Hi all ive read quite alot of threads regarding best locators and all and heard first hand of the barryvox and ive used the bellman a few times which where great to, right up till the end of this year ive still personally been using the old knocker box as the sets all around here are easy and shallowish. Long story short was looking into buying the orvotox d1 not too expensive and sounds ok does anyone use them???
