I got the Science Amps/Electronic Audio Experiments collaboration Mother Preamp Pedal.
I used to have one of Science's Mother Amps which this pedal is based on. A 200 watt monster with KT88s that was sorta based on a Hiwatt. A great amp that I am a little sad I got rid of, as it was excellent for bass and guitar. I was starting to consider buying another, and then they released this pedal, so I decided to see if this would scratch the itch.
I put it in front of my main amp (72 Orange OR120) and it quickly replaced an always on pedal I had on the board. The "A Channel" on the Mother pedal dialed in with low gain adds just a little hair on my clean sound and it reacts real well with the amps natural character when I strum hard and settles down when I lay off. Really gets the sound I want without having the amp loud-loud. The A Channel stacked with the EAE 0xEAE Boost is gnarly and rules The B Channel on the pedal offers a real nice distortion sound (can dial this to be just past crunch to a nice warm thick distortion) which you can push to be louder than the A Channel if you want to use it as a boost. Stack that with a Muff style pedal and get out of the way.
I also tried to pair the pedal with a solid state poweramp (SD powerstage) and while it loses a little of the tube amp characteristics, the essential sound is still there, and if I were to play a fly in gig, I'd be 90% happy with the sound into a borrowed cab.
Still haven't played around with it on bass yet, but I'd be surprised if it wasn't excellent there as well.
So yeah, I spend $300 on it and now I don't feel I need to buy a $2500 amp.
