Sqeal on SS-20 lead channel?
« on: March 29, 2016, 12:35:47 am »
Last night I was playing at the lead channel, tweaking a lot so I was playing around with gain from 9, 12 up to3 o'clock. Some times I would switch to clean channel and use my Fulltone PlimSoul and back to lead (plimosul off). At some point after going back and forth channels and changing gain values I increased gain from 9 am to 1 pm the preamp started to squeal, very bad. So I had to keep my gain at 12 to avoid the squeal.

Have you ever had this problem? What are the common causes and ways to avoid it?

Not sure if this had anything to do to fix it but last night I opened the preamp and took a look at the tube to be  sure it was not loose, it was not but anyway I kind of gently pressed it against its socket and put it all together. So today I unpluged every other pedal and just guitar -> preamp -> power amp and no squeal. Plugged everything and no squeal. Normal floor noise level from the lead channel, no noticeable noise from clean or crunch so all is ok now.
