I have a Peavey Max preamp that I'm not really using right now. It has two channels (solid state with graphic EQ, and tube channel with rotary control EQ). The channels can be switched or even combined via a footswitch which maximizes the tonal variations that this thing can do. This is a perfect front-end piece to a live rig featuring separates. I have played it live (with tube channel) going thru the power amp section of my Ampeg SVT3 Pro and it sounded like my Ampeg except maybe just a bit cleaner. it also has the ability to go dirty overdrive with the tube channel if you're looking for lots of character or just warm and present. The 3-button Peavey footswitch also has EFX in/out which is pretty neat as well. The part number for the Max foot switch is 00078470 and the list price is $43.79 I upgraded the tube with an Electro Harmonix gold pin 12AX7 which didn't make a lot of sonic difference compared to the factory Sovtek (EH's are just premium Sovteks after all, I guess I had a good one to begin with). I bought this used from a music store for recording and sold my Sans Amp BDDI after because the Peavey just sounded better. Why have tube emulation when you can have the real thing. This preamp will take you from Geezer Butler overdrive to clean and glassy scooped slap EQ and everything in between. I bought it for recording but realilzed I really wanted a channel strip with built in compression and mic preamp for vocals. I just bought a Focusrite TrakMaster, so the Peavey is now available. As is typical for this type of unit, there is a tiny bit of tube hiss which makes it difficult to use in a recording situation, but it's not even an issue for live work. That's why I went with the TrakMaster. If you do a search, you'll find a few rabid fans of the Max preamp here on Talkbass. Price is $175.00 US plus shipping from Guelph, Ontario, Canada N1H 1C5. It's just a neat piece and for what it does I might just keep it as a backup to use at a big gig if I need multiple cabs and a power amp. But so far it's just sitting with my home studio stuff. Here's a pic of the actual unit. It's got a few scratches but functionally is a 10.
