I have those racks efects:
CHAMELEON 2000 ( PREAMP + MULTIEFECTS)
JMP-1 (PREAMP)
DBX (COMPRESOR)
BBE (SONIC MAXIMIZER + NOISE REDUCTION)
BOSS GT8

I thought to conect them like this:

Guitar --> MAXIMIZER (BBE)--> JMP (with loop to GT8) --> NOISE GATE (BBE) --> DBX COMPR --> CHAMELEON

But I have lot of problems because there are a lot of noise, I think I would buy better cables, what do you recomend me??

Thanks wink.gif

Hi Juan,
The hum or noise sounds like it may be an earth/mains loop issue. (Low frequency hum at the same frequency of mains cycle - 50 Hz in the UK/Europe so about a low bass A?)

Good cables are a must - best you can afford usually. If you can, and if the gear has the i/o to do this, try using balanced trs or xlr cabling to hook it all together. You often get mains hum (which may be the problem here) accentuated because of unbalanced line. (A standard guitar jack is unbalanced, xlr speaker and trs are balanced.)

Getting rid of hum can be a bit of a trial. A quick fix, if any of the rack outboard has the facility, is to use a 'ground lift' switch. (There's also a way of re-wiring a 3 pin electric plug but I'm not going to say what it is as it's dangerous and I'd rather not encourage its use.)

It maybe just be one bit of the outboard that is causing the issue. Unplug them all and reconnect and try them out one at a time to see which is/are causing the hum. Also sometimes you can reduce hum by swopping the cables around (if you can't use balanced) or just putting the gear in a different place.

Another fix when you have lots of equipment that are all connected in series (like yours) is to connect to the mains in a star format via a single multiway plug board/trailing gang socket (not sure what these are called in Spain - it's the electrical connector where one end plugs into the wall and the other lets you plug lots of bits of kit in to it.) What that means is all the outboard should plug in to a single electrical point on the mains circuit. Because you have more than one piece you have to use a multiway - if you have so much outboard that a single multiway isn't enough then you plug extra multiways into the first one and the outboard then plug into them. Have to say that many electricians do not like this as you are placing potentially a lot of load on a single circuit - when I spoke to my electrician he howevcer was cool about it and said it was the best option! So I do it and it's what I've seen done continually in recording studios. (I put all my outboard effects on one plugboard/multiway; pc, computer screens on another; guitar amps on separate ones and so on.)

If none of the above works try to get a Direct Injection box between the bit of hardware causing the hum and another in the chain.

On your equipment chain: try the compressor before the distortions and the BBE either just before the Chameleon or the power amp.

Cheers,
Tony

Best tip from Tony again smile.gif.
Ground,good cables and balanced outputs are of great matter here.
Also try to use hush from Chameleon,it works fine. smile.gif

Oh yeah,compressor should be before distortion/preamp and Maximizer before poweramp.
Now,are you using drive from JMP or Chameleon?
Guess EFXs are from Chameleon so JMP is for drive,right?

Yeah, My intention is to use the JMP distortion for solos and use both distortions (JMP + CHAM) for rythms, because I like a lot the Chameleon Mega distortion.
I try to find ballanced cables, do somebody know where can I find them in internet ?? I visit thomann and Music Productive but I cannot find them. This eveing I have gone to a music shop but there weren't sad.gif
