hey guys
heres the deal:
i have an ibanez chorus pedal (80s model i think) which sounds absoloutely beautiful till i use both the outputs, where it produces the hideous buzz, along with the guitar signal too. thru 1 amp it is fine, but 2 it isnt. but heres the stranger thing. i have 3 amps - a park marshall 30watt, a marshall acoustic 50watt, and a stagg bass 20watt. my main amp is the park, so that is always connected. now, when the other output is put to the acoustic amp, the buzz is not there whatsoever, but thru the stagg, there is the buzz. the amp is in working order as with a bass it sounds fine. well with a guitar it sounds fine except with that pedal.
sorry to drone on so much, im just confused!
thanks

you are using MONO (tip/sleeve) cables for in and output, and not stereo cable (tip/ring/sleeve)???

I accidently used a stereo cable once an my setup went crazy soundwise (and not in a good way :D )

best of luck
 
yeah i forgot to put that there were 2 outputs (you might have guessed that anyway) and im just using normal guitar leads which are mono right?
 
Hmmmmmmmmm Olfunk,

Funny that noise, now what will happen if you do connect both outputs to just ONE amp? Still a strange noise or? Of course you chorus will be gone, as both signals cancell each other out, so no more chorussing, but what about the noise is that there or............?

Perhaps there is something wrong with the Stagg?, since the chorus only makes the buss when it is connected to the Stagg and the other amp.

Eddie :)
 
It sounds like a ground problem. Does the stagg have a 3rd prong?

Try lifting the ground on the stagg.

tell me if im being a total dumbass, but what does that mean?

and by the way thanks for the help :)
 
If it has a 3rd prong on the AC plug, get one of those 3 prong to 2 prong adapters. The 3rd prong (the thick one on the bottom) is the ground.

My money is on a ground loop. That happens when the shields of two amplifiers are connected (as they are when a stomp box is connected to two amps) and the chassis grounds (the round pin on a three prong AC plug) "see" a difference in resistance to earth ground. A remedy is to lift the ground on one of the amplifiers by inserting a ground lift adapter where it plugs in to AC power.

NEVER clip the round pin off the AC plug of an amp (or anything else, for that matter) to ground lift an amp; use a ground lift adapter. DO NOT use a ground lifted amp in standalone mode (with its shield not linked to another amp which is grounded). To do either will expose you to risk of electrical shock.
