After I repaired my 1968 Fender Vibro Champ (with lots of help from forum members (you know who you are, thank you) I now have a large amounts of headroom on my amp that takes pedals very well. I prefer 5881 tubes over 6V6s. What I did was change the cathode resistor and cap with a 490 ohm 5 watt resistor and a 20uf 200 volt capacitor, install a 5V4 rectifier tube (slower ramp up) and add a 5881 tube. This amp has a beautiful blackface clean tone that sounds like a low power Twin.
