I do have the DR-05. I typed the wrong number, and now have corrected it. Thanks.
I also have a DR-07 somewhere. It is smaller and may not still be available.
The DR-05 can be powered by USB, in addition to batteries.
Haven't tried the audio recorder on board, but the mic input and reverb are very good on the EA-7. Wish it had a harmonizer.
Also, I learned something today. I have a number of lead sounds in my "Favorite Sounds" bank. They are saved with the editing and effects in place at the time. However, if you have a OTS engaged (lit up), then call up a Favorite sound, if you have not exited the OTS (turning the light off), it retains the effects of the OTS.
That's why the Growl Sax sounded wrong to me. It wasn't using the effects I expected.
Thanks guys; it is a work in progress!
