Looking for a lot of the guitar sounds that were on countless songs that you heard in the 90's and before? Looking for a pedal that you can take with you AND your portable powered amp? I used one of these years ago when I'd practice on the way home from working in Aspen because I didn't need any more wires!

Here's what Boss sez about this unit:

The ME-33 Guitar Multiple Effects arrives with an incredible range of killer 24-bit BOSS effects, onboard COSM Amp Modeling, and Quick Edit knobs for fast tweaking. Throw in an onboard expression pedal and new EZ Tone feature and you've got the easiest way to tap into a tonal powerhouse.

• Floor-based guitar multi-effects processor with 24-bit sound quality and built-in assignable expression pedal
• Onboard COSM Amp Modeling with 6 distinct guitar amp models plus simultaneous overdrive and distortion effects
• 6 Quick Edit knobs for instant, familiar effects tweaking
• 24 distinct guitar effects (9 simultaneous) including new Feedback Modeling, Auto Wah, Humanizer, Harmonist, Auto Riff and Phrase Trainer
• EZ Tone settings for fast access to tones from a variety of musical styles
• Acoustic Guitar and Pickup Simulators for instant acoustic sounds
• Large backlit LCD with helpful operation graphics and icons
• Built-in auto tuner and patches optimized for use with 6- and 7-string 

This really is a good pedal for the money. And VERY portable when all you have is a aux input on you car stereo! Practice where ever!

Comes with self printed manual. Batteries in it now are new. You'll have to get a 9V power adapter to plug it into the wall.
