I am using a 2000 Warwick Streamer Standard with twin MEC passivepick-ups through a SABDDI into the passive input of an Ashdown Mag 2x10T Combo. The problem I have is that, even if I use the SansAmp with the Level full on (bearing in mind that Tech21 suggest you run the Level at 12.00 o'clock unless you are driving a Power Amp) and with the input level on the amp full on, I can only "just" get the VU on the amp to flicker slightly. I can't get anywhere close to getting the needle to peak into the red occasionally to give me what Ashdown suggest is the "optimum input setting". The only way I can get the needle anywhere red lining is by cranking the Drive and Bass controls and then my tone deteriorates. That being the case, the signal received by the power amp stage of the Combo is obviously not nearl as hot as it should be and I'm assuming that this means I will be driving the output stage much harder than would otherwise be the case. I have established that it is NOT a problem with the SABDDI (I have used a friends with exactly the same result). It is NOT a problem with the amp (I have tried my bass and SABDDI with other Ashdown heads and Combos - ABM and Mag - with exactly the same result). Also, I have checked with MEC on the correct output of the pickups and it would seem that they are performing exactly as designed (albeit at about 10% of the output of the passive pickups on my 40 year old Gibson!!). I wonder whether anyone out there has experienced the same problem and what the solution might be. I'm looking at a possible pickup upgrade although I am a little nervous of this as I am VERY happy with the tone of the bass as it stands. If I'm honest, I suppose where it not for the VU on the front of the Ashdown, I might never have realised that the output from the pickups was so low and , in that case, ignorance may have been bliss. So, do we think this is a "problem" worth solving and if so how? Or do I just ignore the VU and carry on as I am? Is it likely that I will do the amp any harm by virtue of the fact that I am pushing the output stage harder than I should be due to the poor input level. All help gratefully received as always.
