I wanted a reverb pedal for a drippy '60s surf music sound. After seeing several video reviews, I settled on the Oceans 11 from Electro-Harmonix. This pedal delivers! Lots of other reverb effects, and tremolo too. A little pricey, but worth it for my applications. I like clean and twangy as I do 1950s and 60s music. I don't use much distortion. It worked wonderfully with my cheap Silvertone practice amp. I also have a Line 6 Spider IV modelling amp and the effects were less pronounced. I think the Line 6 was muting some of the Oceans 11 reverb effects. I believe some tweaking on the Line 6 amp will fix that.
