Hi there,
Well after a considerable search I decided to buy a Markbass Cab, the 410HF.
My current set up is a Genz Benz Shuttle 6.0 and 2x GK Neo 112 cabs. My axe is a Gretch Thunderjet.
I wanted something with a little more power and grind than I was getting from the 12 inch speakers, though I love their portability. They always seem rather middy, a bit waffly and mellow to me. Great as PA speakers though, so Hi Fi, so I'll probably keep them for bass practices and for PA sound.
Anyway I liked the Markbass sound and they seem so popular, they are never for sale on ebay, so new is the only option. I hope I did the right thing with getting a 4 Ohm. I was orginally looking at a rig, like a 410 plus a 210 or 112 to take to practice, but everyone said that a single 410 will be all you will ever need for any gig, and with 4 Ohm I get the full 600W from the shuttle head. I only do occasional smallish gigs anyway, we are not a big loud band.
How exciting. We do a gig Sat night and I get to use it!
