Description

Edit description

Purpose built to give you more of your instrument and amp, the OD-503 enhances the drive and natural harmonic content of your instrument, effortlessly giving you even more of what you already have and love!

With its extraordinary dynamics and immediate feel, the OD-503 responds naturally and cleans up beautifully with either your pick-attack or your guitar's volume control while adding that "extra something" that makes your rig really sing.

Three simple controls, matched impedances, true-bypass and daisy-chain friendly "industry standard" 9VDC power make mating the OD-503 up to your setup a quick and satisfying affair, and when that red light kicks on the riffs begin to flow!

Every OD-503 is entirely handmade and built-to-last by real people right here in Portland, Oregon, using exclusively premium, top-grade components to ensure superior tone and years of dependable performance.

Mr Black OD-503 Dynamic Amplifier Overdrive | Delicious Audio

delicious-audio.com

Mr. Black's OD-503 is a handmade low-gain overdrive that excels in enhancing your guitar's natural tone without overshadowing it. Its dynamic responsiveness and ability to clean up with your pick-attack or volume control are standout features that give your rig a vibrant edge. However, the simplicity of its three controls may not cater to those seeking extensive tonal versatility. While the build quality and premium components ensure durability, some players might find it lacks the punch needed for heavier genres. Overall, the OD-503 is a worthy addition for those looking to amplify their sound's essence, albeit with some limitations.
