to answer a bunch of questions....
ALWAYS put an overdrive infront of an amp. Putting it in the loop doesnt sound very good, and could damage some poweramps.
YES it will work with SS amps, effectively increases your gain and tightens your amp.
true bypass DOESNT MATTER with 808's. This is because they use "buffered bypass". In otherwords, the input is high impedance, because the power starts at the jack, essentially increasing the voltage of your signal to carry it through the effect without losing tone when the effect is disengaged. That way the low impedance that the effect causes is negligable because of the buffer.
