Question for other SC20 owners; as I outlined earlier, my Low Sensitivity input is VERY quiet. So quiet that that if I dime the preamp gain and master volume in full power mode, it would have a hard time competing with even a mild drummer. This is based on using a 'standard' Telecaster, so single coils, no magic. If I clean boost the hell out of it I can get the volume to a degree, but I'm wondering whether this is intended. As it happens, I'm happy on the High input, but it sort of confuses me a bit. Obviously there are no schematics (available) for the SC20 yet, but looking at the preamp section of any JCM800 dual vertical input models, it seems that V1B is the extra gain stage for the High input. I'm going to try swapping the valve in a bit to see if V1A is somehow "impaired". If this is normal, has anyone got any tried and tested methods for bring the signal level up a little on the low input? Obviously swapping out the resistors isn't rocket science, but I'm just curious.
My Low input is a lot quieter too, but I hardly ever use it anyway.
