Best Overall: Line 6 digital Effect Processor

Buy on Amazon

The line 6 digital effect processor is capable of outshining several other processor featured in this list in overall features. Sound-wise it sounds amazing (just like a helix family product) and even though it has a limited amount of dsp you can pretty much use every effect you'd like. The tone coming out of this amp is amazing. It also has a virtual pedal you can use on the POD Go directly without an external pedal. The use of the camera adapter kit on the ios device disables the volume control on your phone/ipad so you get very loud to the point it drowns the guitar or damages your ears.

With those added, this is a five star pedal, and will be the best pedal for any amateur guitar or bass player, IMO. It has a smorgasbord of high quality tools/effects and it is also fairly easy to figure out and start dialing in your own presets right away. The sound and overall feel can be summed up in one word,professional.

• Sounds like a helix, simple as a pod
• Very user friendly / performance friendly
• Can be used as an audio interface
