Bringing up a bit of an older thread, but it's around the decision I'm looking at at the moment. Currently using a Markbass 115 cab with a GK 1001-II head and looking to move to a lighter, smaller amp. I like the tone at the moment, but would prefer something cleaner/flatter/more transparent. My OCD side would prefer to keep it all the same company, but I'm quite tempted by the Tone Hammer 500, especially as I'm also considering the TH preamp/DI pedal for when I'm playing ampless.
