Re: Effects Question
The effects loop taps your signal between the preamp out and the power amp input. Placing certain types of pedals in the loop versus in front of the amp may have a positive or negative impact on your tone, depending on the type of effect and whether the loop is series or parallel.
Conventional wisdom is that effects that shape your tone (wah, compression, overdrive/distortion) should go in front of the amp, while modulation and time-based effects can go in the loop. But just play around and find out what works best for you.
