I have developed a huge gas for an Octavia pedal lately and I also got this sound in my head that seems to be nailed by the Chicago Iron Octavian from what I can understand by listening to Youtube videoclips. So I begun to search for one and they seem to be quite pricey. Worth to spend the extra money? There seem to be two types of their Octavia pedal ,one called Octavian with a led and mxr type knobs and one called Octavia with no led , different knobs and Tycobrahe printed in place of Chicago Iron. Are there any differences between them besides the cosmetics? Additionally my search of this company led me to check out their other pedals too and they also have a wah pedal that is even more expensive , is it that good?
