Look at Ron Sunshine on you tube he uses that delay pedal all the time. I think it sounds ok but I'm not a effect pedal guy. I prefer to play clean I don't even like to use amps anymore. Just right through the PA but thats why Baskins has 51 flavors. Try it you may like it.
Here is the link for the English Tombo site in Japan, you migh be able to order from them directly or, perhaps one of their international distributors (see link at the left side of their page) is near you.... Also a lot of European resellers carry Tombo, so checking with one of the (European/British) on-line shops might solve your problem...
I'm looking for someplace I can purchase 3 harmonicas made by tombo/japan. they are the Ultimo #1810 the aero reed #2010 and the folk blues #1610. All sites online I find them the language barrier kills me with the exception of Australia that wants $90.00 for what Japan sells it for $39.00. Anyone know of English site, reasonably priced tombos. thanks
