I got the dual Di box they make for recording the Clean Di and original Amp sound at same time and does seem to work well on occasion for what would seem to be random events it can very noisy with its thru connection to the Amp.
I've just ordered (as trying things out as affordable as possible) the Art Dual RDB Re-Amp box it seem like the tool for the job was wondering if anyone has used it?
I'm aware Countryman and Radial make the preferred re amp boxes for doing this 🙂
I have almost exclusively used my DualRDB to attenuate "tape out" from a mixer to patch in to my Zoom H2next mic input - does the trick. Brings the signal down from effectively line level to mic level (or instrument).
