I posted this first over in the "Effects" forum but closed that thread as I now think it's more appropriate here... I'm really interested in a clean, simple, pedal-sized 9v supply powered headphone amp to use at the end of my effects chain for silent practicing. No cab sim, or the option to turn off a cab sim, is very important as I'll be using it with both both my bass and guitar pedalboards. I've narrowed down my search to three similarly featured and priced pedals - the [Invalid or Expired Link Removed], the Invalid Link Removed, and the Saturnworks Headphone Amp - and want to know if anyone has hands-on experience with any of them. Before anyone suggests it, I'm not interested in the PJB BigHeads or the Ashdown Tone pocket because of their respective formats, costs, and power requirements.
