I've been asking a lot of questions here but this is my final ones.

These are my questions:

1. Is the SD Blackout bridge like an EMG 81 but with a little more bass response?

2. Can, for example, the Dimarzio x2n or D-activator x provide heavy tones like the EMG'S OR Blackouts can. I would really like to have passives as theres no battery and there less expensive.

3. Will a low watt tube amp give me a tube sound/tone overall.

You answered #3 yourself.

This clock is opening another door
if u get a low watt tube amp itl give u a similar sound but not quite the same, unless its a really good one which is really nearly as expensive as a high wattage tube amp
