I'm think of picking up this: http://www.behringer.com/HA400/ Basically I want to use it as a practice headphone "amp" until I can afford the Sadowsky Pre/DI. I have a little one at home now and practicing through the main rig just isn't going to happen. I figured I could pick this up (retail $20) and basically use it until I saved up some cash for the Sadowsky. My plan is to go direct into it, use one headphone jack for headphones, one for a tuner out, and possibly another to go to my amp, and the 4th to go into my PC for recording. Does anyone use these, or see me having a problem with this? My current bass is an SR400 with replaced pickups - Seymour Duncan QP's - so it's passive now with no pre. Will this amp be able to boost the signal to a listenable level or am going to have to wait to get the Sadowsky? Thanks for your help!
