I posted a thread earlier about some questions on the fulltone bass driver, i just wanted to go ahead and thank those who replied. So i bought one used, great shape though, and it didnt come with a book or any information. So i want to know if the boost knob only has an effect when the boost is activated or if not what it does. Also any settings people want to share would always be welcome. If anyone uses and SVT-Cl that they use it with that would be even better cause i use that head with a sterling HS.
