Hi, was a bit unsure where to post this on TB but I thought here may be the most appropriate. Anyway, I have a question/observation. Firstly I guess you should know what I'm playing. I play a Fender V and a Warwick FNA Jazzman 5 through an SVT-VR and a Bergantino NV412. I find that when I increase the treble on the either the bass preamp, or flick the ultra high on the SVT (for example), it makes a huge loss of low frequencies and a huge loss of punch on the upper strings, especially above the 12th fret. The low strings B E A sound round, crunchy, etc, but everything else sounds piddly weak in terms of both volume level and tone. For example (when I have the ultra-high engaged), I hit a low B string and it sounds loud, bassy, deep, punchy. Then I hit the G string on the 14th fret and it sounds twangy, no punch, and about 1/3rd of the volume of the B string. Why the hell is this? It happens on both my basses. I would expect it to be a bit twangy but still bassy, ballsy, and most important, the same volume output on all the frets. I've heard great bass tone from other bassists before where it sounds twangy, punchy, full, and even across all the frets they play. What am I doing wrong?
