I've been gigging with my Hartke LH500 into a Kappalite 3015-loaded EV TL606 almost exclusively for the last 6 weeks or so. This weekend I decided to try out my other rig, a GK 700RB Series I into my Carvin BRX10.2 Neo cab (pic taken in garage, not at the gig lol):
I mostly wanted to try this rig out for a couple of reasons. First, it's nice and portable, a one-trip load in and out. Second, I'm about to start doubling on upright with this band, and I strongly suspect that this rig will work better for upright than the LH500/TL606.
I hadn't really tried before, but I was able to dial in a very warm tone. Not as "clean tube" as the LH500, but very full and warm. Had the boost at noon, treble cut to 10:00, hi mids noon, low mids 1:00, bass cut to 11:00. Contour and presence at zero, and the 5-string button engaged. WIth my fretless P-bass, it was really very nice.
I really like this little rig. I'll be gigging it a bunch, I think. Not that I won't be playing the LH500 though ... I still love that head!
Cheers,
Liam
