hello all. Just got a new laney lc15r today to replace my hunk of turd peavey. Just worried/pi55ed off about a few things. Firstly after a while the amp sounds like radio static like a loud whoosing sound, thats when its fairly cranked. secondly i have a digiverb im using in the fx loop and it was weird because it worked fine when i first tried it but later on whenever i turned the reverb on the pedal the tone from the amp was completely altered like it became really hollow. When i turned the pedal off the tone came back. Im also using a boss delay which works fine. any advice would be great cheers
