rocks66ss Posted December 23, 2020 Posted December 23, 2020 I have a a Gibson Scout amp my dad bought me in 1966. I have replaced some caps and that is about all with the exception of a tube. My issue is the reverb. When I click the reverb pedal, the reverb is on, but I can turn the reverb pot and nothing changes until I get to about 7 and then the volumn of the reverb drops down some, but there is no change what so ever from 0-7 and then drops a bit. The schematic shows a 2 Meg audio taper pot. do you think it's the pot or something else? A 2 Meg audio taper pot seem very hard to come by, if the concenses is the pot, what might be suitable as a replacement. Thanks Rocky Quote
Cam in alberta Posted December 25, 2020 Posted December 25, 2020 not an expert but the pot sounds like it needs cleaning. or replaceing Quote
rocks66ss Posted December 25, 2020 Author Posted December 25, 2020 I've tried cleaning didn't help. I'm having a hard time finding a 2meg audio taper pot. If anyone can tell me what difference a 1meg audio taper pot would do. There are a lot of those available. Rocky Quote
badbluesplayer Posted December 29, 2020 Posted December 29, 2020 Prob not a pot. Sounds like the reverb circuit isn't working. Maybe a bad connection or maybe a bad tube? Quote
rocks66ss Posted December 29, 2020 Author Posted December 29, 2020 I have switched out with several different tubes and it still acts the same. Quote
PDH Posted May 1, 2021 Posted May 1, 2021 (edited) bad tube or tank connection Edited May 1, 2021 by PDH Quote
