The problem with running a compressor in the effects loop is that you're blending the compressed signal with the non-compressed signal, in effect,

It depends on whether the effects loop is series or parallel. A large percentage of bass amps run it in series such as my GK-800RB. If there is no Blend or Mix control, it's series. That means it is just fine for a compressor. The SWR SM 400S has a series effects loop.


If it is in series, it is an insert, it isn't a loop. Effects loops are parallel and blend the effects signal with the original or "dry" signal. The fact that the signal has two parallel paths is why they call them loops. In a series arrangement, there is an input and an output, there is no parallel path and no loops. Inserts are series Effects loops are parallel. The terminology is sometimes confused, but they are two entirely different animals and it's misleading to call an insert a loop or vice versa. Not knowing the difference is why musicians plug a compressor into an effects loop and wonder why they can't get it to work.


Manufacturers call series F/X loops "F/X loops" all the
time. Yes, it's just a "2 TS jack" insert as opposed
to a "1 TRS jack insert"

I have specifically seen the terms "series/parallel" as
Jim uses it in product literature.
