SO, here's a moody shot from last night after I went and gigged Sat/Sun this weekend just gone. Had an insane amount of fun running this rig and I thought you might appreciate it!
Ibanez ATK810 bass
In the 6u rack is:-
-Furman M10LXE power conditioner
-Korg DTR1000 tuner
-Ampeg SVP-BSP preamp
-Mesa Boogie Triaxis preamp
-Rocktron Velocity 300 poweramp
Mesa Boogie Diesel 4x10 cab
Signal path is:-
Bass -> Ampeg -> Rocktron -> Cab
Ampeg Tuner out -> Korg
Ampeg Overdrive FX Loop Send -> Mesa Input -> Mesa Output -> Ampeg Overdrive FX Loop Return
Essentially, I'm using the Mesa guitar preamp for my overdrive tones, it has this real nice raw sound that I'm digging right now! Otherwise, the clean channel on the Ampeg is always running and I combine the Overdrive channel as and when required.
