Guest MoJo Posted December 11, 2013 Share Posted December 11, 2013 I love the growl of my TB500H but am less than impressed with the ineffectual EQ in the preamp. I've got a Boss GEB-7 heading my way but I'm unsure whether it should go in front of the preamp or in the effects loop to get the best out of it Quote Link to comment Share on other sites More sharing options...
pete.young Posted December 11, 2013 Share Posted December 11, 2013 In front. Guessing that like most amps, the effects loop will be parallel so you will only be EQing half the signal. Plus the loop will be looking for a line level device not an instrument level device like your GEB-7. Quote Link to comment Share on other sites More sharing options...

Billy Apple Posted December 11, 2013 Share Posted December 11, 2013 I read that the effects loop is for rack stuff, and not pedals (of course cant find the link now), for whatever reason pedals cause distortion. I'd want to EQ the clean signal. If you EQ post, then you are kind of EQ'ing a muddied tone Quote Link to comment Share on other sites More sharing options...
RandomBass Posted December 11, 2013 Share Posted December 11, 2013 If I remember rightly the effects loop is serial - as are most amps I thought. However, the effects level is darned high on the TB500 - you will be better off putting it between the instrument and the input. Give it a try either way, and see which works best for you.

An effects loop should be either series or switchable. I can't think of a single instance when parallel only is more useful. Quote Link to comment Share on other sites More sharing options...

[/quote] Markbass are parallel by default, switchable with a jumper inside the case. I assumed that most amps would be done this way, but it seems that I'm wrong, and that series are more common. Apologies. From the circuit diagram it looks like it is indeed a series loop. The point about the line level signal still stands. One reason given is that, even if something fails in the loop, you still get a noise coming out. Another reason is that it may allow to you blend the clean and effected signal, something which some older effects units may not offer.
