I had a Yamaha PB-1 that I had in front of a Crown DC-300 poweramp into a couple of cabinet configs, sometimes 15"/18", sometimes 8x10. I had that rig from 1984-2004. I donated the rig to a local school in 2004. I'm glad I did but I really wish I had that Yamaha PB-1 back.
The Yamaha PB-1 is a absolutely fantastic preamp. Sounds great, can dial in some great tones with the parametric EQ. Can adjust both the frequency and the affected range (is that called Q?). In the mid 90's a friend used my rig in the studio and recorded both mic'd and directly from the Yamaha. The bass tone sounded great on the CD.
Little off topic. I say I want the PB-1 back but I don't know if I want to go back to amp/preamp and big racks. I like having a smaller 10-15 pound all in one. PB-1 by itself was 11-12 pounds, the DC300, jeez, it felt like it weighed a ton, with all the other gear I think the rack was pushing 60-70 pounds or so. I know amps are lighter now but with amp, preamp, rack, and any other gizmo in there I still think a rack-job would still be around 35-40 pounds minimum, compared to some all-in-ones 10-15 pounds. OK back on topic.
Even if you choose another preamp, I don't think you would go wrong by spending another $150 bucks or so on a used PB-1 to keep in the stable. I think I just convinced myself to scour craigslist and see if I can get a PB-1 to keep around, just in case.
