Best For Use With Bass Guitar: Line 6 Helix Processor

Buy on Amazon

Next on the list, we've got yet another processor that manages to win our hearts. It's the line 6 helix processor and it's widely considered as one of the best convenient processor you can buy. This pedal is pretty much a one stop solution for your pedal needs. It is equipped with eight capacitive-sensing footswitches with color-coded led rings, and six led scribble strips that facilitate fast and intuitive effects selection and editing. It is a 'virtual lightbulb' that mimics the decidedly nonlinear behavior of the small incandescent bulb and four photocells inside the original shin-ei uni-vibe pedals that are essential to their unique sound and vibe.

With an expression pedal it covers all of the bases for a guitarist. It has 2 separate outputs, one for bass strings and one for all others. It can be used out of the box with pre-installed firmware. This would be ideal when using it with an acoustic-electric guitar or something that doesn't always require an amp sound.

Why We Like This:

Awesomeness in a box and an ease to navigate
You can also use onboard 14" jacks to control amp switching
Acts as the command center for your entire amp and pedal rig
Capacitive-sensing switches with led rings and scribble strips

Best With amps: Zoom FX Loop

Buy on Amazon

The zoom fx loop gives the top-tier processor a run for their money by offering flagship specs at a much more affordable price. This multi function pedal has lots of options for effects, and the knobs allow you to adjust to effect level, tone, and other tone elements varying by effect type. It includes 68 built-in rhythm patterns which enables solo performances and makes it the perfect practice rig. You can use these patches to emulate the iconic sounds of eddie van halen, jimi hendrix, and carlos santana or explore something completely brand new.

The user interface to create chains, add effects, and make other changes does have a learning curve just like a video game controller or smartphone. It's very easy to "slide" the virtual stompbox chain over to get to and control the effect you want using the switches at the very bottom. There's no dedicated volume knob but all the levels throughout the effects chain are programmable and savable and recallable. The expression pedal can also control volume, drive (overdrive), vibe, echo, reverb, delay, phaser, and pitch. The ease of creating unique patches is great also.

Why We Like This:

Great build quality, and tons of solid effects to work with
Easy to set up the effects order and dial in the sound
Delays are nice and clean, the looper function is a nice plus

Best touch screen: Zoom Multi FX Processor

Buy on Amazon

We would, of course, be remiss if we didn't mention zoom multi fx processor for daily usage. If you are playing one bass, it’s a great kill-switch to go silent. It’s like having a closet full of different effects pedals, amps, preamps and speaker cabinets. Separate inputs allow you to switch from electric bass to synth or acoustic bass, and back again. It’s got switchable input impedance, good sounds, good bypass, a very usable tuner and hits a lot of what you could want to get many different sounds possible from subtle to in-your-face.

The touchscreen is only usable when it is sitting on a desk next to you, and too much reliance is put on the touchscreen for navigating. The touchscreen and the versatility of the editing of effects and effects chains is awesome,being able to move slots around with just a swipe makes it easy to see how one effect affects the next and you can tweak the sounds to your particular instrument.

Why We Like This:

Great midrange multi-effects and practice rig
Lots of great tones and features
Very easy to bypass everything or just the effects
Colorful on the dark stage floor
