Doug's Revibe Question

[TIMBO]

Hi guy's, Can Doug's REVIBE be used as is in a passive FX loop or is it an upfront FX. What is the difference between vibrato and tremlo and what about using a 6AQ5 instead of a 6V6 in the reverb. Thanks

... What is the difference between vibrato and tremlo ...

Tremolo = variation of volume
Vibrato = variation of pitch

... what about using a 6AQ5 instead of a 6V6 ...

Different socket. That's about it.
