Have an amp with effects ( LIne 6 III 75, Roland Cube 60 )

or have an amp without effects and have a pedalboard?


i'm in that dilemma

because if i have an amp with effects
how could i change them, without using the amp, (moving the amp)
in other words use other things to change the effects like using a pedal


or have an amp w/o efffects and have a pedalboard or multi-fx


Explain me please

Generally (though not always, it depends on the effects being used), individual pedals will sound better than built in effects or a multi-effects unit. If you think that you will be gigging with this amp in the future then get one without effects built in, so that you can switch easily during songs without having to stop playing.

What's your budget? What styles do you play?
