Honestly don't know why I am listing this. I guess I am in that weird place to try something different. Since i don't have any money to buy another preamp right now this is the only way. Ok for starters I want to say I absolutely love this preamp. I once swore I would never get rid of it and may still come to my senses. I got it here on Talkbass 5-6 years ago in a trade. (Before the feedback system was put in place.) Numerous changes throughout the years to my rig have taken place but this preamp has remained in my rack. One striking thing about it is every bass I plug into it sounds good. My $129 SX bass sounds almost as good as my $3000 Lakland. Enough of that or I will talk myself right out of this. For full disclosure there is one problem with this unit. The crossover doesn't function like it should. When you go out of the high and low outputs the gain is weak. Also, the knob that controls the high frequency level just spins with no stop. To me this is nothing because the crossover in this unit is pretty crappy anyway. (6dB filter only) The rest of the pre functions perfectly using the full range output and sounds awesome. Last year I was having some gain issues and I had this completely checked out. Contacts were cleaned and a couple solder joints redone but I was told initially that the pre was OK. As far as the crossover, the tech was having trouble finding a pot for it and I decided against having this fixed anyway. Apparently the high frequency pot in the crossover is the culpret and a replacement would bring it right up to spec. Turned out the gain problem was my QSC amp taking a crap after 6 years and I had it fixed by QSC authorized service. Everything is good now. What am I looking for in a trade? I don't know... Wanting to try a Avalon U5 lately or any other mic pre. Got one with rack ears? Maybe an Eden Navigator? Tube or Solid State, run it by me. I have tried numerous tubes in this and the 2 best I have run across are a Mesa Boogie 12AX7 and a Phillips 5771. I have a hard time deciding between the two so will include both if we do a deal.
