Members pol Posted September 19, 2006 Members Share Posted September 19, 2006 I just sold mine, it's an ok preamp, but nothing like a good head, i like the clarity it had, but prefer the distortion on my Poundcake. now i'm toying around with a sansamp psa1, it's really fun for some of those buzzsaw distortion and great cleans.

What power amp did you have? A Diezel or Bogner doesn't make me wanna sell my rig. Link to comment Share on other sites More sharing options...
Members pol Posted September 19, 2006 Members Share Posted September 19, 2006 i tried our bassplayers strategy 400, but the jmp1 sounded best thru the fx return on my steavens.much fatter and warmer then thru the strategy400I guess the 500 must sound different with those depth boost switches ?

Members petelaramee Posted September 20, 2006 Members Share Posted September 20, 2006 I've had one for about 5 years and it's great. Since having it modified by Voodoo it sounds even better - especially the clean. That being said - it's currently for sale. Link to comment Share on other sites More sharing options...

Members marshallnoise Posted September 20, 2006 Members Share Posted September 20, 2006 I had a JMP-1 and I loved it. It really was a great setup. But I will say that a damn good head is about the best tone you can get. It is just more organic. When I had my JMP-1, I was running it through a black faced Intellifex and into a Mesa 50/50. The Mesa was just awesome. Something about 6L6s that just sounded bad ass. Link to comment Share on other sites More sharing options...

Heys! I used the jmp1 together with the marshall 20/20 for over a year and i just sold the poweramp. Somehow i found that the tone was a little too mid rangey and lacked "fullness" and oomps. I just got a vht 2/50/2 3 days ago and i can assure you that it is a MUCH better pairing than the 20/20. It sounds very full and round now!

Members maninblk0073 Posted September 20, 2006 Members Share Posted September 20, 2006 hmm...the tone on "spiders" reminds me of Kurt cobain's tone with slightly more color. Link to comment Share on other sites More sharing options...
Members mrhiwatt Posted September 20, 2006 Members Share Posted September 20, 2006 I run my Voodoo modded JMP-1 in the effects loop of a GT-8. GT-8 into a Marshall El34 50/50 using 6l6 tubes. Run stereo into 1960A 4x12 with gt-75's. I've been using this rig for 6 months and have not felt compelled to search for a different amp or tone. My usual settingsare od-1vol 17gain 16bass 3mid -2treb 4pres 3bass shift offJMP-1 front output 1 oclock Power ampb voicing3/4 volumepres 1/4Control volume with gt-8 Gt-8 also is my midi switcher.I use about 300 mil sec analog delaya hint of chorus.

Yep I hade a strategy 400 and I like my 2:90 much better with the JMP-1, due to the deep mode the sound was just thicker at the end of the day... xgx Link to comment Share on other sites More sharing options...

Members 6130907 Posted September 25, 2006 Members Share Posted September 25, 2006 i just became a proud member of the marshall jmp-1 militia last night im running it with a mesa 50/50 into a peavey 4x12ms cab anyone have any tips on this unit? i think i read somewhere to run the output volume at -20db so you can crank the poweramp more...anything more like that?

Members pol Posted September 25, 2006 Members Share Posted September 25, 2006 that's useless, you won't be cranking the poweramp more at -20 db. It will allow you to put the put the master higher, but since your input signal to the poweramp is at -20 db, the poweramp wouldn't be working harder.

Actually it does make the power amp work harder when you run it lower. I've been doing that for 4 years or so. Run the preamp low and the power amp high.

You may want to swap out the EL34's in the 2/50/2 over to KT77's. They will take some of the mid hump out of the sound.You'll get more DT sounds from OD2 in the JMP1 with the mids around -1, gain about 17, no bass boost.Also, what speakers are you using?If you have V30's, that may be the problem.Steve Link to comment Share on other sites More sharing options...
Members gargamelesp Posted September 25, 2006 Members Share Posted September 25, 2006 im using a stock marshall cab with celestion g12t-75 speakers i just got the 2/50/2 and i think it would be a little wasteful to swap the tubes out so quickly! ah... actually im using an expandora as a boost pedal and i found that i prefered od1 as it seems to sound heavier. the lack of gain on that channel compared to od2 dosent really matter since im boosting it with a pedal Link to comment Share on other sites More sharing options...
Members 6130907 Posted September 25, 2006 Members Share Posted September 25, 2006 wow, i finally got to play my new setup today, and it sounds heavenly...i cant wait to try it out in practise and at our show on friday i need a footswitch though...what do you guys reccommend??keep in mind, i only need to change between a few patches on the preamp...i use a couple stomp boxes for my effects i just saw a tech21 midi mouse, and a g minor midi footswitch...i think i need something like that, if not that Link to comment Share on other sites More sharing options...
