QUOTE (Marshmall0wz @ Aug 21 2008, 10:28 PM)  I was wondering whats the point of an fx loop instead of just putting pedals and stuff straight into the amp. Ive also heard the amp can be used as a boost. ANDREW C.! Here's a question mainly for you or other knowledgeable moderators  I recently read something about reversing the fx send and return levels when using and fx loop...im confused on this issue heres the direct text from BUGERA AMPS. "The FX Send Level and FX Return Level controls should always be set oppositely. For example, to reach a 0 dB working level when the FX Send Level is set low , the FX Return Level needs to be set high accordingly. On the other hand, if you wish to boost the volume level, turn both controls to a higher setting."feel free to dive in thx GMC Regarding the levels - it depends what you want to achieve. What this is trying to say is that overall, to keep the gain correct, the FX in the loop should neither boost nor cut the level at that point. YOu use the pre to get a good level for whatever effects you are using, then adjust the post so that it cuts or boosts the effected level back to pretty much the same level it was before the fx loop, that way you won't alter the gain characteristics. The final part says however, that you can use the FX loop as a boost and get more gain into your power amp stage if you turn them both up. -------------------- Check out my Instructor profile

guitar ---> effects ---> preamp ---> fx send ---> effects ---> fx return ---> poweramp ---> speaker
Simply, putting effects before the preamp gives one result, putting them in the fx loop another. Which sounds better is up to you to decide, or your audience. Trying to keep a picture of the signal in your head makes it easier to understand what you're getting in the end. If you're using a delay effect before the preamp (with distortion) it will distort the delay. Using the delay in the fx loop will add delay to the distorted signal. (I prefer to use the delay in the loop) When you're drawing this picture it's helpful to know Effects alter the signal Preamp scales up the signal from the amp input Poweramp recieves the signal from the poweramp or the effects loop if it's used and scales it up to your desired output An effects loop can be serial and that's what you see on the top line. A parallell loop will split the preamp signal in two parts and then mend it together before the power section. If you have a parallell loop and several amps you could connect the fx return into another poweramp (fx return) The dB switch or input/outpur rate of the fx loop could, simply steer the signal strength of the signal you send through the loop. Mind that if you're running the signal (from fx send) through a device that's fed with instrument level signals you might want to make sure the signal isn't unbalanced going in (from the fx send) but raise it after the preamp and before it goes to the power section of the amp. A dB switch scales it down over at the send side and then scales the signal up again over at the return side. ...I'm confusing myself. Preamp signal -> fx send -> level cut 10dB -> effects -> boosted 10dB -> poweramp And then what you said, if you can turn both the fxsend level and the fx return level up to 10 both of them you'd get a boosted signal allright. -------------------- My bands homepage

Holy $#!+, screw effects.
 The spring reverb on my amp, tuner, od, and wah are the only effects I will touch for now. All this is confusing me.

I got myself a Loopmaster true bypass 4-loop with tune out thingy for my pedalboard. So all I do now is plug the pedalboard cable straight into input. Aaaand done.
