No advantage that I can see - I've tried using both (stereo mode on my Poweramp) and just one when in parallel mode. No real difference that I can tell. I've mainly just been using one output and using the parallel setting on my poweramp. One nice little feature I have used (but just played with it so far) is to introduce a pedal or two (whilst in stereo mode) in between, say channel A, and leaving the other channel alone. So in effect I get a nice blend with each speaker cab getting a slightly different signal, and there are of course my main pedals in front of the pre-amp to start with too.
I'm going to be buying another cab (4x10) when I get my taxes back, and got to thinking what the difference in signal going out of either output was. I am planning on running one output to either side of my Aphex 204, and from there running each channel to my SVP1600 (a real stereo power amp). Sure would be nice to have had 2 seperate channels on this amp, and an effects loop. If I could get a 1u pre that could do that and sound this good, I'd really have to think hard about taking a look at it...
Awesome - it's simply the cleanest pre- I've ever played on. I play it through a PEAK 1600w poweramp !CRANKED! and there's not a even suggestion of hum or hiss - nothing! The only noise i get is the fan from the poweramp. (I play a Passive bass.) (BTW - i use cheap leads and without balanced input cable) One feature I especially like is the "Ultra-Low" selector, it makes it quick and painless to simply dial in an EQ, without needing to sit there for 10 minutes fiddling. The other thing i love is the bass - my last head (Warwick) was thin and flat and simply didn't have enough low freq. presence for me - the ampegs' got enough for me to have to back it off! You won't be disappointed - thats for sure! smo
The mids are great - they cut through nicely. (I tend to back the mids down to about 9 o'clock actually) I generally play alongside an Orange OR120 and a Klempt Eccolate - both tube amps, and both have a very dark/low tonal response, so getting through for me is quite an issue. But - with an SVP-CL and 1600w, it's not very hard. I've been told about the variations that different tubes make, and I think I may try this out sometime in the future, but for now the Groove Tubes are just fine. smo
