I know this is not really the right palce for this, but I can't find anything on the web and you guys seem to know what you're talking about.
I have a Blackstar HT-Dual and new Vox Straight 6. They are both Hi-Voltage tube overdrives, running off low voltage with a step-up system.
I didn't realise until recently that replacing tubes meant having to check/adjust the bias. Is this not necessary on guitar pedals? It seems like it would be necessary but nobody on the web seems to mention it as far as I can find.
