Aug 09, 2013  Being more of a Marshall guy - I own a DSL 100 and a Vintage Modern 50 watt - when they put out the JMD:1, I was interested to see if they could do a better job of modeling their own amps than other devices. When they dropped the price from $999 down to $599, I figured 'What the hell', and pulled the trigger. This preamp has every classic Marshall tone or sound you remember from the golden days of rock, 70’s, 80’s, even 90’s. Using in conjunction with a JFX-1 effects unit with a RJM Mastermind midi Foot Conttoller for 100’s of settings presets and combinations.

Our business model is not set up to support this.QuestionWhat do you recommend running the levels at in order to keep noise to a minimum?. Power Amp - We recommend setting the volume controls wide open / full up. Preamp - We recommend using the 'Level' control on the front panel as the over all System Master Volume.

This should be set to approximately 9:00 to 10:00 for stage volume. The setting varies depending on the wattage of your power amp. You must also adjust the internal volumes on each patch/channel. Gain Patches - In order to keep noise to a minimum the 'Volume' should not exceed 12. Adjust OD1 and OD2 to taste. Setting OD1 & OD2 to 20 will give you maximum gain. Clean Patches - For maximum clean headroom and improved clean tones we recommend setting the 'Volume' to 20 and keeping the front 'Level' control set lower.

Clean 1 - Only engage 'Clean 1' and set to 12. Clean 2 - Engaging 'Clean 2' will give you a Mid Boost with added breakup. Note - For all other settings please refer toDo you program any new program patches? If so, where are they stored?. Yes we program (8) new patches for you free-of-charge.

The settings numbers are; 92 - 99FX Loop QuestionI’m interested in changing the FX-Loop on my Marshall JMP-1 from parallel to series. Is this possible, and if so are there any negatives to doing this? How much would the mod cost?. In our honest opinion; The effect loop on the Marshall JMP-1 is less than ideal. For the best results we recommend the following; Go out of your JMP-1 Main Output - Into your effects - Into your power amp. Note - for best results all instrument and speaker cables should be high quality.Stereo Output Question - I have a stereo power amp that I am using with the JMP-1 to drive (2) speaker cabinets. One output jack of the JMP-1 is going to the left side of the power amp and the other output goes to the right side. Both Level controls on the power amp are full up / on '10' but one speaker cabinet is louder than the other. Why is this and how do I resolve this?.

Explanation - The 'Level' control on the front panel of the JMP-1 controls how much output is sent to the Output Jacks. This control is what is known as a 'Dual Ganged' control pot. IE: When you adjust the 'Level' control you are simultaneously adjusting (2) control pots. The problem is that both pots on the 'Level' control are not matched. IE: as you increase the Level there will be spots where one side is louder than the other. All replacement pots have the same problem. Solution - 1.) Adjust the rig to the desired stage volume. 2.) Use the power amp's Level / Volume controls to balance the volume.Data Control Question - I would like to get the data knob (the component itself - not the plastic knob-cap) replaced – it turns rough and it skips numbers when turning so that it’s difficult to land on the patch you’re trying to select.

Marshall Jmd 50

I want to ditch the Marshall footswitch that came with my JMD combo. I play many different styles for $$$ and need more versatility in my rig such as more presets on one bank before having to switch banks (4 JMD:1 presets per bank is very limiting otherwise, I like the footswitch). Decided to pull out the ol' vintage ADA MP-1 midi foot controller (MC-1) and try it. Hadn't noticed my ADA MC-1 controller uses a 7-pin connector that will not even plug-in to the midi-in of the JMD:1. Obviously the JMD:1 has a 6-pin jack that I hadn't noticed either.First of all, what type of 'midi' cables/jack/adapters can be used with the JMD:1's 6-pin 'midi-in' connector?

Standard midi seems to be 5-pin, the JMD:1 is 6-pin and my ADA MC-1 uses what seems to be a proprietary 7-pin DIN connector which, isn't actually a midi cable if I'm to understand that correctly. (Although, believe little or none of what you may read on the web, and only half of what you actually see for yourself!:-P)So is there a remedy for using my ADA MC-1 controller, or am I going to have to purchase another brand of midi controller for my JMD:1?

Are there 5, 6, and/or 7-pin adapters out there somewhere? If they're there I'm not finding them. I've searched for a couple of hours now. I've found other types of custom adapters from a few sources but nothing that would indicate a remedy for my particular situation.I can purchase a new controller. But I never had any problems with the MC-1 all of the years I used it and am still pretty familiar with it.

Besides, it's just sitting around being all 'vintagey' and stuff thought I'd get some use out of it again.Thanks in advance for any and all help. I appreciate your time!By the way -. The JMD uses standard 5 pin MIDI.

I know the manual (incorrectly) shows a drawing of a 6 pin MIDI jack, but if you look at the back of the amp itself, it's a 5 pin jack.I've been using the Behringer FCB1010 and 5 pin MIDI cables with the JMD for almost two years now. And once you get used to 10 presets per bank, you won't want to go back to that Marshall pedal.I'm not familiar with the ADA pedal, so I don't know if it's truly MIDI or a proprietary system.

I did use an Egnater amp in the past that had a 7 pin MIDI jack; I used 5 pin MIDI cables with it and it worked fine. The extra pins on the Egnater were for phantom power, which I did not use. From looking at pics on ebay, the MC1 has a 9VDC or AC power jack.

If you use a compatible power supply with the MC1, and a standard 5 pin midi cable between the MC1 and the JMD, I am sure it will work perfectly.The reason for the 2 extra pins on the MC1 is for remote powering. If you use a 7 pin cable between the MC1 and a MP1, you won't need to plug in a power supply to the MC1 as the MP1 will provide the power.

But plug a supply into the MC1, and it will operate as a standard midi footswitch with any device that accepts midi program change commands, and will do this over a standard 5 pin midi cable.
