Ok so I have returned from Hamburg and indeed succeded in visiting the Bass shop there and I was impressed, it was a fairly small shop but piled to the celling with gear, Sadowsky, Yamaha TRBs, a large selection of Warwicks and Fenders but of course, the crowning glory of the room... the Tech Soundsytems rig. Ignoring the Ampeg, Mesa, Ashdown and SWR rigs there I headed straight for the techs. So, here's how the rig lined up: On top: The discontinued Graphic 1000 head. Beneath: Finished off with a: So, down to business. Firstly, I made a point of picking up an old passive 200 euro 4-string P/J Yamaha and pluging it in. Eq off, all tone controls set to flat, all controls on bass to flat, amp into passsive mode. Gain set to 1 along with master volume at the same. I sat down, picked up the bass and started playing some Zender. Suddenly it happened, I felt the worst GAS I have ever felt in my life. The amp had taken the cheap bass and turned it into something incredible, it was so tonally pure it was untrue, everything just sounded so. Finger, slap, pop and tapping all sounded like the carefully crafted tones you hear in studio recordings, it was simply amazing. Oh and spectacularly loud even at the measly gain and volume settings. Crystal clear sound, no harshness or dullness, no pronounced frequencies, no coloured sound just pure bass as it should be. After 15 minutes it was time for a change... Off the wall came a brand new Yamaha TRB-5PII, the amp was switched to active mode but everything else remained the same. I started out by giving the low end a thorourgh workout, I slaped and fingered the B relentlessly but the cabs never even broke sweat, an awesome low sound. The overall sound was simply perfection, I can honestly say that I think nothing would ever sound that good. I also tried a 'Wick FNA Jazzman 5, Modulus Q6 and a Cort Curbow 4 and all of them let the individual personality of the bass shine through, the 'wick growled just how it should do, Q6 didn't manage to trouble the rig at all even when pushed all the way to the last fret of the C string. Turning the volumes up to painfull levels, the amp remained free of hiss, when the eq was used it was too, the cabs didn't show a hint of distortion. So here's the conclusion, I think you will never find anything that can compare to Tech, I have never had a more enjoyable bass experience than those few hours I spent with that rig. The prices may be high but nothing compares, you can not judge them against any cabs because they are just superlative. If you have any questions then feel free to ask and I'll try to rack my brains.
