This preamp has been mentioned now and then on the BG side, but not over here AFAIK.
I took a chance and bought one online recently. It needed a repair because the dual transistor input stage had been partly cooked. These original parts are now essentially unavailable, so I grafted in a pair of the JFETs recommended by Francis deck for his 'quick and dirty' preamp. The result is great, and my unit is now fully operational.
Here are the main things I love about this device:
- IEC mains connection, no batteries or wall-wart
- 'mic in' with 48V phantom, polarity, 80Hz hi-pass,20dB pad, selectable impedance OR
- 1Mohm 'instrument in'
- 3 band fully parametric EQ
- XLR and 1/4inch outputs
it also has balanced effects send and return and a
compressor (selectable before or after EQ), although these were not a high priority for me.
The mic and instrument inputs have a 'saturation' control which I doubt I will use.
I have tried the Eureka out with the e906 and the Audix M1250B mics on my bass so far. The impedance selector has a nice subtle effect on the e906 tone.
Many reviews mention the small controls on the front panel, and they can be a challenge for my big hands. I put a strip of tape on the top of the unit and drew a guide to which dial was which, this has helped a bit.
