Aloha, hope all are well.

I picked this amp up today off Craigslist, sounds great, but as this is my first Marshall, I wasn't sure about this loud hiss when I kick in the second channel.



The Classic and Ultra Reverb knobs don't appear to have much of an effect either. Stuff online says it's usually the preamp tubes, but I went through all that with a Traynor amp I bought a little while back, replacing the the tubes in that didn't fix the reverb.

Thanks
