I know it's not the BEST idea to do something like this, especially for a tone freak such as myself, but I'm sort of in a situation that requires it........I'll explain. Most sound engineers prefer to supply me with their own crappy DI box for a line out the board (which irks me), and would rarely, if ever, let me line out through the SVT-4 instead (which would be superb). This negates the MUTE function on the amp that I normally use for silent tuning (using the Tuner Out function, and keeping the tuner out of my signal path). So, I've since bought my own QUALITY DI, (Sansamp BDDI), and am running my signal as such: Bass --> Sennheiser Digital Wireless --> DTR-2 Tuner --> Sansamp BDDI --> SVT-4 Pro, using the MUTE function on the tuner for silent tuning. I AM, however, running into the problem that most people have complained about around the 'net, though not as severe as most have said. The added noise (hiss) is noticeable at very high (past 12 o'clock) volumes, but is not a huge deal for quieter gigs and rehearsals. I did read a review on Harmony Central that states that this problem has been addressed and fixed on the DTR-1000. So now I'm thinking of upgrading my tuner to the DTR-1000 from the DTR-2, and my problems would hopefully be solved. Here's a pic of my rack setup so you can visualize what I'm dealing with, it may help. Opinions from anyone and everyone would be MUCHLY appreciated! Thanks in advance!
