshallForumAug 02, 2013JCM800 2204 50W-('81-'90) prefered year(sOct 27, 20104X12 1960A: What Wiring Do I have? | MarshallForumFeb 02, 2009See more results
