I have been playing bass for a while now I feel like I want a new amp im looking for a more punk or grunge sound any one know of some good ones
I think you may need to share a little more info as to what you are looking for, how much you want to spend etc.
If I had the money to buy an amp right now I would get a TC Electronic RH750 with 2 RS210 cabs and the footswitch. 750 watts, 3 tone presets (save your 3 favourite tones) 4 band eq and you alter the center frequency of each eq band. compressor, tweetertone, tubedrive, tuner, d.i out, digital xlr out, aux in, headphone out 1/8in (only bummer to me) Effects loop. Portable. But of course that's what I'd get. Check the youtube vids it's a pretty damn impressive unit
GK is great stuff too, a lot of the stuff out there is really good. Like we are living in a golden age for bass gear. There's never been as many choices as we have at present.
