Greetings, I'm very close to delivery of my new Sei Bass singlecut 5-string (see my thread in Basses). I've speicified custom-wound Kent Armstrong pickups (effectively MM+P) and the John East U-Retro preamp. Now, I've played basses with the U-Retro or J-Retro and loved the variety of tones on offer, as well as its versatility (sweepable mids, etc). I've also decided on it because John East is fairly local and I hear he's OK about making modifications to his preamps to his customers' tastes. So, I guess I'm just interested in anyone's experience of the J-Retro or U-Retro in comparison to other preamps out there - just hoping I've made the right choice! Russ
Yes, the new ones are much quieter and the old ones can be retrofitted with the newer chips. There is a huge difference after the upgrade.
You have trim pots inside, so you can reduce the power to match your pups and personal preference. I have both a J-Retro (with Fender CS 60's pups) and a U-Retro with Bart MM+J, and love both. My next active bass will have U-Retro Deluxe.
