i have a fender hot rod and its great but when i looked in the manuel something puzzled me. now the tubes in the hot rod amps are color coated: they're either white, red or blue. in the manuel it says mine should have white ones but mine has blue ones? it says that when replaces the tubes you should replace with the same colors or you might have to adjust the tube bias. what should i do? im confused
when you get new tubes just put white ones in... i guess.
yeah but idk if the amp is set for the white ones or if the manuel is wrong and its set for the blue one.
be safe, bring it into your local music shop and have the tech guy take a look. they know what they're doin, its their job
