The king of effects boxes is the multi-effects pedal. These are available in all flavors from basic to complex. And by complex, we mean chaining so many effects that your guitar doesn’t even sound like a guitar anymore. These monsters can replace a whole truckload of stompboxes that tend to end up in your gig bag all tangled together (when they’re not busy chowing down on 9-volt batteries).

From the awesome folks at Sweetwater: Guitar Pedal Buying Guide

A Bass Player’s Dream Come True. The BOSS ME-50B puts world-class bass effects in a rugged floor unit with easy pedal-style control. Effects are divided into six sections—Compressor/Limiter, Master, Filter/Tone, Drive/Synth, Delay/Modulation and Expression Pedal—giving bassists a range of unique and powerful tones including new effects like Sound Hold, Octave Up and Kick Drum. Effects can be edited using 23 knobs and controlled via three built-in footswitches and an assignable expression pedal. This is the piece no bass player should be without!

  • Floor-based bass multi-effects processor with easy analog control
  • Killer COSM® Compressor/Limiter and Drive effects, plus T-Wah, Slow Gear and Defretter
  • Innovative Sound Hold function for sustaining a low note while playing on top
  • Sound On Sound recording with new Kick Drum effect for keeping time
  • Dedicated knobs for each effect section—no menu-surfing!
  • Easy Tone effects with Preset EQ templates for quick tone editing
  • 3 footswitches and onboard expression pedal routed to 6 options like Octave, Wah, etc.

So many knobs!

Lots of knobs to twiddle, but it's all pretty well labeled and easy to figure out. The one thing I needed a manual for was the expression pedal--it wasn't obvious to me that you need to push on it with your toe for a moment to activate the interesting expression-pedal functions.

I'm not an expert, but the results sounded pretty good to me.
