Greetings. I just inherited a 1964 Fender Super Reverb (blackface) from my aunt and need some advice on what to do next. The normal input works fine and sounds great. The tremolo input however...the vibrato doesn't work, the reverb doesn't work, almost no volume and no top end. Sounds bassy and you can turn it up to 10 and still barely hear it. At this point I should say that my aunt is the original owner and the amp mostly just sat unplayed for years and years so the thing has its ORIGINAL set of tubes (RCA power tubes and the rest are Raytheon branded). No joke. So my question is this: So baring in mind that the normal input is fine and the trem input is not, is there something obvious that sounds like the problem here (like new tubes?), OR is my best bet to find a tech and have them go through it? The only thing I've done is replace the cables to the reverb tank because they were broken. ANY help would be appreciated!!! THANK YOU!
