Hi

I've had some problems with my amp lately. It's a Sound City 50w tube amp, very similar to Hiwatts, but I think this problem applies to all tube amps.
The sound is really bad. The volume hasn't decreased but it's like someone's put a blanket on my amp. It's lost most of the top freqs and it distorts even at low volumes. I get some popping noieses too, like when you touch the tip of a jack when it's connected.

Any ideas????? Is it the tubes or anything else?

Thanks

It could be dirty. You probably need to have a tech clean, and re-bias your amp. You may need new tubes, also. Basically, a tune up. Probably $100.00 for the labor, and more $$$$ for the tubes. And don't try previously used tubes. Get new ones.
