substitute for a pre?

    by making and buying various distortion, overdrive and fuzz boxes some if not all with tubes in them could you use that as a preamp?

    also if you wire your bass straight to the output (i think its called hotting the pups) can this damage the tubes or pedals or even the amp?
  2. Some pedals, e.g. a zoom b?? 708, come with a gain control, so that you can ensure that your signal into them is at the right level for optimal processing. They also may have an output level control.

    In theory, you could drive an amp directly from that, if you knew that the input sensitivity of the amp was compatible with the output level of the pedal.

    In practice, many pedals have a gain of about 1, i.e. you get out the same level that you put in, and that would not be enough to drive a slave amplifier with a say 0.7 volt input sensitivity (0dB).

    If you mean taking a feed from the pickup straight to the amp input, then no, it will not cause damage, but it might not be very loud, and it might be distorted due to impedance mismatching.

    BTW, posting the same question on two boards is frowned upon.
