Setting Up A Rack

Yakult

Ok, If I can get a Marshall JMP-1, that means I will have the preamp gotten.

Would I be able to use my marshall as a power amp? Of would I have to buy a speciefic power amp?

Also what else would be needed?

If your marshall (i presume it's a combo) has an effects loop, you can use it. If it's a serial loop, all the better.

Part of the logic behind a rack setup is to get everything in one box, so a rack-based processor would be handy, but not necessary. You'll also want a switcher for the JMP-1, they can sometimes come with a simple footswitch, but if not, you might want a midi switcher of some sort. Small simple ones, and big floorboards are both available.

If you get a rack processor, you can use your midi switcher to switch the JMP and the processor at the same time.

You'll also want a rack case of some sort, if you plan on taking the JMP out and about. Otherwise it'll get scratched up the f*ck. Before you buy one, have a decide about what you plan on getting in the future so you can pick the best size for you.

Well I plan on using the marshall for now. Its a Dsl 401 so.. Im working over the summer and will have about 1500 to spend on a power amp and effects.

Well Im thinking about getting a Marshall El34 50/50, and the Gmajor effects processer!

How would I link it up if I had all of those above minus the marshall Dsl? Would I need just a cab?

That would work fine, the marshall power amp would be a great match for the JMP. I have a G-Major, they are fiddly but sound great.

You'd need a stereo cab (ie 2X12 or 4X12), or two mono ones. I don't think the marshall poweramps can be run in mono, both sides need a load.

To link it up, you'd just need a bunch of short cables. JMP -> GMajor -> Poweramp -> Speaker(s)

I have heard good stuff about the G major so! lol.. Its not too expensive either!
Does it have wah?

So I wouldnt have to buy two cabs then :P

Ok, I sorta knew how to link it up, just wasnt too sure.. But how would I get all that in Sync with a midi pedal? Thats what confuses me! lol..

So long as the cab you have/buy is actually a stereo cab (ie it lets you split it into two separate sides).

Some poweramps can be run in mono - i.e. you just leave one 'side' completely switched off. This is handy for smaller gigs where you might only want to bring a single 1x12 with you. However, im not sure if the marshall's let you do this, I don't think they do.

Controlling everything with a Midi pedal is just about learning how to use midi equipment.

Sorry to threadjack here but have a rack related question.

Is it possible (or advisable) to run a rack-mounted pre-amp into the input of a combo-amp that doesn't have an effects loop? Like just plug it into the input of my Marshall G30RCD?

I've never had any need for big cabs or high powered amps as I just make music in my house and can't crank up too high.

At the moment my setup is to have my Toneport UX2 hooked up to a Spirit Folio Lite mixer which goes out to my stereo with speakers placed at each corner of the room and two monitors on my desk. Doesn't sound amazing but perfect for what I want it for.

When I want to use my amp I plug into my Marshall and have it mic-ed up to the Spirit so I can hear the amp and the 4 speakers and monitors.

I suppose if it is advisable to go from a preamp into a solid-state combo amp then best bet would be to turn the volume on the preamp all the way down and just turn it up slightly as I go until I get a good sound

I dont think u can just plug it into the input =/

G major and a midi floorboard cant go wrong man, once u get it set up it would be very handy indeedy, if i as to go rack it would be a definite piece of gear for me


Kinda diff simple Q, is it a simple job to mod the parallel fx loop into a serial one, the one on my tsl is never 100% wet

Yeah the marshall allows that!

Cool! Any websites I should look at?

I'm pretty certain that you can run one single cab on one stereo side of the marshall poweramps.

I wouldn't go near the G-Majors myself, everything i've heard about them makes them sound like badly manufactured junk with control parts that fall off or break

Get a Rocktron Intellifex or Replifex. Sound great, supposedly more transparent than the G-Majors and built like tanks.

If you're using the TSL combo, You should look into changing the speaker in it. The one in there has a tiny magnet on it, doesn't handle bass all too well!

Its possible but the rack pre-amp will be coloured by the G30RCD's preamp.

Have a read of that. Then it'll just be a case of reading the specifics in the manuals of the MIDI units you buy.

If that's the case, than that's a good way to start building a rack setup. 50 watts into a 1x12 is more than enough for most folks starting out, and then you can add another cab when budget allows, or when you need the full stereo setup.

If you're doing that, just remember to switch the side you're using every now and then, to keep the valve-wear as even as possible.

G-Majors arent the best built units alright, but they do have sound quality compareable to units costing twice as much. It's probably the most popular 19" processor around today, and with fairly good reason.
