slaving amp heads

[floyd1]

hey guys here is a ? for you. I have two amp heads and i want to use one for a slave. I run the second head from the line out of the first(other side of stage). My ? is ,is this safe it seems like i can barely turn the second head up past 1/2 on the volume. its almost like the first head is driving the second! Am i doing somthing wrong! I dont want to damage the second head. Thanx

Re: slaving amp heads

you are running the line out of one head into the line in of the 2nd or the input of the 2nd

The guitar imput on the front. there is no line input on the amp. B52 tube head line out into front guitar imput on kustom quad 200 ss head.

Re: slaving amp heads

Normally slaving involves sending the signal from the preamplifier of amp A into the POWERAMPLIFIER of amp B.

The way you have it, you are sending the signal from the preamplifier of A into the PREAMPLIFIER of B.

Preamplifiers are designed to take an UNamplified signal, not a PREamplified signal. Will it damage the Kustom? Maybe, depends on how tough it is.

I wouldn't do it this way.

Totally right!

Pre out (send) -> Pre In (return).

If you don't have a effects return or line in, split the signal before the amp. Something like a splitter or a stereo chorus or something of the like...

Re: slaving amp heads

this might sound cheazy and lame, but you could run the line out of the first amp into a volume pedal or something and then send that to the second...

There's 2 ways of doing it.

Slaving. Preamp out of amp A into the FX return of amp B. If it doesn't have an FX loop, you're sort of out of luck.

Daisy Chaining. It always works on 4 input amps like plexis and bassmans, but might work on 2 input amps. However, you're still utilizing both amp's pre's.
You plug your guitar into amp A's input, and run a cable from amp A's 2nd input over to amp B's 1st input.

I'm pretty sure (at least on my amps) if a plug in either of the inputs, the other one is shorted.

Is the Kustom a bass amp? Does it have an input pad for active instruments? (an active/passive switch or input)

Dude, you lost me, how can a second INPUT of an AMP A send anything OUT to
a first input of B ????

Now, as far as slaving, Laney TI100 - Iommi's amp has one of the best slave/loop designs out there.

Re: slaving amp heads

I might be wrong about 2 input amps. Goldenboy is probably right about the 2nd one being defeated when the first one is used. I think you can only daisy chain using 4 input amps. Basically, it's just splitting the signal using input jacks instead of a pedal.

Especially on older amps, the inputs of the amps are in paralell. Therefore a plug into input 1 of amp A, goes into the preamp of amp A. If a plug is put into input 2 of amp A- the signal is taken from the same path to where ever the plug goes (amp B or channel 2 of amp A... etc...)

If you look at older Marshalls, you'll often see a jumper going between inputs 2 and 3 on the amp with the guitar lead going in one. That's because older Marshalls have a channel I and II that are voiced differently. In effect, you're taking the guitar signal from channel one out of the input 2 and into input 3 (input 1 of channel II)

Dig?

I don't think it's a 4 hole issue, I think it's actually a MV issue- as it's not just the voicing of the "channels" it's the sensitivity of the input. I think.
