Here's my latest rig. I used to love my old rig - an Aguilar AG500 + two GS112s but it was heavy and required three lifts, which isn't funny when you've got arthritis. Anyway, I bought this staggeringly good Accugroove Whappo jnr from my good mate Cameron (wayne58). It's on castors so now my bass goes on my back and my Little Mark Tube head and bits bag go on top of the cab and I wheel it all in to the stage in one go - needless to say my back / dodgy hip are much happier. It's a fairly easy lift into the car and the whole lot just wheels in to Harry Potter's cupboard under the stairs when I get home.
I'm really happy with it and it's drawn a lot of positive comments. It's very articulate, deep and it literally shakes the ground and when I was soundchecking at our last gig, the sound engineer came down from the control room to see what my rig was and he said he hadn't heard anything as good.
I opted for the tube version of the LMIII because of the extra bit of control DI'ing and the mute switch helps. Blending the tube in does make a difference to the tone too.
