Using a Slave Amp

[sao]

Hi everyone, First post and I'm pretty sure I know the answer but its always good to check these things.

I have a Sound City 120 watt PA head, it sounds amazing the only problem is that the preamp had a silly amount of hum (probably needs re-capped but I cant afford it just now).

So my solution to this is to make the sound city head a slave of my Marshall 3520 as it has a far quieter and easily EQ'd preamp by sending the signal from the Marshalls Effect loop out to the Sound Citys effect loon in?

This will bypass the noisy Sound City preamp and will cause no ill effect to either amp, Correct?

(Both heads are connected to cabs as well)

Correct. Actually with the Marshall being solid state it shouldn't need a load to work just fine. (disclaimer, SHOULDN'T).

Seems like a lot of amp to cart around though, are you using both heads anyway? I suppose you are because you say they're both connected to cabs. Does the sound city have an insert? Try a noise gate in there.

Thanks

The sound city does have an effects loop and I tried a boss noise suppressor in the loop a while ago but for some reason wouldn't allow any signal through even on bypass, the hum is so bad the threshold of the NS would have had to be so high it would kill the sustain of the bass anyway.

You'll like it less when they blow & you have a big clean up to do & the possibility of other knackered parts. I was quoted £80 to get mine done in a Hiwatt.

There's an amp-tech up near Dunfermline (Dennis Marshall - no relation) who was a SC collector. He's very good, worth a chat with him at least.
