sao Posted February 10, 2013 Share Posted February 10, 2013 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) Ta.

Jack Posted February 10, 2013 Share Posted February 10, 2013 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. Quote Link to comment Share on other sites More sharing options...
sao Posted February 10, 2013 Author Share Posted February 10, 2013 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.

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.
