Curious how this thread keeping coming back, like an echo.
I use a couple of delays: MXR Carbon Copy and a Dano PB&J. Bung the CC in an effects loop with a lot of preamp overdrive and you get a wonderful warm 80s lead tone. Used between a clean guitar and the amp it sounds fat & lush. The PB&J does a nice digital delay, all clean and snappy, and has a second footswitch that halves the delay time for rockabilly slap-back sounds.
No tap tempo but lots of good tones from those 2.
Ha ha ha ha!
I took a Carbon Copy for a little while and really liked it, but I couldn't justify the incremental cost when I already had a Hardwire that did a decent emulation and the Carbon still ate batteries like chocolate.
I was / am looking for a delay that is as stingy on batteries as my Keeley Compressor.
