Back On Topic.
I've been using the Red Eye for the past few months and I'm very happy with it.
I use it thusly: Juzek w/Spiro Mittels/B-Band D-1 Pickup/Red Eye/WalterWoods Electracoustic/DIY 12" Eminence speaker cabinet.
I've used it in drummer-less, and drumm-ed Trios and Quartets - NO PA or FOH ever. I'm fortunate to play with very sensitive/tasteful/thoughtful Drummers. Thank DOG.
It does a nice job of slightly warming up the pickup, though the B-Band D-1 is not a Piezo, but is an Electret film.(Don't ask me for a technical explanation! It is not as "squawky" as a Piezo, IME.)
My Juzek is NOT an Orchestral Decibel Cannon, but it is very even across all 4 strings, (and registers), which is very helpful when amplifying, IME. Spiros sound warm and FULL, even with the bow (unamplified.) (I don't play much Arco/Amplified.)
The Red Eye sounds very good with the WW almost FLAT - I take a small amount of Treble off on the WW, and keep the Bass nearly flat...I prefer a warmer/darker amplified sound, and want to avoid the thinness of some pickups...(you know who you are.)
I have used it at only moderate volumes, and have no idea how it would perform at Stupid Loud Levels.
I don't use the Boost function at all.
It's nice knowing there is a Direct line out, as the WW does not...(I've usually used a Countryman DI box, when necessary.)
I no longer feel the need for the FDeck Pre in the signal chain, but that might change if I ever needed to get Stupid Loud. FYI.
So, it is in the permanent Signal Chain, for now. Great Product - UnderPromise/OverDeliver.
Thanks.
