Which preamp pedal should I buy?

[4Mal]

in my recording arsenal..
Sushi box Underground Accelerator
BBE BMax T
Rane 5 band parametric EQ - great clean preamp!
HX Stomp
HX Native (highly recommended)
Ampeg PF- 20T ( yes, it is a 20watt tube amp but it can run silently without a cab amd is greaking awesome!)
GK Mb-200 (another amp but can run without a cab, cops a very good RB-800 sound)

Attempting to add...
Sushibox Nobelium
Avalon U5 (for like the 5th time...)

Would add if I found a "can't pass this up deal"
Ampeg SVP
Demeter HPB

Nothing on your list would get me excited. I've had much of it and sold it. The Tone Hammer stuck the longest... You can often find truly great rack mount pre-amps for not much. Who carries racks anymore ?

My 2 cents? I have chased that pedal for years now. What I ended up keepig was, the Darkglass Alpha Omega because of the DI. My Rusty Box, the limited one that is Grey and Black with orange knobs, man that thing is awesome!! Then I got me the MBD (3), it is also a keeper. Of course these are for mostly Metal, or some kind of noise rock. Try listening to the samples of each one on YT.
